HFH-0518-20ZI
High-Strength Studs - Type HFH/HFHS/HFHB - Unified
Our PEM® self-clinching studs provide a reliable fastening solution for high-strength applications in thin sheets. Easily installed with standard press equipment, these studs feature a flushhead design for a seamless finish. The HFH (heavy-duty) Studs offer enhanced pull-through resistance, making them a cost-effective alternative to weld studs. For superior electrical and mechanical attachment points, the HFHB (heavy-duty BUSBAR®) Studs, made of phosphor bronze, boast double the conductivity of carbon steel studs. With various types tailored for specific materials and hardness levels, including steel, aluminum, and copper, our studs ensure secure and durable fastening in a wide range of industrial applications. All finished with a zinc coating for corrosion resistance, they meet RoHS compliance standards, making them an environmentally friendly choice for your assembly needs.
