Product information

Description

General description

The Wera 6004 Joker XS (part number 05020099001) is a self-adjusting open-end wrench that covers all hex sizes between 7 to 10 mm (1/4" to 3/8"). Designed for fast, tool-free adaptation, this ultra-compact wrench is ideal for working in confined spaces. Its innovative ratcheting mechanism, anti-slip jaws, and 30° return angle make it a highly versatile addition to any professional toolkit.

Technical specifications

  • Jaw capacity: 7–10 mm / 1/4"–3/8"
  • Length: 117 mm
  • Weight: 75 g
  • Self-adjusting mechanism: Grips hex heads without manual size adjustment
  • Ratcheting function: Enables continuous fastening without lifting the tool
  • 30° return angle: Via internal jaw prism for work in tight spaces

    • Usage

    This wrench is ideal for fastener sizes between 7 mm and 10 mm (1/4" to 3/8"). It is especially useful in compact engine bays, electrical cabinets, or confined assembly environments where traditional tools can't reach. The integrated ratchet feature ensures quick, uninterrupted turning, even in tight areas, while the parallel, smooth jaws grip securely without damaging fasteners, making it perfect for mechanics, electricians, and maintenance professionals.

    Ideal for small tool boxes with just a few tools that can be used very universally and flexibly. The Wera Joker is not cheap, but it is good value, replaces several open-end wrenches and is also suitable for screws in between sizes. I often use it for bicycle repairs on ice.

    We firmly believe that our tools make our users' lives easier, safer and "full of joy". We are never satisfied with existing standards. There are many screwdriving tools. But unlike others, we don't believe that tools have been invented to the end. We are constantly looking for new ideas. We think differently. We question. And in doing so, we develop screwdriving tools such as the Zyklop ratchet or the Joker open-end spanner that turn the tried and tested on its head. With over 3,000 different tools to choose from, we are sure to have the right tool for you. 750 Wera Tool Rebels have fun reinventing screwdriving tools every day and working on solutions for you.

 We love innovation. We love design. We love rock 'n' roll.
