Patented PEM “Type DSOS” self-clinching threaded standoffs can be installed close to edges in thin metal sheets and offer a reliable method to stack or space components in an assembly. They can serve ideally where space for fastening hardware may be limited and are RoHS compliant. These stainless standoffs (steel types can be ordered) provide strong and reusable metal threads to provide secure attachment and enable component disassembly when required. They are available in two lengths and in thread sizes #4-40 and M3. The standoffs can be installed flush in steel or aluminum sheets as thin as 0.94 mm and with minimum centerline-to-edge distances of 3.2 mm.
