Lock washer Sturmey-Archer 13/32" 2x9.5mm (HMW526)

The washer fits into the frame and helps secure the wheel so it remains in place even if the axle nuts become loose. The washer is not round; its shape is keyed to match the axle. It is marked “SA” and “TOP”. The “TOP” mark indicates the washer’s orientation: its top must face upwards.
