HFH-0420-28ZI
High-Strength Studs - Type HFH/HFHS/HFHB - Unified
Enhance assembly efficiency with our PEM® self-clinching studs, designed for easy installation in sheets through standard press application. Featuring high torque-out and pushout resistances, these studs securely lock into place, replacing weld studs for a more cost-effective solution. The HFH (heavy-duty) studs distribute axial tightening force over a broad area, improving pull-through resistance, while the HFHB (heavy-duty BUSBAR®) studs offer superior electrical/mechanical attachment points. With options for high-strength applications in various sheet materials, including steel, aluminum, and copper, these studs are versatile and reliable for a wide range of industrial needs. Explore our range of high-strength studs for efficient and durable assembly solutions.
