Flat Roofing and Decking screws are used in a variety of applications. BS screws mostly fasten insulation or weatherproofing membranes to metal decks.
- Carbon steel is the most popular material for fixings as it is strong, weather resistant and affordable.
- The bugle head has a torx 25 drive, ensuring easy installation.
- The coarse thread provides excellent engagement with the steel, maximising pull-out values.
- BS Screws can be used with plastic tube washers and decking plates, which we also supply.
For maximum fastener performance, we recommend using a tek screw driver which does not exceed 2500RPM.
