FORGEFIX Stitching Screw TFHW16SD6325 Pack of 100

Faster installation with a self-drilling point for efficient on-site work

The self drilling point on the stitching screw cuts its own pilot hole in many thin metals and composite panels, reducing the need for separate drilling and saving installation time. This faster fixing method supports tighter schedules on roofing and cladding projects. The bolt-like action combined with the 6.3 mm diameter ensures a firm hold without excessive torque requirements.

A watertight seal that protects the fastening and surrounding material

An integrated 16 mm EPDM washer provides a reliable seal between head and surface, preventing water ingress at the fixing point. The 8 mm head size distributes load over the washer, limiting local deformation and keeping cladding and sheet joints neat and secure. The visible silver finish maintains a discreet appearance on light-coloured surfaces.
