Product Description
CompoLock | Premium Stainless Screw for Decking – Turbo Slant Cut
Turbo Slant Cut Tip: Angled cutting edges bite instantly for quick start.
Arc Rings under the head: Multiple biting rings lock the board tightly to the joist for high holding power.
U‑Cut Thread: Cutting shave material as the screw advances, delivering clean chips and effortless driving in dense composites.
Cup head: Keeps the object surface free of tailings and prevents mushrooming around the screw head.
Edge‑safe installation: No splits on the surface close to the edge of the object.
No pre‑drilling in composite & ACQ: Strong tip allows direct driving without pilot holes.
Corrosion‑resistant stainless steel: Excellent outdoor durability for coastal and high‑humidity decks.
Specification
ACQ Treated Wood
Composite Board

Performance Highlights
Faster installation with less driver pressure thanks to Turbo Slant Cut Tip.
Lower risk of board cracking or edge blow‑out.
Strong pull‑down and long‑term joint stability from Arc Rings and optimized thread angle.
Low driving torque curve reduces installer fatigue and extends battery life.
FAQs
Q1. What is the Turbo Slant Cut Tip and why is it faster?
A. The Turbo Slant Cut Tip on this stainless decking screw features angled cutting edges that bite immediately and start the hole while shaving fibers away. This lowers starting torque, speeds up installation, and reduces splitting at board ends and edges. It is ideal for fast and clean deck work.
Q2. How does the cup head design of stainless steel deck screws improve the surface finish?
A. The small cup head design of our stainless steel deck screws, combined with Arc Rings, pulls the board tight while keeping the surface clean and free of tailings. This ensures a flush, smooth finish and prevents composite burrs or splits near the edges. It helps achieve a professional appearance on composite or wooden decking.
Q3. Do I need to pre‑drill when using stainless deck screws for composite boards or ACQ wood?
A. No pre-drilling is needed when using CompoLock stainless decking screws. These advanced decking screw designs are engineered to work directly with composite boards and ACQ-treated lumber. They save time during installation while maintaining structural performance.
Q4. Which stainless grade should I choose for a decking screw: A2 or A4?
A. A2 (SS304) stainless steel is ideal for most outdoor decking screw applications. For environments near the ocean, poolside, or areas with chemical or chloride exposure, A4 (SS316) is recommended for superior corrosion resistance and long-lasting durability.
Q5. What drive bit should I use with CompoLock stainless steel deck screws?
A. The standard drive for CompoLock stainless steel deck screws is T20. Use a snug, unworn T20 bit to ensure optimal torque transfer and minimize cam-out. Other drive sizes can be discussed for OEM or customized fastening requirements.
