HFH-0518-28ZI
High-Strength Studs - Type HFH/HFHS/HFHB - Unified
Our PEM® self-clinching studs are designed for easy installation in sheets, providing secure attachment points with high torque-out and pushout resistances. These HFH (heavy-duty) studs offer a cost-effective alternative to weld studs, featuring a large head that distributes tightening force for improved pull-through resistance. HFHB (heavy-duty BUSBAR®) studs, made of phosphor bronze, excel in electrical applications. With options for high-strength steel, aluminum, and copper sheets, these studs are versatile and reliable for various industrial needs. Watch our animation for a visual guide on installation. Rest assured, these studs are RoHS compliant for environmental safety.
