Raised Countersunk AB Self Tapping Screws

Our Raised countersunk AB self-tapping screws are precision fasteners designed for flush-fitting applications where a slightly domed finish is preferred. The raised countersunk head offers a clean, low-profile appearance while providing additional bearing surface compared to standard countersunk screws—ideal for materials prone to deformation or cracking.

These screws feature the AB thread form, combining the sharp point of Type A with the finer pitch of Type B, enabling efficient thread formation in sheet metal, plastics, and other soft substrates without the need for pre-drilling.
