Different Types of Deck Screws

Most types of decking screws are available in stainless steel, or high carbon steel with a galvanized, coated or plated anti-rust treatment. Drive types also differ, with Torx (Star), Robertson (Square Drive), Pozi drive and Phillips among the most popular.

  • Traditional Deck Screws

    These stainless steel deck screws have a sharp point and coarse threads approximately two thirds of the length of the screw, with a smooth shank. The head is generally flat countersunk, or bugle countersunk, and these screws are designed for fixing timber to timber.

  • Composite Deck Screws

    Specifically designed for use in composite decking materials, these screws often feature self-drilling technology and smaller heads. Coatings are often available in a variety of colors to match the plank color selected.

  • Hidden Deck Fasteners

    These innovative screws are not visible on the top of the deck boards, either screwing in through the corner of the plank or utilizing a clip system locating in pre-machined grooves in the sides.

The Best Deck Screw for Your Next Decking Project

"Which screw should I go for?" you ask. Here are some things that you need to consider before going for any other options. Remember that stainless steel screws are an investment that will last you way more years than galvanized screws.

Corrosion Resistance:
Firstly, you need to think about where you are building. 304 grade stainless steel deck and wood screws are perfect for inland use as well as high moisture areas and we even recommend 304 grade stainless steel for use in freshwater applications - be is a floating dock or a deck overlooking the lake.

If you are taking on a job that is by the coast and the fasteners will be coming in contact with the extra corrosive salty water such as on a marina, then we recommend 316 grade stainless steel screws which are also referred to as 'marine grade'.

Material Compatibility:
Treated decking and cedar wood contains chemicals that corrode coated and plated fasteners over time. We highly recommend using a minimum of 304 grade stainless steel deck screws when working with these materials, regardless of environmental considerations.

Composite decking on the other hand is basically inert and very stable, so trim-head screws are a good choice here, minimizing screw visibility for a good and clean finish.

Screw Size & Length
Last of all, the correct size of the screw to be used is directly related to the dimensions of the material being fastened.

The general rule of thumb is for the screw to be three times the length of the material thickness being fastened. So 1" thick decking will be best fixed with a 3" long stainless steel screw.

When fastening wider boards, it is worth considering a higher gauge screw, say a #12 over a #10, as a thicker screw with a bigger head generally has better holding power.

Our six popular sizes cover most woodworking applications in this category and are available in a range of convenient pack sizes.

Tips & Tricks When Installing Deck Screws

Use a drill/driver with an appropriate screwdriver bit (included in all our pack sizes) and a depth stop collar or torque control to ensure consistent screw depth.

An impact driver is an invaluable tool, and we recommend using one if possible.

A gut or chalk-line helps to keep rows of screws in perfect alignment.

Use wedges to ensure that gaps between boards are consistent.

Always lay a straight board first and work out from that, checking as you go.

You will seldom go wrong with a stainless steel screw.

FAQs

Should you pre-drill for deck screws?

Yes! In most cases, pre-drilling clearance holes is recommended to prevent wood splitting, especially on the ends of the planks.

Should you countersink deck screws?

In hardwoods, this is the correct way to set the screw heads at a consistent depth just below the surface of the plank. We highly recommend our Starborn combination bit to countersink the head and drill the clearance hole in one operation.

How should I Install the Screw?

Take care not to overtighten and risk damaging the deck board. Stainless steel screws are softer than carbon steel screws. Maintain consistent spacing for a professional finish.

What size should the pilot hole for deck screws be?

There are two aspects to consider in the pre-drilling process:  The clearance hole, and the pilot hole.

The clearance hole should only be drilled through the decking board, and the diameter is to be slightly larger than the screw's thread diameter. If using a new pine substructure, generally it is not necessary to drill a pilot hole for the thread into the substructure. However, if laying new decking on old pine, or if using a hardwood substructure, you will need to drill a pilot hole for the thread. This diameter should be slightly smaller than the thread.

Do stainless steel deck screws rust?

No, stainless steel deck screws, including 304 grade stainless steel screws, are highly resistant to rust and will last for years. You may find even that theses wood screws outlast the deck or wood furniture that they were used to build.

How long will decking screws last?

Generally, stainless steel deck screws can last for many years and should even outlast the decking planks themselves.

How to Protect and Maintain Deck Screws

Stainless steel screws need no maintenance as such. They will turn a little greyer than silver after installation, but this is normal.

All you need to do is to keep your deck swept and clean, and don’t allow leaves and debris to accumulate.

Note that any screws that may stand proud of the decking surface due to wood shrinkage over time. Drive these in flush as you would when installing.

Durable, Corrosion-Resistant, Versatile

Choosing the right deck screws is important as you want your deck to withstand the tests of time as well, age well and never get those rust stains we all know so well.

304 grade stainless steel deck screws offer a number of benefits, including corrosion resistance, durability, strength, and versatility and by choosing stainless steel, you can be sure that you will certainly have a sturdy and visually appealing deck that will stand the test of time.
