PEM® CONCEALED-HEAD STUDS AND STANDOFFS
INSTALL PERMANENTLY AND PROMOTE SMOOTH
DESIGNS

PEM® self-clinching concealed-head
studs and standoffs install permanently in steel or aluminum sheets as thin as
.062” / 1.6mm to provide strong and reusable threads for mating hardware in a
wide range of thin-metal assembly applications.
Their concealed-head feature contributes particular design benefits by
allowing the side of the sheet opposite installation to remain smooth and
untouched. This
feature additionally serves to satisfy applications where the sheet must remain
completely sealed from air, liquid, dust, gases, or other potentially
infiltrating elements.
The aluminum or stainless steel
studs are available in thread sizes #4-40 through #10-32 and M3 through M5 and
in lengths from .250” through 1” and 6mm through 25mm. Stainless steel
standoffs are offered in thread sizes #4-40 through 1/4-20 and M3 through M6
and in lengths from .187” through 1” and 4mm through 25mm.
Sheet preparation for their
installation requires only a blind milled hole to the recommended minimum
depth. Using a PEMSERTER® or
other standard press, installation is accomplished by placing the fastener in
the hole and applying sufficient squeezing force. The fastener head then locks securely in the
sheet and can handle substantial loads.
