Buildex 12G x 20mm Class 4 metal cladding TEKS screws with seal are self-drilling fasteners for fixing metal cladding and fencing to light-gauge steel. The heavier 5.5mm diameter shank gives strong holding, and the TEKS point drills through metal without pre-drilling.
The sealing washer helps close the fixing point, and Class 4 corrosion protection makes these suited to exposed, weathered and coastal cladding and fencing. The hex head drives with a standard nut driver for high torque.
