Item # CLSS-M5-2

Strong internal threads in sheets as thin as .030" / 0.8 mm. Thread sizes #2 to 1/2"and M2 to M10.

For load-bearing threads in thin sheets - aluminum, steel, and other ductile materials.
  • Proved Performance
    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.
  • Quick, convenient assembly using standard tools
    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.
  • High pushout & torque-out resistance
    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.
  • Distortion-free installation
    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.
  • Reverse side remains flush
    All clinching takes place on the fastener side of the sheet. The reverse side remains flush and smooth.
  • Self-clinching Locknuts
  • These locknuts (Type SL™) are designed with a unique and economical TRI-DENT® locking feature, which meets demanding locking performance requirements.
  • Thin Sheet Self-clinching Nuts
    These nuts (Type SMPS™) feature a lower profile and can be mounted closer to the edge of a sheet than standard self-clinching nuts.
  • Self-clinching nuts for stainless steel
    PEM 300® self-clinching nuts (Type SP™) 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.
