The TIMCO Self-Drilling Wing-Tip Steel to Timber Light Section exterior screws are designed to join wood to metal up to 5 mm thick. Featuring a coarse self-tapping thread with wings, the design reams timber to allow the screw to reach high RPMs without burning out. As the wings contact metal, they break off to enable the thread to continue self-tapping into the metal. The screw has a hex head with washer and a self-drilling tip, finished in Silver Ruspert for added durability. These screws are intended for light sectional woodworking applications where a steel-to-timber connection is required, combining a robust self-drilling capability with a wing-tip design to help streamline installation.
