Axle nuts for Sturmey-Archer three-speed hub gears.

• HMN129 (right) is the guide nut with an opening for the indicator chain and a window at the side. The chain runs through the nut to the gear cable.
• HMN128 (left) is the hex nut for the left-hand side of the axle.
• HMN388 (left, dome) is a dome nut for the left-hand side of the axle. It can be used instead of HMN128 and covers the axle end.

Compatible hubs:

• AW, S-RF3
• AWC(II), S-RC3(II)
• TS-RF3, TS-RC3, QS-RC3
• SX-RB3, SX-RK3

and other Sturmey-Archer hubs with a 13/32″ (about 10.3 mm) × 26 TPI axle thread.

Tighten the nut firmly but do not overtighten it: the fine thread strips easily.

Not compatible with Torpedo/SRAM/Sachs hubs! These have an FG 10.5 mm axle; use the left-hand Torpedo/SRAM axle nut and the right-hand Torpedo/SRAM axle nut instead.
