Why Choose This Product

The fine thread profile grips metal studs securely without stripping, while the bugle head profile eliminates over-driving and board damage — a critical advantage on taped-and-jointed finishes. Collated strips are compatible with all major auto-feed gun brands, keeping productivity high on site. CE approval provides assurance of conformity for commercial and regulated projects. Buying in a 1,000-box quantity delivers strong cost-per-fixing value for trade users.
