PennEngineering's new PEM® micro self-clinching standoff
fasteners can serve as practical, cost-effective, and permanently secure
solutions enabling quicker assembly of devices ranging from hand-held consumer
electronics to medical equipment, among others.
PEM Type MSO4™ micro
self-clinching standoffs are manufactured from 400 Series stainless steel and
are engineered with threads as small as M1.0 / #00 and in lengths as short as 2
mm / .080 inch. They can be installed into sheet metal (including 300 Series
stainless steel) as thin as 0.4 mm / .016 inch with maximum hardness up to HRB
88 on the Rockwell "B" scale.
The micro standoffs clinch permanently
into place by pressing them into a properly sized mounting hole using a punch
and anvil until the fastener's head is flush with the sheet. Upon installation,
they become a permanent part of an assembly, will not loosen or fall out, and
provide strong and reusable load-bearing threads. Installing them automatically
can further reduce costs by accelerating production and eliminating any need to
handle the small parts.
