Captive Screw Is also Known as Captive Panel Fasteners are designed to attach components to panels and thin sheet metal without the use of traditional joining methods such as welding. Also eliminate risks associated with loose hardware that could fall out and damage internal components. They prevent full removal of components, thus reducing the risk of damage whilst retaining access to an application. These fasteners are typically spring-loaded and supplied as multi-piece assemblies containing a Captive Panel Screw and a Captive Panel Retainer. This screw is installed by applying sufficient squeezing force using a press. The panel material is displaced and forced into the undercut and around the knurled self-clinch feature. This prevents movement and rotation for a secure join. No additional hole preparation is required.
