PennEngineering’s PEM X-Press self-clinching flush-head studs quickly mate with push-on plastic nuts or other plastic fasteners in thin metal assemblies. A coarse thread reduces assembly time and enhances retention force of the stud once it’s installed; and it also accommodates paints and coatings.

The studs, manufactured from hardened carbon steel, install permanently in metal sheets as thin as 1 mm, pressing easily into place using any standard press. The head of the stud mounts flush in the metal sheet for a clean and more attractive finished appearance compared with alternative methods, such as welding. The studs are finished with zinc and clear chromate to enhance rust prevention. They come with 5- and 6-mm threads, in lengths from 10 to 25 mm.
