A pin cap lock washer sits beneath or around the cap of a pivot pin, using its locking geometry to prevent the cap from backing out or rotating loose during repeated use. On a hydraulic thumb attachment, the pivot pins are under constant stress as the thumb grips, curls, and releases material — a failed or missing lock washer can allow the pin cap to work free, leading to pin migration and accelerated wear in the thumb's pivot bore. Replacing a worn or damaged washer promptly keeps the pin assembly secure and the thumb operating with consistent, predictable force.
