Product Description

These Metal Construction Timber to Heavy Section Screws are engineered for fastening wood to steel with speed and strength. The wing-tip design clears timber smoothly before breaking off to let the self-drilling thread cut cleanly into metal. A hardened carbon steel drill tip combined with a stainless steel body provides strength, corrosion resistance, and durability for exterior or industrial applications. The countersunk head ensures a neat finish while maintaining secure fastening. Designed for builders, fabricators, and contractors, these screws deliver reliable performance where timber meets structural steel.
