305/304 Stainless Steel Trim head square drive type 17 Deck screw
SS305, 304 and 316
StainGrip® 304 & 305 Stainless Steel Trim Head Square Drive Type 17 Deck Screws are precision-engineered fasteners designed for a clean, low-profile finish and exceptional holding power in composite, PVC, and timber decking applications. Manufactured from premium SS304 and SS305 stainless steel, these screws provide ultimate corrosion resistance against outdoor weathering and harsh wood preservatives, while the small-diameter trim head seats neatly flush to conceal the fastener without surface damage or mushrooming.
Key Features & Technical Benefits
Premium SS304 & SS305 Stainless Steel (Superior Corrosion Resistance): Formulated with high nickel and chromium content to offer long-lasting protection against rust, moisture, and chemical corrosion in demanding outdoor decking environments.
Low-Profile Trim Head (Concealed, Mushroom-Free Finish): Features a compact trim head design that countersinks smoothly into composite and wood deck boards, minimizing surface disturbance and eliminating unsightly mushrooming, burrs, or board cracking.
Deep Square Drive System (Cam-Out Prevention): Precision-molded square drive recess (Robertson / SQ drive) ensures tight bit engagement, delivering superior torque transmission without driver slippage, bit cam-out, or stripped screw heads during heavy-duty installation.
Type 17 Auger Point (Fast Bite & Split Prevention): The sharp notched Type 17 point cuts through dense composite and wood fibers effortlessly, allowing rapid thread engagement and preventing board splitting without pre-drilling under standard operating conditions.
Optimized Thread Geometry: Deep, sharp thread design bites firmly into underlying timber framing, providing high clamping force to keep deck boards secure, tight, and squeak-free over time.
