Captive Panel Screws & Retainers
Captive screws are a type of screw typically used in PC boards and equipment panel assemblies where mounting hardware is subject to loss. Identifiable by the unthreaded shank with a threaded end, captive screws are often combined with washers, springs, and retainers depending on their intended function, to create a self-captivating assembly. They are especially useful for fastening applications where thermal conductivity, vibration, shock and thermal expansion are a factor, or where panels must be removed/reinstalled on the fly with speed and efficiency. Precision machined captive screws are often found in military, medical, electronic and industrial applications where tight tolerances and high quality and reliability are a factor.
