FIX-4-25 is a fastening system developed by FIX LLC and is designed to reduce the time and effort necessary to affix components such as doors, windows, and cabinets to walls and other surfaces. The system consists of four parts: the screw, the drill bit, the fastening hub, and the snap-off locking washer. The screw is a self-tapping, one-piece assembly that is inserted through the construction material and into the fastening hub mounted to it. The drill bit is designed to create an appropriately sized pilot hole, reducing the effort to drill a clean and consistent hole. The fastening hub is designed to provide a secure anchoring point for the screw, and the snap-off locking washer ensures a secure fit by locking the screw into place at the optimal torque. The four components together create a fastening system that can quickly and securely affix components without compromising strength or security.
