Product Overview
The solar hanger bolt is the standard fixing point for metal roof PV: a self-tapping SUS304 screw drills through the sheet crown into the purlin, while the bonded EPDM washer seals the penetration. The integrated L-foot accepts rail and T-bolt hardware.
Supplied with allen-key hex head and pre-applied thread sealant on request. Tensile and pull-out values are tested per EN 14592; each batch ships with material certificates.
