Timco Metal Construction Screws - Countersunk, Wing-Tip, 4.2 x 38mm, 200pk
Timco wing-tip self-drilling screws for wood to metal (max 3mm) with exterior coating. 4.2x38mm, 200 pieces.
The Timco Metal Construction Screws are specifically designed for secure fastening of wood to light section steel (maximum 3mm thickness). These self-drilling screws feature a coarse self-tapping thread with innovative wing-tip design. The wings efficiently ream out the timber, allowing the screw to achieve maximum RPM without burning out. When the wings contact the metal surface, they break off, permitting the thread to self-tap into the metal for a strong, reliable fix.
Boasting exterior plating with silver organic coating, these screws offer exceptional corrosion resistance - proven to withstand 500 hours of salt-spray testing. The hardened carbon steel construction (case and core) ensures durability and high strength performance in demanding exterior applications.
