Timco Hex Head Self-Drilling Screws 5.5x100mm, 100pc (A2-304 Stainless Steel)
100 self-drilling screws for roofing (5.5x100mm). A2-304 stainless steel with EPDM washer. No pre-drilling required for steel up to 5mm.
These Timco Hex Head Self-Drilling Screws provide reliable fastening for joining roofing sheets to light section steel (up to 5.0mm thickness) without the need for pre-drilling. Their bi-metal construction combines a hardened carbon steel drill tip with an A2-304 austenitic stainless steel body, offering excellent corrosion resistance and durability for exterior applications.
The fixed EPDM washer ensures a weatherproof seal, preventing leaks at the fixing point. These screws feature a No.3 self-drilling point for easy penetration into steel, saving time on installation. The hex head design (8mm socket size) allows for secure tightening using standard tools.
Ideal for roofing and cladding applications, these screws are particularly suited for exterior use where corrosion resistance is required. The organic silver coating provides additional protection while maintaining an aesthetically pleasing finish.
