Self-Clinching Flush-Head Studs


PEM FHX self-clinching flush-head studs uniquely feature an X-Press thread profile enabling quick mating with push-on plastic nuts, wire tie products, or other plastic fasteners in thin metal assemblies. Their coarse thread design – larger threads relative to the stud’s diameter – reduces assembly time by allowing for easy mating of plastic parts and promotes especially high retention force. The thread design additionally accommodates paints and coatings without compromising fastener performance in service.


The studs install permanently in metal sheets as thin as 1mm. They press easily into place using any standard press or can be installed automatically during the stamping process using an automated PEMSERTER press equipped with in-die technology. Upon installation, the head of the stud mounts flush in the metal sheet for a clean and attractive finished appearance. Domed stud heads are available on special order.


The studs are manufactured from hardened carbon steel and finished with zinc plus clear chromate as standard or a rust-preventive oil finish as an option. They can be supplied in 5 or 6mm thread sizes and in lengths from 10 to 25mm.
