High-Strength Studs - Type HFH/HFHS/HFHB - Unified
PEM® self-clinching studs offer a reliable and efficient installation method, perfect for high-strength applications in various materials. These studs are easily installed by pressing them into properly sized holes in sheets, creating a flushhead assembly with high torque-out and pushout resistances. Ideal for replacing weld studs, the HFH (heavy-duty) studs feature a large head that distributes tightening force over a wide area, improving pull-through resistance. For superior electrical/mechanical attachment points, the HFHB (heavy-duty BUSBAR®) studs, made of phosphor bronze, offer twice the conductivity of carbon steel studs. With different types available for specific material hardness, including steel, aluminum, and copper, these studs provide a versatile and durable solution for a wide range of applications.
