Specification Detail MPN 95612 Brand GRK Fasteners / ITW Brands Size 5/16" x 6" Pack Quantity 25 screws Weight 1.76 lb Color / Finish Black (Climatek Coating) Drive Type Star Drive (Torx-style) Head Type Washer Head with Shoulder Coating Certification Code-approved for use in treated lumber Category Hardware / Structural Fasteners Technical Features Zip-Tip Point: Proprietary fast-bite tip design allows the screw to engage material immediately, enabling installation into most woods without pre-drilling and reducing labor time on site. W-Cut Thread: Specially engineered thread geometry bites instantly into material including hardwood, reducing the splitting effect that smaller or conventional shank profiles can cause. Climatek Coating: Corrosion-resistant black coating rated for intermittent moisture exposure in both interior and exterior conditions, and code-approved for use in treated lumber. Washer Head with Integrated Shoulder: The rounded, edge-free washer head eliminates the sharp edges associated with conventional lag screws, providing superior clamping force. The engineered shoulder beneath the washer centers the screw in pre-drilled hardware holes. Star Drive Recess: Six-lobe star drive interface resists cam-out and stripping under high torque, maintaining fastener integrity and drive tool engagement throughout installation. Low-Effort Installation: The combined geometry of the Zip-Tip, W-Cut thread, and full-shank design reduces installation effort significantly compared to conventional lag screws of equivalent structural rating. Applications Structural wood-to-wood connections in framing, decking, and general construction Hardwood fastening where splitting resistance is critical Treated lumber applications in exterior and moisture-exposed environments Hardware connector installations requiring centered, flush screw placement Interior and exterior structural assemblies requiring a finished black aesthetic
