Retaining Washers
Retaining Washers feature internal fins, which grip the thread of a fasteners, creating a self-retaining fastening. Retaining Washers are designed for use with Captive. The combination of Captive Screw and Retaining Washer creates a lightweight and cost-effective locking solution for safety applications.
A Plastic Retaining Washer is primarily used to hold screws and bolts in place during assembly and have a design that grips the outside of screw or bolt shank. Also known as an Anti Loss Washer, they provide insulation, cushioning and spacing. They help insulate fastening assemblies from moisture and electricity.
This washer range includes options with internal and external teeth with a tapered design. The washer slides/assembles on to the screw (or bolt) and is retained by the screw once assembled. The washer cold forms and fully enters the pitch of the screw to provide sealing.
These washers allow for preliminary mounting of the screw (or bolt) before securing with a nut. They are ideal when pre-assembly of the screw and washer is required.

- Sliding surfaces allow tightening with damaging the mating surfaces.
- High resistance to vibration due to positive locking of the serrations
- Suitable for a wide range of screw/bolt heads minimizing stocks.
