Why Choose This Product

The fine thread profile delivers superior holding power in metal stud applications compared to coarse-thread alternatives, reducing the risk of board pull-through. The bugle head geometry allows the screw to sit perfectly flush — essential for a smooth skim coat finish. Supplied in a box of 1,000, this format suits trade use and reduces per-unit cost significantly. CE approval confirms the product meets European construction product standards, giving specifiers and contractors confidence on regulated sites.
