Black Exterior Deck Screws with T25 Torx Drive – 1000hr Salt Spray Rated, Self-Tapping, Bit Included

Standard silver screws stand out against dark-stained decks, and Phillips bits strip before the job is done. If you're building or repairing a deck, fence, pergola, or outdoor structure, you need fasteners that disappear into the wood, drive without cam-out, and hold up through years of weather. These black exterior deck screws deliver on all three — and come with a T25 Torx bit so you're ready to work immediately.

Featuring a black oxide coating that exceeds ASTM B117 salt spray standards (1000+ hours), these screws resist UV exposure and temperature extremes from -40°F to 150°F. Available in sizes #8x2, #10x2-1/2, #10x3, and #10x4, with quantities from 80 to 400 pieces per pack. The T25 Torx 6-point star drive reduces cam-out by approximately 80% versus Phillips, and the self-tapping #2 drill point drives cleanly into most softwoods without pre-drilling.

Ideal for deck boards, joist hangers, railings, composite decking, outdoor furniture, cedar fencing, Hardie board siding, and any exterior wood project where a clean black finish and long-term weather resistance matter.

Black Exterior Deck Screws #8x2 150pcs - HomeDIYer

🪵 Compatible with pressure-treated lumber (ACQ/CA), cedar, pine, composite decking, Hardie board, and most softwoods. Suitable for decking, fencing, siding, pergolas, and outdoor furniture.

❓ Frequently Asked Questions

What is the black coating on these deck screws?

These screws feature a black oxide coating that exceeds ASTM B117 salt spray standards (1000+ hours). It provides UV resistance and withstands temperature extremes from -40°F to 150°F, making it ideal for coastal areas, snowy regions, and long-term outdoor exposure.

Is a T25 Torx bit included?

Yes. Each package includes a T25 Torx driver bit so you can start driving screws immediately without sourcing a separate bit.

Do I need to pre-drill before using these screws?

For most softwoods and treated lumber, no pre-drilling is required — the self-tapping #2 drill point cuts its own path. For dense hardwoods or when driving near board edges, pre-drilling a pilot hole is generally recommended to prevent splitting.

What sizes and quantities are available?

Available in four sizes: #8x2, #10x2-1/2, #10x3, and #10x4. Quantities range from 80 to 400 pieces depending on the size selected. Use the variant selectors above to find the right combination for your project.

Why choose T25 Torx drive over Phillips?

The T25 Torx 6-point star drive reduces cam-out by approximately 80% compared to Phillips. This means faster driving, less bit wear, and a cleaner finish on every fastener — especially important on high-volume decking projects.

Are these screws suitable for pressure-treated lumber?

Yes. The black oxide coating is designed to resist the corrosive chemicals in ACQ and CA pressure-treated lumber, making these screws a reliable choice for treated deck boards, joists, and posts.

What applications are these black deck screws best suited for?

These screws are ideal for deck construction (joists, railings, composite decking), outdoor furniture (Adirondack chairs, pergolas, picnic tables), fencing (cedar pickets, gate hardware), and siding installation (Hardie board, wood panels).

Sturdy, high quality screws

I chose the 4-inch screws. I used them to attach a 2x4 handrail to 4x4 posts on outdoor deck steps. They were perfect for that job. Using 4-inch screws meant that I had 2 1/2 inches of thread into the 4x4 posts. I also used them to repair the deck in places where 3-inch deck screws had failed. The extra length made it possible to use the same hole and screw it into fresh wood. They have a Torx head, and you will need a T-25 bit to use them (not included). The screws are super stiff. I couldn't get them to bend in the slightest by hand. They have a self-drilling tip to bore out new holes. The black paint is nice too, as it is less noticeable than gold once placed. I'm kind of intrigued by the design of the box. It's quite sturdy and the latch is very secure. Overall, I'm quite happy with these. Update: I used these to secure metal handrails to outdoors steps made of railroad ties. They were perfect for the job. Because the screws are so long, my battery powered drill could not drive them the full length. I had to use a plug in drill. It produced enough torque that even T-25 bit on the big drill was jumping out of the screw head. I kind of ate up my drill bit (but it could have been a cheaper one). So that's a testements to the strength of the screws. 1) they didn't snap. 2) the screw head didn't strip. So take that into consideration. Maybe you pre drill the holes or have extra driver bits on hand.

Sturdy 4" Wood Screws

These 4" wood screws appear to be respectable quality. They use that star screw head which gives you better traction when screwing into wood. I have used a dozen of these so far, none of the heads stripped as I was screwing them in. This set does not come with the drill bit, so make sure you have a few of them before hand. This set comes in a convenient case but my case will not stay closed, it keeps popping open, so I transferred the screws to another container. The screws are performing as expected, I have a large job coming up where I will most likely be using the bulk of them. If I find they are not working as they should I will be back to add to this review. But so far so good.

Thick Heavy Duty Screws!

These are excellent outdoor screws! The description says they are galvanized AND coated which should help them outlast the wood they are holding together. (I can not verify the galvanization however with the coating in the way) My package included 2 x T25 torx bits -one long, and one short. Nice touch! Much cheaper than what you get at the local hardware store, and they even include a plastic case. Thanks!
