Self-clinching Nuts

For over 60 years, PEM brand self-clinching fasteners have satisfied production and fastening requirements wherever load-bearing threads are required in thin metal sections too thin to tap.

Installation of PEM brand self-clinching nuts is simple, quick, and convenient. Just insert them in punched or drilled holes, then apply a squeezing force to embed the clinching ring completely in the sheet metal.

The clinching ring locks the displaced metal behind the tapered shank, ensuring high pushout resistance. High torque-out resistance is ensured when the knurled platform is embedded in the sheet metal.

Proper installation forces will not distort or damage the threads in PEM nuts because the recommended shank length is always less than the minimum sheet thickness.

All clinching takes place on the fastener side of the sheet. The reverse side remains flush and smooth.

These locknuts (Type SL^TM) are designed with a unique and economical TRI-DENT^® locking feature, which meets demanding locking performance requirements.

These nuts (Type SMPS^TM) feature a lower profile and can be mounted closer to the edge of a sheet than standard self-clinching nuts.

PEM 300° self-clinching nuts (Type SP^TM) are especially designed for permanent installation into stainless steel sheets as thin as .030"/ 0.8 mm.

Machined from a specialty stainless steel, these fasteners are then heat-treated to a hardness higher than most 300 Series stainless steels. This feature enables PEM 300 fasteners to be installed into stainless steel sheets, employing the same self-clinching principle which has proved successful over the years in thousands of applications.
