This washer is important to the restorer as it is slightly thicker and features a small outside diameter, allowing fitment under the nut or bolt head where reduced diameter is required. Suitable for authentic restoration work and offers broad compatibility with many Triumph, BSA, and Norton models. The plain washer measures 5/16″ ID, 5/8″ OD and is 1/16″ thick. A zinc finish protects the washer from corrosion and rust. Made in the UK to exacting standards. Used in applications where a robust washer is required for friction reduction and where a slightly smaller spotface exists, such as on stators and carburetor mounting flanges. The washer is placed under the head of the nut or bolt to minimize friction and spotface damage when the fastener is tightened.
