Why Choose This Product

The fine thread profile grips metal studs securely, delivering superior pull-out resistance compared with coarse-thread alternatives on steel framing. The bugle head geometry allows the screw to countersink flush with the board surface in a single motion — no pre-drilling, no paper tear, and a smoother finish ready for jointing compound. The black phosphate coating adds a layer of corrosion resistance suited to clean, dry interior conditions. Supplied by Owlett Jaton, a trusted UK fastener distributor, these screws meet CE approval standards, giving specifiers and contractors confidence in compliance and consistency across the box.
