Retaining Washers

In stock

Retaining Washers, also known as Retention Washers or Anti-Loss Washers, are fasteners that are designed to lock in place after installation - creating a secure fastening assembly. The are designed so the inside diameter grips the outside of a screw shank. The washer easily slides on to screw, but is retained on the screw once assembled.

Our retainer washer range includes a selection of nylon washers, including; Metric Retaining Washers made from natural Nylon, and a wide selection of Retaining Flat Washers. Also included are Sealing and Retaining, that allow premlinary mounting of a bolt before securing with a nut. The tapered design retains the screw prior to assembly - it cold forms and fully enters the pitch of the screw to provide sealing. Both the Retaining Flat Washers, and the Sealing and Retaining Washers are made from UL94 V2 rated, natural Nylon 6/6. Our plastic retaining washer offering also features a Polyethylene (PE) option, with color options including; Red, Grey and Blue.

Self Retaining Washers are ideal for applications requiring pre-assembly of the screw and washer, helping to reduce final assembly cost and save time.
