Self-Tapping Screws

Allen Self-Tapping Screws

Allen self-tapping screws feature an internal hexagonal socket drive that provides exceptional tool engagement and accommodates extremely high installation torques. The cylindrical socket head offers a minimal radial footprint, allowing installation in counterbored holes or spatially restricted mechanical recesses. The case-hardened threads effectively tap into robust alloys and dense polymers without thread shear. They are heavily relied upon in industrial machine tooling, compact hydraulic assemblies, and high-performance automotive component mounting.
