Part # MSO4-256-4, PEM® Type MSO4™ Self-clinching microPEM® Standoffs

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.

¹ The “L” dimension is the height of the installed stud at max grip. The height of the stud will increase if it is installed into thinner material. To calculate “actual L” use this formula: max grip - actual grip + L = “actual L”
² To minimize sheet distortion and maximize product performance, use a centerline-to-edge value greater or equal to the value specified.
³ HRB - Hardness Rockwell “B” Scale. HB - Hardness Brinell
