Buildex Cladding & Fencing Screws are 12G x 20mm Class 4 self-drilling TEKS fixings with a sealing washer, supplied in a 500-pack trade box.
The TEKS self-drilling point bores into steel without a pilot hole and the seal helps resist water, suiting metal cladding and fencing fixed to steel sections.
Buildex 12g x 20mm Class 4 Cladding Fencing Teks Screws with Seal 500 Pack are self-drilling fasteners designed for securing metal cladding and fencing to light-gauge steel.
These screws feature a TEKS® self-drilling tip that easily cuts through metal, eliminating the need for pre-drilling and saving time during installation. With Class 4 galvanisation, they provide exceptional long-term corrosion protection, making them suitable for severe external environments and structural applications exposed to weather or coastal conditions. The hex head design allows for higher torque transfer, ensuring secure tightening and compatibility with standard wrenches or sockets. Designed for exterior use, these screws deliver strong and reliable fixing into metal, ensuring long-lasting performance outdoors. This pack contains 500 screws, each measuring approximately 5.5mm in diameter and 20mm in length.
