Spinning Clinch Bolts Have Self-Retracting Feature
PEM Type SCBR spinning clinch bolts can permanently captivate into aluminum or steel sheets as thin as 0.04 in. (and greater) and can be specified for close centerline-to-edge applications.
Installation is achieved by simply pressing the fastener into a properly sized mounting hole and then applying squeezing force on the top of the screw head and the underside of the sheet material. The squeezing action forces the displacer of the screw into the sheet, causing it to reduce the mounting-hole diameter and captivate the screw.
