Timco heavy section self-drilling screws (5.5x38mm) with EPDM washers for metal-to-steel fixing. 100pc pack - no pre-drilling needed.
The Timco Heavy Section Self-Drilling Screws are premium fasteners designed for attaching metal to heavy section steel (maximum 12mm thickness) without the need for pre-drilling. These screws feature a durable exterior plating with silver organic coating that provides exceptional corrosion resistance, tested to withstand 500 hours of salt-spray exposure - making them ideal for exterior applications.
These hex-head screws come with an integrated EPDM washer that creates a weather-tight seal. The hardened carbon steel construction ensures superior strength and durability, while the No.5 self-drilling point allows for easy installation in heavy gauge steel sections. The 8mm socket size provides positive driver engagement during installation.
With an effective thread length of 16mm, these screws offer optimal holding power. They're particularly suitable for construction projects where robust fixing to thick metal sections is required, including metal roofing, cladding applications, and structural steel work.
