Timco self-drilling screws for heavy section steel with EPDM washers. 100pc pack, 5.5x55mm. No pre-drilling needed.
The Timco Heavy Section Screws provide high-strength fastening solutions for metal-to-metal applications. These self-drilling screws eliminate the need for pre-drilling through their hardened carbon steel drill tip, making installation quick and efficient. The screws are designed to attach metal to heavy section steel (maximum 12mm thickness), ensuring robust connections in structural applications.
Constructed with an A2-304 austenitic stainless steel body and a bi-metal composition, these screws offer excellent corrosion resistance and durability, making them suitable for exterior applications. The fixed EPDM washer ensures a watertight seal, preventing leaks and enhancing the fastener's effectiveness in outdoor environments.
