Screws for fixing metal roofing. Three groups, each solving a different joint on the same roof.

Which group to choose

Farmer screws — the main fixing into structural timber: battens, purlins, rafters. Self-drilling point, sealing washer under the head
Stitching screws — sheet to sheet, in the overlap. Short, with a TORX® drive and an aluminium washer
Flange head — no drill point, for thin-walled profiles and flashings where the hole is already there or the material is thin enough to tap

Finish

All three groups can be supplied with heads powder coated to the colour of the roof — UV-resistant polyester, 50–60 µm. On a finished roof the fasteners stop being visible dots and become part of the surface.
