Fastening the Suntuf Polycarbonate sheets is now easy. No pre-drilling, just insert the screw into the socket and away you go.

State of the art Clear Fix screws pre-drill their own hole in both the roof sheeting and the timber or metal support, then cut an oversized opening in the polycarbonate sheet to allow for expansion and contraction of the sheet then finish the whole thing off with a compressible neoprene washer flattening out to ensure a watertight fixture.

This length screw suits the Corrugated, Omega and Greca profile sheeting - 65mm length are required for the Trimdek profile roof sheet
