Spinning Clinch Bolts Enable Captivated Screw to Spin
PEM spinning clinch bolts for use in thin metal sheets introduce one-piece captive screw solutions whose controlled clinching action during installation permanently captivates the screw while allowing it to spin freely in the sheet. This allows for quick attachment of mating hardware and reduced need for loose fasteners (such as screws and retaining clips or washers). These fasteners can serve as cost-effective alternatives to multi-component fastener assemblies.
The product line includes Type SCB fasteners with an unthreaded neck for axial float, Type SCBJ hardware integrating a jacking feature, and Type SCBR versions with a self-retracting feature enabling the captive screw to remain retracted when engaged. All permanently install into aluminum or steel sheets as thin as .040” / 1.02mm (and greater) and can be specified for close centerline-to-edge applications.
