The Wera 6003 Joker Ring Spanner has two sets of hexagonal teeth meaning it can engage with a nut with only a small movement of the handle making it great for getting into tight spaces.

The special mouth shape is made by taking a standard hexagonal spanner and rotating the teeth 7.5° and overlaying them with the original set, the two sets of teeth can now engage with a standard hex nut twice as often (or with half with movement of the handle), the slightly offset mouth opening means you can also flip the spanner over to further decrease the amount of movement needed to reach into tight places. The ring end of the wrench is angled upwards 15° from the handle to allow you to reach over small obstructions (with the ring end flat over a nut the handle will be angled upwards over the obstruction). We stock the Wera Joker Spanner in a number of sizes suitable for guitar, for example the 10 mm size is the standard for modern hex nut tuners and the 1/2" size is used on imperial CTS potentiometers. The spanners are colour coded so you can quickly find the size you need and they have a high quality surface treatment for long lasting corrosion protection.
