PEM® concealed-head self-clinching studs and standoffs can be permanently mounted in steel or aluminum sheets as thin as .062"/1.6mm to provide strong and reliable threads for attachment applications. These fasteners further promote flush assemblies due to their concealed-head capability, which allows the side of the sheet opposite installation to remain smooth and unaffected by the fastening process.
PEM self-clinching aluminum or stainless steel threaded 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. PEM self-clinching stainless steel threaded 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.
Sheet preparation for their installation requires only a blind milled hole to the recommended minimum depth. Using a PEMSERTER® press for best results, the fasteners can be placed in the holes and then simply squeezed with sufficient force. Upon installation, the fastener head is locked securely in the sheet and able to handle substantial loads. Mating hardware completes final attachment of components in the assembly.
