- • Holding Power: Self-drilling point and timber-thread engagement create secure connections for roofing panels
- • Best for: Roofing installers joining metal panels to timber frame buildings
- • Not ideal for: Applications involving steel thicker than 1.2mm or non-timber substrates
Designed for joining metal roofing panels to timber frame buildings using a self-drilling T17 Gash Point. Complete with 16mm EPDM rubber washers and rated for steel thicknesses 0.5-1.2mm.
Faster installations - thanks to the self-drilling T17 Gash Point
The T17 Gash Point forms its own pilot as it is driven, cutting into the metal and timber without a separate drilling step. The design displaces material and creates a thread for the screw to bite rapidly.
Reduce labour time on long roof runs by removing the need to pre-drill in most common situations, speeding up installation.
Weatherproof jointing - with a 16mm EPDM rubber washer
A 16mm EPDM washer sits beneath the screw head and compresses against the panel surface when tightened, creating a sealing interface between metal and timber. EPDM is resilient to weathering and maintains elasticity.
Helps prevent water ingress around fixings, giving more reliable seals at laps, ridges and eaves.
Matched to common panels - thanks to suitability for 0.5-1.2mm steel
Screws are specified for use with steel panels between 0.5mm and 1.2mm thickness, covering a broad range of standard roofing sheets. Compatibility avoids under- or over-penetration that can compromise joints.
Choose these screws when using standard-profile metal roofing to ensure correct engagement and dependable fastening.
