PEM Type MSO4 self-clinching microPEM® standoffs are used to stack or space internal components and provide strong, permanent, and reusable load-bearing threads in metal sheets as thin as .012” / 0.3mm. Thread sizes have been developed as small as M1 and available unified fastener lengths are .094” and .125” and 2mm and 3mm in metric.
  • Become integral parts of an assembly by clinching permanently in place.
  • Will not loosen or fall out.
  • Can be installed into stainless steel sheets.
  • Can be installed automatically.
  • RoHS compliant.
