Rust stains on deck boards and stripped screw heads mid-project are two of the most frustrating setbacks in outdoor construction. Whether you're building a new deck, replacing fence boards, or framing an outdoor structure, you need fasteners that resist corrosion for years and drive without cam-out. These brown exterior deck screws deliver both — and come with two T25 star bits so you're ready to work right out of the box.
Constructed from carbon steel with a 4-layer anti-corrosion coating that has passed a 1000-hour salt spray test, these screws withstand sun, humidity, rain, and snow for long-term outdoor performance. Available in sizes #8x2", #10x2-1/2", #10x3", and #10x3-1/2", with 250 to 700 pieces per pack. The serrated 6-contact-point threads prevent stripping and lock the screw firmly without loosening, while the self-tapping point eliminates pre-drilling in most softwoods and treated lumber.
Compatible with ACQ, CA, and CCA pressure-treated lumber, composite decking, and standard softwoods. Ideal for deck boards, fence rails, construction framing, and any exterior wood project where long-term rust resistance and a clean brown finish matter.

These screws feature a 4-layer anti-corrosion coating that has passed a 1000-hour salt spray test. The coating provides superior protection against rust, corrosion, UV exposure, humidity, rain, and snow for long-term outdoor performance.
Yes. Each kit includes two T25 star bits: one 50mm (approx. 2 inches) and one 100mm (approx. 4 inches). The longer bit helps reach recessed screws or work in tight spaces. Both fit standard impact drivers and drills.
For most softwoods, pressure-treated lumber, and composite decking, no pre-drilling is required — the self-tapping point and coarse threads cut their own path. For dense hardwoods or when driving near board edges, pre-drilling a pilot hole is generally recommended to prevent splitting.
Yes. The 4-layer coating is specifically designed to resist the corrosive chemicals in ACQ, CA, and CCA pressure-treated lumber, making these screws a reliable choice for treated deck boards, joists, fence posts, and structural framing.
Available in four sizes: #8x2", #10x2-1/2", #10x3", and #10x3-1/2". Quantities range from 250 to 700 pieces depending on the size selected. Use the variant selectors above to find the right combination for your project.
The serrated (6-contact-point) threads prevent stripping, reduce drive torque, and lock the screw firmly into the wood without loosening or slipping over time. This design provides superior holding power compared to standard thread profiles.
The T25 Torx (star) drive provides better torque transfer and eliminates cam-out — the slipping that strips Phillips screw heads. This means faster driving, less bit wear, and a cleaner finish on every fastener, especially on high-volume decking and fencing projects.
