Clinch Fastener Solutions

PennEngineering's PEM self-clinching concealed-head studs and standoffs install permanently in steel or aluminum sheets as thin as .062” / 1.6mm to provide strong and reusable threads for mating hardware in a wide range of thin-metal assembly applications. Their concealed-head feature allows the side of the sheet opposite installation to remain smooth and sealed from air, liquid, dust and gases. The aluminum or stainless steel studs are available in thread sizes #4-40 through #10-32 and M3 through M5 and in lengths from .250” through 1” and 6mm through 25mm. Stainless steel standoffs are offered in thread sizes #4-40 through 1/4-20 and M3 through M6 and in lengths from .187” through 1” and 4mm through 25mm. These fasteners are RoHS-compliant and some stud types meet NASM63540 specifications.
