PEM® R'ANGLE® Fasteners for Thin Metal or PC Board Assemblies Create Permanent Right-Angle Attachment Points


The expanded family of patented PEM® R'ANGLE® fasteners provide efficient and reliable methods to create permanent right-angle attachment points in thin metal assemblies or printed circuit boards. The product line includes self-clinching types for installation in thin metal sheets and ReelFast® SMT surface mount fasteners for use with printed circuit boards.

The R'ANGLE clinch fasteners for metal applications offer cost-effective alternatives to bent tabs at edges of sheets, bent tabs in the middle of sheets, bent flanges, right-angle brackets, or tack welds. The R'ANGLE SMT versions for board applications can eliminate the need for conventional angle brackets or threaded right-angle blocks. All can reduce hardware counts in an assembly, promote lighter designs, and streamline production.

For metal assemblies Type RAA(TM) aluminum clinch fasteners install in aluminum sheets as thin as .040" / 1mm and accept thread-forming screws in sizes #4-40, #6-32, #8-32, and M3 and M4. Type RAS(TM) steel threaded fasteners install in aluminum or steel sheets as thin as .040" / 1mm and are available in thread sizes #4-40, #6-32, #8-32, and M3 and M4. A single mating screw completes component attachment.

The ReelFast SMT fasteners can serve to mount board to chassis, chassis to board, or component to board. They install at the edge or interior of boards (as thin as .040" / 1mm) in the same manner and at the same time as traditional surface mount components prior to the solder reflow process. Thread sizes for mating screws range from #2-56 through #8-32 and M2 through M4.
