Weatherproof Timco self-drilling screws (5.5x38mm) with EPDM washer. Ideal for roofing & steel constructions.
The Timco Metal Construction Light Section Screws are high-quality, self-drilling fasteners designed for joining roofing sheets to light section steel (up to 5.0mm thick) without the need for pre-drilling. These screws feature a hex head for easy installation and a built-in EPDM washer to provide a secure, weatherproof seal.
Constructed from case & core hardened carbon steel, these screws are exceptionally durable and resistant to wear. The exterior plating (silver organic) offers superior corrosion resistance, withstanding 500 hours of salt-spray testing – making them ideal for outdoor applications where weatherproofing is essential.
