What are Captive Push-On Washers ?

Captive Push-On Washers are commonly used to create a permanent hold within an assembly, for example acting as a Retaining Washer to secure a screw onto a panel.

Captive Push-On Washers can often be used in conjunction with a Captive Screw to create a cost effective locking solution, with the washer preventing the screw from coming loose and thereby reducing the risk of fastener loss on production and assembly lines.

For applications where captive fasteners are required to be fitted to equipment such as safety guards, Captive Push-On Washers can be used to achieve compliance with EU machine Directive 2006/42/EC.

This type of washer is intended to be a permanent fastening, and is therefore not suitable for re-use.

For a lightweight and reusable variant of this component, please see Accu's Retaining Nylon Washers range.


Accu’s Captive Push-On Washers are manufactured from austempered carbon steel, with a bright zinc plated finish to provide a barrier against corrosion and are also available in a black phosphate and oil finish.
