The SAMAC Hex Head Heavy Section Screws with 16mm Washer are high-strength, trade-grade fixings designed for heavy-duty roofing and cladding applications where secure fastening and long-term durability are critical. Ideal for fixing heavy-gauge steel sheets, cladding panels, and roofing materials, these screws are built to perform in demanding and exposed environments.
The hex head design allows for high-torque installation using impact drivers or socket tools, giving installers greater control and confidence during fixing. Each screw is supplied with an integrated 16mm washer, which helps distribute load evenly, reduce the risk of sheet damage, and improve sealing at the fixing point to minimise water ingress.
Supplied in a pack of 50, this size is ideal for smaller projects, repairs, or maintenance work where heavy-section performance is required without purchasing larger quantities. The SAMAC Hex Head Heavy Section Screws (50) deliver reliable strength, consistent results, and professional-grade performance trusted by trade users.
