Common Questions About Clamp-Fix Screws
Clamp-Fix screws are designed for internal joinery and heavy timber fixing where high clamping force and a clean finish are needed, such as cabinetry, studwork, chipboard floors, and structural timber applications.
The twin-cut tip reduces the need for pre-drilling in softwoods, but pre-drilling is recommended for hardwoods or precision installations.
TX (star) drive improves driver grip, reduces cam-out, and allows more torque without slipping — ideal for dense or structural materials.
Clamp-Fix screws provide greater clamping force than standard woodscrews, thanks to their reinforced head, twin-cut tip, and TX drive. They reduce splitting, cam-out, and installation time — delivering stronger, cleaner results in dense or structural materials where standard screws may fail or require pre-drilling.
