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.
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).
