Fasteners for ultra-thin metal sheet
05 September 2013
PEM Type SMPS self-clinching nuts are suitable fasteners for ultra-thin metal sheet applications where design envelopes may be restrictive and space for attachment hardware may be limited.
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.
