Self Clinching Bolts Stainless Steel Flush Head Passivated Pressure Rivet Screws

Self clinching bolts or PEM studs use the proven self-clinching design, install with a squeeze in punched or drilled round holes, and become permanently mounted in the thin sheet; Thread sizes #2 to #3/8″ and M3 to M10. Self-Clinching studs are pressed into a hole in a sheet to be installed, this embeds the head of the stud creating a secure lock into the sheet with high torque-out and pushout resistances. Ever Hardware provides custom-made fasteners and customizable packaging.

PEM self-clinching studs are installed by placing them in properly sized holes in the sheets and squeezing them 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 for sheet thickness of 1.00mm and 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.

Heat treating makes the self-clinching bolts high tensile. Heat treating is a group of industrial and metalworking processes used to alter the physical, and sometimes chemical, properties of a material. The most common application is metallurgical.
