Description

25mm exterior stitching screws fix thin sheet metal to sheet metal quickly and securely. You do not need to pre-drill.

The self-drilling point cuts through thin metal with ease. This speeds up installation when fixing overlapping sheets.

Each screw has a hex head and EPDM washer. The washer compresses during installation and helps reduce water ingress. It also improves the seal between sheets.

The exterior silver organic coating protects against corrosion. This makes the screws suitable for outdoor and exposed conditions.

Key Features

  • Designed for stitching thin sheet metal together
  • Self-drilling point removes the need for pre-drilling
  • Hex head for strong drive and easy installation
  • EPDM washer helps reduce water ingress
  • Exterior coating improves corrosion resistance

25mm exterior stitching screws work well for overlapping metal sheets. They are commonly used in roofing, cladding, and external applications where extra grip is needed.
