The Wera Joker 6004 is an adjustable ratcheting wrench that sets itself to the fastener. Its parallel jaws grip hex bolts and nuts continuously across a range of metric and imperial sizes, so one tool stands in for several fixed spanners. A lever mechanism clamps the hexagon between the jaws to reduce slipping and rounding, and the mechanical ratchet lets you turn without lifting the tool off. The corner-width prisms in the mouth give a 30-degree return angle, and the single-arm head reaches into tight spots. It suits mechanics, bike and appliance repairers, and anyone who wants one wrench instead of a roll of spanners; the trade-off is a bulkier, heavier head than a plain fixed combination wrench.

Owners rate the Joker 6004 for its self-setting grip and ratchet, calling it a handy one-tool substitute for a set of spanners. Criticism centers on the bulky head and on grip limits with rounded or very tight fasteners.
The Wera Joker 6004 is a self-setting wrench with continuous, parallel jaws. It replaces several single spanner sizes. The size sets itself automatically when the tool is placed on a hexagon bolt or screw.
An integrated lever mechanism clamps the hexagon screw or bolt between the jaws. This reduces the risk of slipping or damage. A ratchet feature allows fast, consistent screw driving without removing the tool.
Placing the wrench in the corner-width rectangular prisms in the jaw gives a return angle of only 30°. The single-arm design, ratchet feature and corner-width prism make it possible to work in confined spaces. It covers all metric and imperial dimensions in its field of application.
