Multi-read content what size deck screws

14To share

When I wasbuild my patioA few summers ago, I was amazed at the number of shoelace options available. It helps if you fasten everything together with one size screw, but doing my research I realized that would be a very big mistake. So I need to figure out what size screw to use for the floor.

You need a different screw for each part of your deck. 8-gauge 2.5″ deck screws are most commonly used to attach deck boards to tie bars. For deck framing, structural wood screws such as the 1.5″ Simpson SDS screw work with hangers and tie rods, as do column/beam brackets. Railing posts require galvanized through bolts or ½” diameter stainless steel, while railings will require 3.5″ coated deck screws for posts and rails.

Below, we’ll go over your options for screw sizes to use for floors, from posts and beams to railings.

What Size Screws for Decking

Learn more about decking screw sizes

When you buy any type of screw, you will see a series of numbers on the packaging. These numbers are important and if you don’t know what you are looking for, you will end up with the wrong screws.

Also, understand that screws and nails are different and have different quantities. Don’t assume that 16d nails are the same as ¼” screws, because they are not.Screws are a completely different animal than nails, and when used correctly will be more effective.

To save you trips to and from the nearest Home Depot, let’s break down what these numbers mean.

Gauge

The gauge is the diameter of the screw. The higher the gauge, the larger the screw. For flathead screws, you can look at 8 or 10 gauge screws. Specifically, 8 gauge equals a diameter of 4mm.

If you’re using structural wood screws, you’ll probably use a ¼” diameter screw. They’re also known as 14 gauge, but are often labeled as ¼”. Any screw over ¼” in diameter is listed by its actual diameter, not the gauges.

Length

This is quite understandable. After the gauge or diameter, the next number listed on a screw packet is the length.

As a general rule, the screw should penetrate at least halfway into the piece of wood under the piece you are attaching. But when attaching deck boards to beams, 2.5″ deck screws are usually quite long because more than half of the screws are buried in the beams.

When using screws to attach brackets such as storm poles and hangers, you may need shorter screws so they don’t protrude from the ledger or backplane. In this case, ¼” SDS 1.5″ or 2″ structural screws are suitable.

Theme Size

Many flat head screws will not have the thread sizes listed, as the term “bridge” usually indicates a coarser thread. When you use the word “coarse” to describe thread size, it simply means that the threads are further apart than what is found on machine screws.

Wood, deck, or multi-purpose screws designed to use treated lumber will have similar thread sizes – that’s fine.

Types of flat head screws

There are many different typesbridge screwthere and it can be overwhelming to stand on Home Depot’s secure walkway. Let’s take a look at the different types of flat head screws.

Conventional deck screws

“Normal” flat head screws are steel screws coated with zinc or other weather resistant coating. Usually they are green or brown in color and come in a variety of lengths and sizes. This is the most commonly used, cheapest and most effective flat head screw. Do not use in shear force applications.

structural screw

Structural screws are thicker screws specifically designed to withstand loads. This means that these screws can be used instead of nails when attaching braces to ledger boards, beams to tie rods and balustrade posts.

Although these screws are available in many styles, they are usually ¼” or larger in diameter. They will have a corrosion resistant coating and are generally made from higher quality steel.

Hidden ground screw

Hidden deck screws are just that – hidden. These are brand specific screws that work in tandem with jigs or brackets. Camo Brand Hidden Deck Screws use hand jigs that fit the width of the floorboard, with corner holes at the ends allowing you to drill deep through the sides of the board into the tie rod.

All of these systems are designed to provide the clean, rugged look of traditional screws.

Stainless steel floor screws

Stainless Steel Deck Screws are ideal for any outdoor application as they are highly rust resistant. However, their higher cost than regular wood floor screws makes them less popular.

When installing cedar flooring, stainless steel screws are required. Coated screws may leave residue or yellow spots over time as the coating soaks into the wood. Stainless steel, uncoated screws will not discolor cedar.

Composite fasteners

Screws used with composite decking generally have much smaller heads and tighter threads. The smaller tip reduces tearing of the composite. In some cases, these screws have a reverse thread just below the screw head. A reverse thread ensures that the screw sits flush with the composite deck board.

Composite screws, with their narrow threads, also have the advantage of not requiring pre-drilling. This saves a huge amount of time. All composite screws have a weather resistant coating and a star or torx head.

Late closing

Lag bolts are a proven method of attaching two pieces of wood in shearing applications. These bolts usually have hex heads and are at least ¼” in diameter. However, unlike typical bolts, lag bolts have a pointed screw-like end.

Locking latches are ideal for posts or ledger boards, where deck construction requires the bolts to be buried in the wood.

