PEM® HIGH TENSILE STRENGTH STUDS
OFFER
SUPERIOR THREAD STRENGTH AND HARDNESS

New PEM® high
tensile strength studs provide robust fastening solutions for the most
demanding applications requiring superior thread strength and hardness. These Type HFG8™ (unified) and Type HF109™
(metric) clinch studs are specially heat-treated to achieve greater tensile
strength up to Grade 8 (unified) and Property Class 10.9 (metric) meeting 150
ksi/1040 MPa minimum. Their
large-diameter heads serve to reduce compressive stress on panels and promote
development of full thread strength.
These carbon alloy steel
studs have been introduced in thread sizes up to 5/16-18 / M8 and in lengths up
to 1” / 25mm. (Longer
lengths can be specially ordered.) Appropriate sizes of
the Grade 8 and Property Class 10.9 products meet SAE J429 and ISO 898-1/SAE
J1199 specifications, respectively. They
additionally carry the appropriate head markings.
The studs install permanently in carbon steel or HSLA
steel sheets as thin as .040” / 1.5mm with hardness up to HRB 89 on the
Rockwell “B” scale. Installation is
accomplished easily (without welding) using standard punch and anvil or
automated equipment. The studs enable
reliable, secure, and simplified attachment of components or assemblies with
only a mating nut necessary to complete the process.
