GRK GRK-10273 - RSS™ Rugged Structural Screw, 3/8" x 3-1/8" (400-Count Bulk Box)
The GRK RSS™ Rugged Structural Screw is the ultimate lag screw alternative, engineered to provide the highest levels of tensile, torque, and shear strength. Specifically designed for heavy-duty applications such as structural decking, ledger boards, and general framing, these screws eliminate the need for time-consuming pre-drilling. Built from specially hardened steel and treated with a proprietary Climatek™ coating, the GRK 10273 ensures permanent structural integrity even in the most corrosive pressure-treated lumber environments.
- Zip-Tip™ Technology: Pointed tip enables instant starts with no pre-drilling required, even in hardwoods.
- W-Cut™ Thread Design: Functions like a saw blade to clear away debris, reducing installation torque and preventing wood splitting.
- CEE Thread™: Enlarges the hole for the non-threaded portion of the shank, drawing substrates together tightly with minimal friction.
- Climatek™ Coating: High-performance zinc polymer coating, AC257 code-approved for use in exterior and pressure-treated wood.
- Integrated Washer Head: Large round head with a built-in shield provides immense holding power and a clean, professional finish.
- Recessed Star Drive: Features 6 points of contact to eliminate stripping and maximize power transfer (requires T-40 bit).
