PEM self-clinching studs are installed by placing them in properly sized holes in the sheets and squeezing into place with any standard press. The squeezing action embeds the head of the stud into the sheet. The metal displaced by the head flows smoothly and evenly around the ribs and into the annular groove – creating a flushhead assembly and securely locking the stud into the sheet with high torque-out and pushout resistances.

FH (flush-head) studs are available in aluminum, steel, or stainless steel. They are also available unthreaded on special order.

• Flush-head in designated minimum sheet thickness or greater.
• Type FH is recommended for use in steel or aluminum sheets HRB (Rockwell “B” scale) 80 or less and HB (Hardness Brinell) 150 or less.
• Type FHS is recommended for use in steel or aluminum sheets HRB (Rockwell “B” scale) 70 or less and HB (Hardness Brinell) 125 or less.
• Type FHA is recommended for use in aluminum sheets HRB (Rockwell “B” scale) 50 or less and HB (Hardness Brinell) 82 or less.

Standoffs & Spacers

Screws & Fasteners NUT, FLUSH, STAINLESS

PEMSERT self-clinching flush nuts are designed to be completely flush in sheets as thin as 1.5mm.

These fasteners are ideal for applications where a thin sheet requires load-bearing threads but still must remain smooth, with no protrusions on either surface. The PEM flush nut can be installed easily by squeezing it into a round hole in metal sheets. When the fastener is installed, both the top and the bottom of the sheet remain smooth, enhancing the functional and cosmetic qualities of the entire assembly. PEMSERT self-clinching flush nuts can be installed in metal sheets before bending and forming. This can provide strong threads in places which would be inaccessible for installation after chassis are formed.

The hexagonal head along with the proven PEM self-clinching design ensures high axial and torsional strength and PEMSERT Type F fasteners can be ordered to conform to US NASM45938/4 specifications.

Self-Clinching Nuts

PEM CLA/CLS/CLSS Self-Clinching Nuts offer simple, press-in installation and provide load-bearing threads in thin sheets with high pushout and torque-out resistance. The nuts are installed by placing them into properly sized holes in sheets and applying a parallel squeezing force to the head of the nut. The sheet metal surrounding the head cold flows into an undercut, making the fastener an integral part of the sheet. The serrated clinching ring prevents the fastener from rotating after installation. The CLA series is compatible with aluminum anodizing and recommended for use in steel or aluminum sheets HRB 50 / HB 82 or less. The CLS/CLSS series are recommended for use in steel or aluminum sheets HRB 70 / HB 125 or less. PEM CLA/CL/CLSS Self-Clinching Nuts are non-magnetic and corrosion-resistant.

Features:

• Simple, press-in installation
• Installs permanently in aluminium, steel, or stainless steel sheets
• Strong load-bearing threads in thin sheets
• High pushout and torque-out resistance
• Serrated clinching ring prevents the fastener from rotating after installation
• Available with prevailing torque or free-running locking threads
• Superior corrosion resistance
• Non-magnetic
• CLA series is compatible with aluminum anodizing and recommended for use in steel or aluminium sheets HRB 50 / HB 82 or less
• CLS/CLSS series are recommended for use in steel or aluminum sheet HRB 70 / HB 125 or less
