Wera Joker Double Open-Ended Wrench - 17 + 19mm

If you need a wrench, use the Joker!
The Joker performs fastening jobs in almost every conceivable situation, quickly and with great precision. The specially forged geometry, in combination with high-performance chrome-molybdenum steel and nickel-chrome coating, means that you win three times over: longer service life, high resistance to wear and great protection against corrosion

Fastener Holding Function
The Joker's holding function means that nuts and bolts can be held in the jaw and easily positioned where they are needed. Fastening onto the thread can then be done quickly and safely, thanks to the innovative special stop-plate which holds the fastener.

Secure Grip on Fasteners
Constant re-positioning of the wrench? Difficulty holding fasteners in confined spaces? Easing off to avoid any risks of injury or fastener damage? That was yesterday. Today, the Joker prevents slipping off of the fastener head with its integrated limit-stop - no longer is the thumb needed to act as a depth stop.

Safer due to anti-slip effect.
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 any unpleasant slipping, even at higher torque.

Very small return angle
Less can be more. Particularly in those very confined spaces where conventional wrenches with a 60 degree return angle literally have to be turned over and over, to tighten and loosen nuts or bolts. Instead of 60 degrees, the Joker only has a 30 degree return angle thanks to its unique double-hex design.

    Please make the 12x14 to complete the most common sizes from 10-19.

    Wish they offered a complete set of these.

    I already have plenty of ratcheting wrenches, but wanted to try the Joker open end. They seem to be a slightly tighter fit than my blues point and use made Craftsman, but not so tight that they're annoying to use. I wish they would make a full set, or at least make a 12/14mm size for working on Japanese bikes and cars. We don't all work on Volkswagens, Wera!

    What makes a Joker wrench special?

    Posted by William Lee on Jun 26th 2015

    First there is the fact that it is a precision tool. The wrenches fit the sizes they are made for closely. For me that means no skinned knuckles. When the wrench is on a bolt or nut it stays there until it is removed. In addition the wrench will help with one of the most frustrating situations one can face, not enough hands. Its ability to hold a nut in place while the bolt is started into the threads is fantastic!
