GRK's RSS screw is made of specially hardened steel to provide you with high tensile, torque, and shear strength. The sharp threads and points bite instantly into the material (including hardwood), reducing the splitting effect due to smaller shanks.
The PWR Drive CST screw is made from hardened steel to deliver superior strength and driving torque that far exceed what standard lag screws can offer. No pre-drilling is required with the Type 17 self-drilling tip, which also saves time on the jobsite, minimizes splitting, while the sharp threads and a “U” clearing thread reduce friction along the shank. The result? Lower driving torque and extended battery life for your tools. The wide flat head features nibs and under-head cutting serrations, ensuring smooth, clean countersinks and flush finishes every time. The T-40 Star Drive provides a firm grip that keeps the screw securely attached to the bit, even when working overhead or in tight spaces. Watch the video to see the CST in action and discover the difference for yourself.
HeadLOK is a heavy duty structural wood screw that is ideal for many wood applications including deck framing, stair stringers, attaching rigid foam (SIPs), fences, kitchen cabinets and more. The HeadLOK flat head fastener requires no predrilling and offers higher design shear than 3/8 inch lag screws. The SpiderDrive System contains 8 points of contact, maximizing bit fit and reducing stripping. HeadLOK zips right in and creates a great finished look.
General purpose, heavy-duty structural fasteners designed for wood-to-wood construction without pre-drilling. Structural lags are ideal for a variety of indoor and outdoor projects.
