This is a 12?gauge x 85 mm, hex-head, self-drilling roof screw with a Type-17 point, designed for fixing steel roof sheeting to timber battens or trusses. Drills through metal into timber without the need for a pilot hole—ideal for securing roofing to timber substrates. Long enough to penetrate typical roofing and timber layers securely. Provides a tight seal against the roof surface, guarding against water ingress and ensuring a flush finish.
