2 PM LF-LINHING NUT For load-bearing threads in thin sheets aluminum, steel, and other ductile materials. Proved Performance For over 6 years, PM brand self-clinching fasteners have satisfied production and fastening requirements wherever loadbearing threads are required in thin metal sections too thin to tap. Look for the PM trademarks Quick, convenient assembly using standard tools Installation of PM 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. The PM 3 Identification Marks Distortion-free installation Proper installation forces will not distort or damage the threads in PM nuts because the recommended shank length is always less than the minimum sheet thickness. Reverse side remains flush ll clinching takes place on the fastener side of the sheet. The reverse side remains flush and smooth. elf-clinching Locknuts These locknuts (Type L ) are designed with a unique and economical TRI-DNT locking feature, which meets demanding locking performance requirements. Thin heet elf-clinching Nuts These nuts (Type MP ) feature a lower profile and can be mounted closer to the edge of a sheet than standard self-clinching nuts. elf-clinching nuts for stainless steel PM 3 self-clinching nuts (Type P ) are especially designed for permanent installation into stainless steel sheets as thin as.3 /.8 mm. Machined from a specialty stainless steel, these fasteners are then heat-treated to a hardness higher than most 3 eries stainless steels. This feature enables PM 3 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. 44 ZI Type and Material Part Number Designation ode hank ode Finish Many PM self-clinching nuts meet NM45938/specifications. onsult our Marketing department for a complete Military pecifications and National erospace tandards guide (Bulletin NM) or check our website.
