Sealing & Retaining Ring Washer Sealing & Retaining Ring Washer

These nylon washers are designed to prevent the loss of screws and bolts and to protect surfaces. The washer allows preliminary mounting of the bolt before securing with a nut. The tapered part of the washer provides locking and the screwed assembly. The tapered part of the washer cold forms and fully enters the pitch of the screw to provide sealing. The tapered part is a smaller diameter that the screw and is used to retain the screw before assembly. Compare to "Dubo" washers.
