The company’s 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 allows the side of the sheet opposite installation to remain smooth and untouched. The components install permanently in steel or aluminum sheets as thin as 1.6 mm. Studs (aluminum or stainless steel) are available in thread sizes #4-40 through #10-32 and M3 through M5 and in lengths from 0.25” through 1” and 6 mm through 25 mm. Standoffs (stainless steel) are offered in thread sizes #4-40 through 1/4-20 and M3 through M6 and in lengths from 0.187” through 1” and 4 mm through 25 mm. For more details, contact Michael J.
