305/304 Stainless Steel Serrated Head type 17 Deck Screws
SS305, 304 and 316
StainGrip® 304 & 305 Stainless Steel Serrated Head Type 17 Deck Screws are heavy-duty, professional-grade exterior fasteners engineered for high-clamping power, easy countersinking, and maximum structural integrity in timber decking, ACQ pressure-treated lumber, cedar, and composite boards. Manufactured from premium SS304 and SS305 stainless steel, these screws provide exceptional protection against rust, weathering, and aggressive wood preservatives while utilizing specialized head serrations for a flawless, flush finish.
Key Features & Technical Benefits
Premium SS304 & SS305 Stainless Steel (Maximum Corrosion Resistance): Formulated with high nickel and chromium content to deliver outstanding resistance against rust, moisture, and chemical corrosion from pressure-treated lumber, ensuring decades of outdoor structural performance.
Serrated Underhead / Self-Countersinking Nibs: Engineered with specialized cutting serrations beneath the flat head that slice smoothly into timber and composite materials, enabling clean self-countersinking without splitting, mushrooming, or tearing surface fibers.
Type 17 Auger Point (Fast Drilling & Split Prevention): Features a razor-sharp Type 17 notched point that cuts directly through tough wood and composite fibers, reducing driving torque and eliminating the need for pre-drilling in standard deck applications.
Deep Star Drive / Torx® Drive: Precision-molded T20 / T25 star drive recess provides superior anti-stripping torque transfer, eliminating bit cam-out, driver slippage, and head stripping during high-torque installations.
Deep Coarse Thread Design: High-performance coarse thread geometry bites aggressively into wooden joists, ensuring exceptional pulling force, board clamping strength, and resistance to loosening or board squeaking over time.
