Concealed-head self-clinching studs and standoffs can be mounted permanently in steel or aluminum sheets as thin as 0.062 in. These stud and standoff fasteners promote flush assemblies due to their concealed-head capability, which enables the side of the sheet opposite installation to remain smooth and unaffected by the fastening process.
