PEM® brand self-clinching blind fasteners provide permanently mounted blind threads in metal sheets as thin as .040”.
  • Provides barrier to protect threads against foreign matter.
  • Protects internal components from intrusion of screws.
PEM blind fasteners employ the proven PEM self-clinching design and are easily installed in properly sized holes. Shanks of PEM fasteners act as their own pilots. PEM blind fasteners can be installed with any standard press applying squeezing forces between parallel surfaces.

PEM self-clinching blind fasteners are available in thread sizes from #4-40 through 1/4-20 in carbon or stainless steel.
