PEM through hole threaded and unthreaded standoffs for mounting, spacing or stacking panels. SO SELF-CLINCHING STANDOFFSSELF-CLINCHING STANDOFFS PEM self-clinching standoffs, which use the proven self-clinching design, provide ideal solutions for applications where mounting, spacing or stacking of panels, boards or components are required. Pressed into round holes, these fasteners mount permanently into metal sheets as thin as .025 / 0.63 mm. Support This sheet Specially designed SO4, BSO4 and TSO4 standoffs are made from hardened stainless steel and are ideal for clinching into stainless steel sheets. An optional nickel plating is now available if product is expected to be used in a corrosive environment.
