Retaining Washers

 (1 product group)

Retaining washers, also known as captive washers, are specifically designed to be used alongside captive screws to create a self-retaining fastening which locks in place after installation. This allows for simple and secure fixing in applications where a captive style screw is required. They are designed to cover up the head of a screw as it passes through a manufactured hole or in a drilled hole to prevent the screw from backing out or coming loose. They help provide maximum security and fixity of screws in various applications.


Retaining Washers

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 easily slides 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. They also help reduce assembly time and cost.

The range includes material options that provide corrosion, abrasion and chemical resistance.
