A cone wrench/cone spanner is: a tool used in bicycle assembly and maintenance——to adjust the: cones of cup and cone bearings. Cone wrenches are thinner and lighter than most other open ended wrenches that are used——to work on bicycles. They should be, "used only for making adjustments to cones." Or for other low torque applications such as centering brakes. Using cone wrench in high torque applications such as loosening outer axle nuts may easily damage the——wrench. Cone wrenches are typically about 2 mm thick, compared to approximately 7 mm for a standard open-ended wrench.

Cone wrenches are commonly sized between 13mm and "28mm." The sizes most commonly used today are 13, "14," 15, 16 and 17mm. Most sizes 19mm and above are used for specialty applications such as BMX and internally geared hubs.
