PEM® brand self-clinching blind fasteners provide
permanently mounted blind threads in metal sheets as
thin as .040” / 1 mm.
➣ Provides barrier to protect threads against foreign
matter.
➣ Protects circuits from intrusion of extra long
screws.
PEM blind fasteners employ the proved PEM self-
clinching design and are easily installed in drilled or
punched 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. Installation is inexpensive and requires
no previous skills or experience.
Part Number Designation
PEM self-clinching blind fasteners are available in thread
sizes from #4-40 through 1/4-20 / M3 through M6 in
B – 832 – 2 ZI
carbon or stainless steel. PEM blind fasteners in each
thread size are available in two different shank lengths
to meet the specifications of design engineers who want
panel holes refilled as much as possible. Type and Thread Shank Finish
