Patented PEMģ spinning clinch bolts for
thin metal panels have been introduced with a self-retracting feature enabling
the fastener's captive screw to remain retracted when disengaged.† During fastener installation, controlled
clinching action permanently captivates the retractable screw-and-spring
combination in the metal sheet and allows the screw to spin freely for quick
attachment of mating hardware. These fasteners can replace loose hardware and
serve as practical and economical alternatives to multi-component captive screw
PEM Type SCBRô spinning clinch bolts
can permanently captivate into aluminum or steel sheets as thin as .040 inch/1.02
mm (and greater) and can be specified for close centerline-to-edge
Installation is achieved by simply
pressing the fastener into a properly sized mounting hole and then applying
squeezing force on the top of the screw head and the underside of the sheet
material. The squeezing action forces the displacer of the screw into the
sheet, causing it to reduce the mounting-hole diameter and captivate the screw.
spinning clinch bolts with the self-retracting feature are available in various
lengths and thread sizes from #4-40 through #8-32 and M3 through M4.
Unlike industrial robots, which suffered a slight overall slump in 2012, service robots continue to be increasingly in demand. The majority are used for defense, such as unmanned aerial vehicles (UAVs); and agriculture, such as milking robots.
