305/304 Stainless Steel Trim head torx Deck screw
SS305, 304 and 316
StainGrip® 304 & 305 Stainless Steel Trim Head Torx Drive Deck Screws are engineered for a subtle, low-profile finish and maximum holding power in composite, PVC, capstock, and fine timber decking. Manufactured from premium SS304 and SS305 stainless steel, these screws provide ultimate corrosion resistance against outdoor weathering, moisture, and harsh wood preservatives, while the compact trim head sinks cleanly to prevent surface damage or board mushrooming.
Key Features & Technical Benefits
Premium SS304 & SS305 Stainless Steel (Superior Corrosion Resistance): High nickel and chromium alloy content delivers long-lasting protection against rust, outdoor moisture, and chemical corrosion from pressure-treated lumber, ensuring long-term structural integrity.
Low-Profile Trim Head (Concealed & Mushroom-Free Finish): Features a small-diameter trim head engineered to countersink smoothly into composite and wood deck boards, minimizing surface footprint and completely eliminating unsightly mushrooming, burrs, or surface cracking.
Deep Torx Drive System: Precision-molded T20 / T25 star drive recess provides superior torque transfer and driver bit engagement, eliminating bit cam-out, driver slippage, and stripped screw heads during heavy-duty installation.
Type 17 Auger Point (Fast Bite & Split Prevention): The sharp notched Type 17 self-drilling point slices cleanly through tough wood and composite fibers, allowing fast thread engagement and preventing board splitting without requiring pre-drilling under standard conditions.
Optimized Thread Geometry: Deep, sharp thread design bites firmly into underlying timber joists, delivering exceptional clamping force to pull deck boards tight and eliminate board squeaking or cupping over time.
