While cone wrenches are designed to adjust the cone-shaped hubs of a bicycle wheel, the same features that make them a mainstay of bike-repair shops also make them useful in almost any workshop.
The slim jaws, which are intended to fit into the tight clearances of an axle assembly, can often be slipped into other narrow spaces where a thicker wrench would be tricky to maneuver. As an improvement on the conventional design, ours have stepped jaws that fit four common bolt sizes (13mm, 14mm, 15mm and 17mm) rather than just one. The wrenches are supplied in pairs, allowing you to hold the nut steady while turning the bolt (or vice versa).
Just 2mm thick, they are made of hardened stainless steel and have been tested to 30 foot-pounds of torque – far greater than is required for typical applications. Only 3 oz each and 7 1/4" long, the lightweight, portable tools have a soft PVC handle coating for grip.
