PennEngineering self-clinching flush-head studsPennEngineering says its PEM FHX self-clinching flush-head studs feature an X-Press thread profile that it’s claimed enables quick mating with plastic fasteners in thin metal assemblies. The company says the studs can be installed permanently in metal sheets as thin as 1mm. They press into place using any standard press or installed automatically during the stamping process using an automated PEMSERTER press equipped with in-die technology. Once installed, the head of the stud mounts flush in the metal sheet.

The company says 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 5mm or 6mm thread sizes and in lengths from 10mm to 25mm.
