Wera Joker Double Open-Ended Wrench

The Joker’s clever double-hex geometry delivers a very positive connection with nuts or bolts – it’s a perfect fit. And the exchangeable, hardened metal gripping plate in the Joker’s mouth literally bites itself into the bolt, with its extremely hard tips. Both features combine to prevent slipping, even at higher torque.

Instead of 60°, the Joker only has a 30° return angle thanks to it’s unique double-hex design. Along with the Joker’s straight neck, this means that flipping the wrench has become a thing of the past. With the Joker, you can now loosen and tighten nuts and bolts, in situations where conventional tools fail. Particularly in confined spaces, where conventional open-jawed wrenches cannot be used. The combination of limit stop and small return angle enables eff ective work, even on screw pipe connections.
