Captive Washers
Captive Washers are specialist retaining components designed to hold a screw or fastener in place within a panel, cover, or assembly, helping to prevent the loss of hardware during servicing, maintenance, or repeated access. Commonly used alongside captive screws, these washers allow the fastener to remain associated with the host component even when fully loosened, making them ideal for equipment covers, access panels, safety guards, and enclosure assemblies where loose screws are not desirable. Captive Washers are a practical solution for improving maintenance efficiency, reducing misplaced parts, and supporting a more controlled fastening system.
What are Captive Washers?
Captive Washers are retaining washers used as part of a captive fastening system. Once installed onto a compatible screw, they help keep the fastener fixed within the panel or housing so it cannot fall free after disengagement from the mating thread. This makes them especially useful in applications where panels need to be opened regularly for inspection or servicing, but where the fastener should remain attached to the assembly. They are commonly paired with captive screws across engineering, electronics, machinery, and industrial equipment.
