Captive Panel Screws
Often found in PC boards and equipment panels, captive panel screws are frequently used when mounting hardware. Captive panel screws are identified by their unthreaded shanks and threaded ends, and can be combined with washers, springs and retaining rings and washers in various assemblies. Captive panel screws and fasteners are particularly useful when fastening components where vibration, thermal conductivity and expansion, and shock are factors. They also allow for quick panel removal and reinstallation.
