The PEM® SCBR™ spinning clinch bolt is a tool-only, self-retracting captive panel screw designed to permanently install into sheets as thin as 0.040 in (1.02 mm). The screw, made of hardened carbon steel with a zinc plating per ASTM B633, SC1, and the spring, made of 300 series stainless steel, are shipped together. It features an external thread of .138-32 UNF, mates with a #2 Phillips driver, and is suitable for panels with a hardness of HRB 80 or less or HB 150 or less. The minimum hole size is 0.138 in, with a minimum edge distance of 0.190 in. The screw retracts when disengaged and allows close centerline-to-edge installation.
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.
