Self-clinching concealed-head studs and standoffs
PEM self-clinching concealed-head studs and standoffs provide strong, permanent, and reusable threads for mating hardware in thin-metal assembly applications. Their concealed-head feature offers design and aesthetic benefits by allowing the side of the sheet opposite installation to remain smooth and untouched. This feature additionally serves as a solution for applications where the host metal sheet must remain completely sealed from air, liquid, dust, gases, or other potential contaminants.Concealed-head studs and standoffs install permanently in steel or aluminum sheets as thin as .062-in/ 1.6mm. Studs (aluminum or stainless steel) are available in thread sizes #4-40 through #10-32 and M3 through M5 and in lengths from .250-in through 1-in and 6mm through 25mm. Standoffs (stainless steel) are offered in thread sizes #4-40 through 1/4-20 and M3 through M6 and in lengths from .187-in through 1-in and 4mm through 25mm.
Sheet preparation for their installation requires only a blind milled hole to the recommended minimum depth. Using a PEMSERTER or other standard press, installation is quick and easy by placing the fastener in the hole and applying sufficient squeezing force. The fastener head then locks securely in the sheet and can handle substantial loads.
These fasteners are RoHS-compliant and some stud types meet NASM63540 specifications.
