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.

  • 1 The “L” dimension is the height of the installed stud at max grip. The height of the stud will increase if it is installed into thinner material. To calculate “actual L” use this formula: max grip - actual grip + L = “actual L”
  • 2 To minimize sheet distortion and maximize product performance, use a centerline-to-edge value greater or equal to the value specified.