What size screw to use for the floor

Now that we know the difference between the different types of screws available for your next decking project, let’s find out the ideal screw size to use for each application.

terrace board

The main goal of your deck, you want your deck to be secure and beautiful. For most of us working on a tight budget, covered deck screws are the most viable option. Standard green or brown coated screws are the least expensive. Deck screws 3″ in length are preferred over 2.5″ because they hold better.

A

If you prefer a cleaner look to your deck board, CAMO screws are ideal. Unlike other concealed systems that use brackets between deck boards, the CAMO system is based on a handheld device that adjusts to the width of the deck. At the ends the fixture has two corner holes to ensure the screw is securely fastened diagonally out of sight.

CAMO decking screws are available in a variety of lengths, the most common being 2 ⅜”. These screws are also coated but narrower at

Finally, the CAMO fixture is adjustable, so if you have cut your deck to the correct 6″ width or any other width, the fixture will change to fit. Remember, a CAMO deck screw barrel doubles the number of conventional deck screws, not to mention the cost of the unit.

Another advantage of the CAMO Installer Tool is that it provides an automatic featureground distance.

Publish to Beam

When attaching columns to beams, the use of galvanized beam brackets/caps is ideal. First, it places the weight of the beam completely on top of the post and it allows you to drive structural screws through the galvanized post cap.

Simpson Strong-Tie Galvanized Post Caps must be used with Simpson SD

Beam joists

Using hurricane ties to attach tie rods to a beam is ideal. Again, I recommend Simpson SD

There are several different styles of storm lanyards, but this screw only needs the Simpson brand. While the cost of 16d galvanized nails is about 4 or 5 times higher, these screws are much stronger. Also, it may be faster to move the screws through the bracket than to drive the nails.

Join ledger board

Attaching a joist to the ledger board requires a joist hook. Use one

When installing the hangers, the space is sometimes higher depending on how your deck is installed. It is not always possible to rotate the hammer due to space constraints, making screw control more desirable.

balcony

Installation of railing posts depends on local building code requirements. For the most part, ½” diameter galvanized bolts driven through tie rods in the railing post work well. These bolts have a hanging thread, a pointed end like a regular screw, and a hex head. The 6″ long pin is sufficient for use with 4×4 railing posts.

Some building codes require that a tension tie be used in conjunction with a transport pin. The turnbuckle is a galvanized bracket screwed to the deck beam behind the balustrade post. The tie has one eye looking directly at the railing. A hole is drilled through the rim brace, the railing post and the side brace for the transport bolt through the three pieces of wood and the turnbuckle.

Ideally, use carriage bolts with Simpson tie rods. It is much stronger than the lag bolt simply because the handrail post is fixed on both sides, while the lag bolt attaches the post to one tie rod only. Stressed relationships were logged to participants using Simpson SD

Stairs

The steps do not support the load. Therefore, standard flat head screws can be used. If you are using standard decking, which is pressure treated for the grooves, then

The wooden lanyard is held in place by a wire holder, which is screwed down. The Simpson Galvanized Lanyard Holder is designed for Simpson SD use

Metal strapping machines require galvanized lag bolts instead of SD screws and brackets. These hysteresis bolts should be ½” diameter and long enough to penetrate almost the entire frame behind the turnbuckle.

Use screws for different floor materials

The important thing to remember when choosing screws is to be consistent. If you are purchasing galvanized hangers and post caps, you will also want to use galvanized screws. Mixing and matching can lead to corrosion and structural failure.

The pressure is managed

Galvanized screwsis the cheapest and one of the most reliable screws to use on pressure treated lumber. However, the copper commonly found in today’s pressure treated lumber will eventually eat away at the zinc.

If you have the money, splurge on stainless steel pressure-treated wood screws. They will last longer because they are uncoated. Stainless steel uses nickel and chromium mixed with steel to create a product that is extremely resistant to corrosion. Although it may cost up to ten times the amount, it will still be peanuts compared to what you spend on your flooring.

Cedar

Cedar requires a hidden decking system or a stainless steel decking screw. Over time, covered deck screws will blend into the cedar and dull its natural look. As the stainless steel screw is not coated, there is no risk of discoloration of the wood around the screw.

synthetic

Composite decking screws require material specific screws. Simpson Strong-Tie is an excellent DCU Deck-Drive composite screw. I recommend them

The small head of these screws reduces any fungus in the material while the thick diameter provides ample clamping force. A small head also helps improve the surface appearance of the deck.

Conclusion

I hope you enjoyed this article on how to find the screws that are best for your deck. As flooring products evolve, it is important to understand that not all fasteners work with every substrate or wood. Do your research and ask questions – don’t rely solely on warranties or product warranties.

Popular questions about what size deck screws

what size deck screws?

Deck screws measuring 2 ½ inches and 3 inches usually work best for fastening railings, deck boards, and joists, while 6-inch deck screws are necessary for 4×4 posts.

