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.
This year, Design News is getting a head start on the Fourth of July celebration. In honor of our country and its legacy of engineering innovation -- in all of its forms -- we are taking you on an alphabetical tour through all 50 states to showcase interesting engineering breakthroughs and historically significant events.
Earlier this year paralyzed IndyCar drive Sam Schmidt did the seemingly impossible -- opening the qualifying rounds at Indy by driving a modified Corvette C7 Stingray around the Indianapolis Motor Speedway.
