2 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. PEM self-clinching standoffs are also available on special order in non-heat treated carbon steel as SON (thruhole threaded) or BSON (blind threaded). For more information on the proper use of PEM self-clinching standoffs, check our web site for Tech Sheet PEM - REF/Standoff Basics. s SO/SOS/SOA through hole threaded self-clinching standoffs for attachment and spacing of panels, boards or components - PAGE 3 s BSO/BSOS/BSOA Blind hole, threaded self-clinching standoffs for attachment and spacing of panels, boards or components where flush, closed end is required for smooth panel appearance - PAGE 4 s SO/SOS/SOA Through hole, unthreaded self-clinching standoffs for stacking and spacing multiple boards or panels - PAGE 5 s SO4/BSO4 ed blind hole, through hole threaded and unthreaded versions specifically designed for clinching into stainless steel sheets - PAGES 3 ( SO4) and 4 ( BSO4) s TSO/TSOS/TSOA Through hole threaded standoffs for clinching into thinner sheets than SO/SOS/SOA types.
