Timco Self-Drilling Wing-Tip Screws 4.2 x 38 LW4238B 200 Pieces

The TIMCO Self-Drilling Wing-Tip Steel to Timber Light Section Silver Screws are designed to join wood to light steel sections up to 3 mm thick. Featuring a coarse self-tapping thread with wings, these screws ream out the timber to allow for higher RPM drilling without burning out. When the wings contact metal, they break off to let the thread continue tapping into the metal, providing a secure fit. Built for construction and DIY projects, they combine steel construction with a silver finish for durable, reliable performance in light gauge steel applications.
