Wera Joker Spanners are made of a forged, full metal body (chrome-molybdenum). This gives the Wera Joker Spanners a build quality you can immediately feel when you pick up a spanner.
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 Wera Joker spanners prevents slipping off of the fastener head with its integrated limit-stop – no longer is the thumb needed to act as a depth stop. This makes applications much easier and allows significantly more force to be applied during fastening jobs.
The Wera Joker spanners have a holding function that means that nuts and bolts can be held in the jaw and easily positioned where they are needed. Fastening on to the thread can then be done quickly and safely, thanks to the innovative special stop-plate which holds the fastener. No more time-wasting searches for dropped nuts and bolts! After applying and positioning the nut or bolt, fastening can begin immediately – no additional tools required.
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.
30º Return Angle
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 effective work, even on screw pipe connections.