What size deck screws should I use for 2×6?

Typically, the thickness of the 2×6 decks varies around 1.5 inches. As you will need approximately 1 inch of penetration, the 2.5 inches to 3 inches deck screws will be the best choice. If you prefer bigger penetration, like 1.2 inches or 1.5 inches, screws around 3 inches will be the best choice.

How deep should screws go into decking?

How Deep Should Deck Screws Go? Deck screws should be placed at least 1” away from the edge of the board. If you install the screws too close the edge, you increase your chances of splitting the wood. The general ‘rule of thumb’ is that the screw should reach at least halfway through the board.

What size screws 2×4 deck?

The screws normally used to install 2x4s or 2x6s for decking are 3 in. L and have 1 in. of unthreaded shank. Since 2×4 and 2×6 deck material is 1-1/2 in.

Do I need to predrill for deck screws?

Deck screws installed in the field, not close to the board’s end or edge, need not be predrilled. Predrilling is required near the end of deck boards to make room for the screw. As the screw is acting like a wedge, driving between the wood fibres. That screw pushes against the decking, splitting open the board.

What size screws 19mm deck?

10G x 60mm
All Timber decking is recommended to be screwed with Stainless Steel decking screws with a minimum 10G x 60mm length for 19mm boards and 12-14G x 80mm length for 32mm boards. It is recommended to use a screw fixing with a Torx driving fixture and the use of a square drive head is not recommended.

How do you know what size screws to use?

The general rule of thumb is that the screw should enter at least half the thickness of the bottom material, e.g. 3/4″ into a 2 x 4. The other factor is the screw’s diameter, or gauge. Screws come in gauges 2 through 16. Most of the time you’ll want to go with a #8 screw.

How many deck screws will I need?

The general rule of thumb for standard deck fasteners is 350 screws for every 100 square feet of decking, which is based on standard 6″ wide boards (5-1/2″ actual), and 16″ joist spacing.

How do I choose deck screws?

A 3” length deck screws are preferable to 2.5” as they hold better. A #8 diameter deck screw is ideal, as any higher would split the wood. Remember, if you are using cedar, then you should opt to use a hidden fastening system as these coated screws will stain your cedar.

Should I Gap My deck boards?

Leaving a gap between boards is critical for a well-built deck that will have space to drain, dry, expand and contract without causing the wood any damage. But, you also want to be sure you leave the right size gap: Go too small, and there won’t be enough space; go too big, and the gap can become a safety hazard.

How many 2 inch deck screws are in a pound?

A: There are approximately 80 deck screws in the 1 lb. box.

What size is #7 screw?

151″ 5/32″
Wood Screw Diameters
Size Major Thread Diameter*
Decimal Nearest Fractional Measurement
#6 .138″ 9/64″
#7 .151″ 5/32″
#8 .164″ 5/32″

How strong are deck screws?

Deck screws are not designed to resist shear like bolts and bolted joints are. That being said, most screws can hold between 75-125 pounds with more quality deck screws being able to hold above 200 pounds per screw. You can also double up the screws to hold more weight.

Why are my deck screws breaking?

Why Do My Deck Screws Keep Snapping? The most likely cause of deck screws snapping is a combination of the boards and the screws. Simply, if the boards shift, it alters the pressure on the screws, and they may snap.

How do you screw deck boards without splitting?

Don’t Use Screws That Are TOO LONG or TOO SHORT! (Screw Length/How To Choose The Right Screw Length)

People often ask how much screw they should use for fastening boards together. Screw length can be a tricky thing to figure out. This short video from The Honest Carpenter will show you a few rules of thumb that can help out in almost any situation.

The screws in this video fall int the “Utility Screw” category, and are “deck screws” in particular. This is a very good, common screw to use for strength in household projects.

#8 is the most common deck screw gauge. But, thicker #9 screws are showing up more frequently on the market as well these days.

If you’re connecting two boards through the cross-grain, then you ideally want 1 to 1-1/2″ of screw thread in the BOTTOM BOARD.

However, if the bottom board is thinner, like 3/4″, then too much screw will punch through the back. In this case, size down to a 1-1/4″.

When in doubt, used more fasteners! But be sure to provide them a little spacing–at least 3/4″ apart.

When connecting into end grain, you need more screw length, because end grain doesn’t hold screws very well. You ideally want 2″ of screw thread in the bottom board. So, for 2×4 stock, you want to use a 3-1/2″ screw.

However, if your stock is thinner here, like 3/4″, then 2″ of screw in the bottom board has a higher probability of breaking the wood, or bulging it. You may want to size down to a 2″ screw overall.

RULE OF THUMB: In this application, you want 1/3 of the screw in the top board, and about 2/3 in the bottom board.
