Description

Stitching screws are designed for fixing metal roofing sheets together quickly and cleanly. The self-drilling point cuts through sheet metal up to 1.6mm thick without the need for a pilot hole, saving time on every fix. If you have ever spent half a morning drilling pilot holes across a roof, you will appreciate the difference.

How stitching screws work on metal roofs

Stitching screws sit in the raised ribs of profiled sheeting, pulling the overlapping sheets tightly together. Unlike through-fixings that go into purlins, these screws only join sheet to sheet. The tapered shank draws the two layers together as you drive the screw home, creating a secure mechanical connection without distorting the profile.

The hex head takes a standard 8mm socket or nut spinner, so you can run these in quickly with a drill or impact driver. On a decent-sized roof, that adds up to real time saved. The self-drilling point means one tool, one action, one fix no swapping between drill bits and drivers.

Where to use them

These screws suit agricultural buildings, industrial units, portal frame structures, and domestic outbuildings with profiled metal roofing or cladding. They work on galvanised steel, pre-painted steel, and aluminium sheets. Contractors fitting box profile, corrugated, or composite panel systems will find these a reliable everyday fixing.

For larger roofing contracts, buying in bulk keeps the cost per screw down and means fewer trips to the supplier mid-job.
