Wera have incorporated a hardened metal gripping stop plate on the head of the Joker which serves a number of purposes. Firstly it carries out a holding function to ensure that nuts and bolts are held in the jaw and can be easily positioned where they are needed, bringing an end to dropped nuts or bolts. The fastening of the nut or bolt can then be carried out quickly and safely thanks to the stop-plate that holds the fastener in place.
The stop plate also acts as an integrated limit-stop to prevent the Joker slipping off the fastener head. No longer is the thumb needed to act as a depth stop when fastening, preventing risks of personal injury and damage to the fastener head. This limit-stop not only makes things much easier, especially when working in confined spaces, but also allows much more force to be applied to the fastener. The Joker is made from high performance chrome molybdenum steel, which combined with a nickel-chrome coating will ensure a longer service life, high wear resistance and protection against corrosion. A special double-hex geometry delivers a very positive connection between the Joker and nuts or bolts.
The gripping plate within the head bites into the bolt with its extremely hard tips. These features act in combination to prevent unpleasant slipping even at higher torque. The ratcheting function at the ring end has a fine tooth mechanism with 80 teeth to provide greater flexibility.Conventional wrenches have a return angle of 60 degrees, meaning that they have to be turned over again and again to tighten and loosen nuts or bolts. By comparison, thanks to the double-hex geometry the Joker has a return angle of just 30 degrees. Along with its straight neck, this means that nuts and bolts can be tightened and loosened in situations where conventional wrenches cannot cope. Particularly useful when working in confined spaces.
