New PEM® Type SMPP™ Self-Clinching Nuts Install with Minimal Footprint in Ultra-Thin Stainless Steel Sheets

New PEM® Type SMPP™ self-clinching nuts from PennEngineering® install permanently in ultra-thin stainless steel sheets and provide dimensionally ideal solutions for stainless assemblies where space for attachment hardware may be limited. A minimal footprint resulting from an overall low-profile design combines low height (.065” / 1.4mm) and small diameter (.220” / 5.6mm) with close-to-edge mounting capabilities for installation in stainless steel sheets as thin as .025” / 0.64mm. Their corrosion resistance will be similar to 300 Series stainless steel.

Upon installation, a serrated clinching ring prevents the nut from rotating in service and, ultimately, the fasteners will not loosen, fall out, or otherwise adversely affect the end-product integrity or performance.

PEM Type SMPP nuts are made from age-hardened A286 stainless steel and recommended for use in stainless sheets with hardness of HRB 90 / HB 192 or less. Thread sizes for mating hardware range from #2-56 through #6-32 and M2.5 through M3.5.

Detailed specifications, fastener drawings and models, and performance data (Bulletin SMPP) for these RoHS-compliant fasteners can be accessed at www.pemnet.com
