PennEngineering® says its PEM® Type SMPP™ self-clinching nuts install permanently in ultra thin stainless steel sheets and provide dimensionally ideal solutions for stainless assemblies where space for attachment hardware may be limited.
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 M2.5 through to M3.5.
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 impact the end product integrity or performance.
A minimal footprint, resulting from an overall low profile design, combines low height (0.065 inches/1.4mm) and small diameter (0.220 inches/5.6mm) with close to edge mounting capabilities for installation in stainless steel sheets as thin as 0.025inches/0.64mm. Their corrosion resistance will be similar to 300 Series stainless steel.
