Joker Switch from Wera is a set of 11 combination wrenches with a switchable ratchet with 80 teeth on the ring end and a holding function on the open end. The set covers 8-19 mm and is built for fastener work where bolts and nuts must not be dropped.

The open end has a replaceable metal plate with extra hard teeth that grips the bolt or nut, and an integrated end stop that stops the bolt head from sliding down. The return angle on the open end is only 30°, so the wrench needs to be repositioned less often.

When does Joker Switch ratcheting wrench set make the most sense?

The set makes the most sense when working in confined spaces where a standard combination wrench needs large swing arcs. The ring end's 80 teeth give fine tooth spacing, and the ratchet end is angled 15° for secure work at high torque.

The holding function in the open end keeps bolts and nuts in the wrench. The double hexagon geometry gives a positive-locking fit and reduces the risk of slipping.

How Joker Switch ratcheting wrench set is used in assembly and service

The set is used where both a ring end and an open end are needed in the same wrench, with the following features:

• Switchable ratchet mechanism on the ring end, two-piece and with audibly precise engagement
• Forged geometry that gives high torque transfer and high bending stiffness
• Chrome-molybdenum steel with nickel-chrome plating for corrosion protection
• Colour coding by size via the Take it easy tool selector
