Wera Joker 6004 16mm-19mm VDE Insulated Self-Setting Spanner

The Wera Joker 6004 VDE Insulated Self-Setting Spanner is a revolutionary tool designed for electricians and professionals working on live electrical systems up to 1000V. Each spanner is individually tested to 10,000 V in accordance with IEC 60900 standards, providing certified safety and peace of mind when working in hazardous environments. Its unique self-setting mechanism automatically and continuously grips all hexagonal nut and bolt sizes within its 16mm to 19mm range, accommodating both metric and imperial fasteners with unparalleled ease.

A key innovation is the integrated lever mechanism. As torque is applied, the jaws securely clamp down on the fastener, significantly reducing the risk of slippage and damage to the workpiece or the tool itself. This is complemented by a mechanical ratchet function, allowing for fast and consistent screwdriving without the need to remove and reposition the spanner after each turn, dramatically speeding up repetitive tasks.

Ergonomics and Safety Features

Engineered for comfort and control, the spanner features a two-component plastic insulated handle. This design ensures a naturally comfortable and secure grip, even during prolonged use. Additional safety is provided by anti-slip protection at the front end of the handle and a clever sliding function. This sliding mechanism allows for the contactless and safe opening of the non-insulated jaws, offering an extra layer of protection for the user.

Designed for Confined Spaces

The single-arm design, combined with the ratchet function and the placement of the jaws on corner-width rectangular prisms, enables a remarkably small return angle of only 30°. This makes the Joker 6004 exceptionally effective in tight, confined spaces where a traditional spanner cannot achieve a full swing, such as in electrical cabinets, control panels, or machinery.
