GRK Fasteners RSS™ 5/16 x 4 Inch, Structural Screws, 400 PCS, Rust Resistant Climatek™ Coating, Heavy-Duty Framing & Decking Screws, Fast Bite Tip, Star Drive Recess, Gold

Product Description GRK FASTENERS 10225 10225 RSS 5/16" x 4" SCREWS 400CT From the Manufacturer GRK's RSS screw is made of specially hardened steel to provide you with tensile, torque and shear strength. The sharp threads and points bite instantly into material (including hardwood), reducing the splitting effect due to smaller shanks. The round head with built-in shield (washer type head) has no sharp edges like conventional lag screws. The GRK RSS screw is a great lag screw alternative.

• Heavy Duty Lag Screw Alternative: Eliminates pre-drilling in most woods with Zip-Tip technology. Installs 3x faster than traditional lag screws
• ESR-2442 Code Approved For Structural Applications: Engineered for professional-grade connections in heavy duty framing, multi-ply beams, and timber framing. Integrated washer head delivers maximum clamping force for zero-gap joints in LVL, LSL, and engineered lumber.
• Advanced Corrosion Protection: Rust resistant Climatek coating provides exceptional durability for outdoor use and in pressure-treated lumber applications
• W-cut Thread Design: Reduces installation torque by 40% for smoother, faster driving. CEE threads minimize splitting in dense hardwoods, engineered lumber, and laminated beams.
• Precision Engineering: Star/Torx drive recess with 6 points of contact prevents stripping and minimizes wobble between screws and bits.
