Nuts provide permanent load-bearing
threads
PEM self-clinching nuts provide permanent load-bearing threads in metal sheets too thin to be tapped and offer a practical alternative to extruded/tapped or stamped threads.
PEM self-clinching nuts provide permanent load-bearing threads in metal sheets too thin to be tapped and offer a practical alternative to extruded/tapped or stamped threads All-metal PEM nuts install quickly in sheets as thin as 0.64mm (depending on thread size), where they become a permanent and integral part of a component or assembly

Self-clinching nuts provide load-bearing threads
PEM self-clinching nuts provide permanent load-bearing threads in metal sheets too thin to be tapped and offer a practical alternative to extruded/tapped or stamped threads.
Their use minimises the amount of required fastening hardware, since only a mating screw is needed to complete the final attachment process.
PEM self-clinching nuts in steel, stainless steel, or aluminium are available in thread sizes 2-56 through 1/2-20 and M2 through M10, depending on type.
Families of PEM nuts have been developed for use in thin stainless sheets, ultrathin sheets, and with locking capabilities, among others.
PEM self-clinching nuts are easily installed by inserting the fastener in a punched or drilled hole, then applying a squeezing force using a Pemserter or other standard press to embed the nut's clinching ring completely in the sheet metal.
The clinching ring locks the displaced metal behind the tapered shank to promote high push-out resistance.
High torque-out resistance is achieved during installation when the nut's knurled platform is embedded in the sheet metal.
Proper installation forces will not distort or damage a PEM nut's threads.
All clinching occurs on the fastener side of the sheet, which allows the reverse side to remain flush and smooth.
