Captive Washers are used in conjunction with AccuGroup's Captive Screws to provide a permanent hold within an assembly. The washer is compressed during assembly to lock over the captive shank of the Captive Screw, preventing the screw from coming loose. The combination of Captive Screw and Captive Washer forms a cost effective locking solution for safety applications.
Captive Washers flatten during installation. This is intended to be a permanent fastening, as a Captive Washer is not suitable for re-use. For a lightweight and reusable variant of this component, please see AccuGroup's Retaining Nylon Washers range.
