A retaining or push-on washer grips a plain shaft to hold a part in place without a groove or thread, giving a quick, low-cost way to lock things axially. Shaft diameter and material are the main choices.
CSG keeps parts like this on hand as part of a managed C-parts program, so you can order them alongside the rest of your fasteners instead of chasing separate suppliers. Ask us for a quote or see what else we stock.
