HUB AXLE WASHER REAR SERRATED WALD 318

The Wald 318 Rear Serrated Hub Axle Washer is a classic, highly durable bicycle hardware component designed for 3/8-inch axles. Made in the USA, these serrated steel washers are considered the "correct" vintage choice for older cruisers, BMX, and classic track bikes to bite firmly into the dropouts and prevent the rear wheel from slipping or spinning under chain tension.
