PEM Type SCBR™ Spinning Clinch Bolt installs by simply pressing it into a properly sized hole. The controlled clinching action permanently captivates the screw and spring in the panel and allows the screw to spin freely in the sheet.

Features and Benefits
  • Permanently captivates into sheets as thin as .040” / 1.02 mm.
  • Spring keeps screw retracted when disengaged.
  • Provides economical self-retracting captive screw.
  • Replaces loose hardware.
  • Allows for close centerline-to-edge distance.
  • RoHS compliant.
Type SCBR screws are shipped with mating springs.
