PEM® SCBR™ spinning clinch bolt with self-retracting feature permanently captivates into sheets as thin as 1.02 mm and retracts when disengaged. It installs without loose hardware and permits close centerline-to-edge applications. The screw is hardened carbon steel with zinc plating per ASTM B633, SC1, and the spring is 300 series stainless steel. Mating springs are included. Thread size is M3 x 0.5, with a 12 mm length code. Minimum hole size is 3 mm, minimum distance to sheet edge is 4.5 mm, and a #1 driver is required.
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.
