Description
Heavy section self drilling screws 100mm provide a fast and reliable fixing into steel without pre-drilling. The No.5 drill point cuts through steel up to 12mm, so installation stays quick and efficient on site.
In addition, the partially threaded design improves clamping performance. The metric thread with V flutes and torque-reducing slash helps drive the screw smoothly while reducing resistance. As a result, you get a tighter and more controlled fixing into heavy section steel.
Each screw also includes an EPDM washer. This forms a watertight seal at the fixing point, which makes these screws suitable for roofing, cladding, and other external applications. The exterior silver organic coating further protects against corrosion and performs well in urban and industrial environments.
