GSE Short 45mm Silver Screw - Self Tapping Screw with EPDM Washer
The GSE ART105988 is a short-version self-tapping screw (45mm instead of standard 60mm) made from A2 stainless steel with integrated EPDM washer. Specifically designed for fixing GSE frames and trays to roofs without counter-battening, this shorter screw prevents the risk of screwing through a single batten into the roof felt - an increasingly common requirement in UK installations.
