Description

This is the self-drilling version of TIMCO’s uPVC window fabrication screw, for frames that DO have steel or aluminium reinforcement inside. The self-drilling point cuts straight through the reinforcement with no pre-drilling, which is what you need where a standard high-low thread would not bite the metal. The countersunk head pulls flush into the plastic. Silver zinc finish. Use it for fitting hardware to reinforced uPVC window and door frames.
