For over 20 years, GRK has produced contractor-grade fasteners for professional use, incorporating innovative design features to make screws that are faster and easier to drive and hold better in wood, plastic and composite materials.
These screws all have Torx heads (and are supplied with a matching Torx bit) to reduce the potential for cam-out and slippage in the drive. The hardened steel screws have a rust-resistant Climatek coating that won't react with treated lumber.
Specifically designed for cabinetmaking and installation, these thin-gauge Torx-drive screws reduce splitting. The broad, washer-style heads spread the bearing surface over a large contact area, improving hold and minimizing wood compression. Self-tapping tips eliminate need for pre-drilling; sawtooth-like ridges on threads near the tip reduce friction and driving effort. Also suitable for installing siding.
