Description

These self-drilling wing-tip screws are specifically designed for attaching wood to heavy section steel (max 12mm thick), complying with BS EN 10666 (DIN 7504) standards. The innovative wing design reams out timber to prevent burn-out at high RPMs, then breaks off when contacting metal to allow self-tapping into steel.
