PennEngineering’s R’ANGLE fasteners for thin metal assemblies and PCBs create strong right-angle attachment points for tighter design control, reduced hardware counts and production economies for chassis, chassis to board or component to board applications. Self-clinching types install permanently into metal sheets and ReelFast SMT surface mount versions for printed circuit boards. The fasteners replace conventional bent edge tabs, bent centre tabs, bent flanges, angle brackets or tack welds.
Type RAA aluminum fasteners install in aluminum sheets as thin as .040 in. and accept thread-forming screws in sizes #4-40, #6-32, #8-32, and M3 and M4. Type RAS steel threaded fasteners install in aluminum or steel sheets as thin as .040 in. and are available in thread sizes #4-40, #6-32, #8-32, and M3 and M4.
A single mating screw completes the attachment process. Holding power of the fastener is unaffected by tightening or loosening of the screw.
The fasteners install at the edge or interior of boards (as thin as .040 in.) prior to the automated reflow solder process. Thread sizes for mating screws range from #2-56 through #8-32 and M2 through M4.
