The PEM® SCBR™ spinning clinch bolt with self-retracting feature is a tool-only, captive panel screw designed to permanently attach into sheet materials as thin as 0.040 in (1.02 mm), with the screw retracted by a spring when not engaged. It is available in a #8-32 thread size with a zinc-plated carbon steel screw and a 300 series stainless steel spring, compliant with ASTM B633, SC1 (5µm), Type III. The design allows for close centerline-to-edge installation and replaces loose hardware. Units are shipped with the mating spring included.
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.
