Installing permanently in steel or aluminum metal sheets as thin as 0.64mm, their minimal 'edge of sheet' to 'centre of fastener' distance (3.7mm) enables close-to-edge mounting on a panel and a small diameter (5.6mm) and low height (1.4mm) combine for an overall low-profile fastener system.
These self-clinching nuts provide strong, durable, and reusable metal threads to accommodate a mating screw, which completes the assembly and eliminates any need for additional attachment hardware.
A serrated clinching ring prevents the fastener from rotating after installation. In service these nuts ultimately will not loosen, fall out, or otherwise adversely affect end-product integrity or performance.
PEM Type SMPS nuts are made from 300 Series stainless steel and can be supplied in unified or metric thread sizes #2-56 through #6-32 and M2.5 through M3.5.
As a value-added option for specification when hardware must be installed prior to painting or similar operations, a PEM Blu-Coat thread mask can be applied in advance.
During assembly, threads of the mating hardware will remove paint, electro-deposited automotive undercoats, or weld splatter upon application of torque.
