Timco Heavy Section screws, ideal for structural and exterior applications. Self-drilling design with EPDM washer for watertight sealing.
The **Timco Heavy Section Screws** provide high-strength fastening solutions for metal-to-metal applications.

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.
