Adjustable spanner Wera 6004 Joker XS

The Wera 6004 Joker XS Adjustable spanner is a compact, self-setting wrench designed for gripping and turning hexagon bolts and screws. With continuous parallel jaws and an integrated lever mechanism, the spanner automatically adapts to metric and imperial sizes up to a maximum jaw width of 1 cm, enabling firm clamping and reduced risk of slippage or damage. The ratchet function allows for fast screwdriving without removing the tool, and the single-arm design with corner-width rectangular prisms provides a small return angle for work in confined spaces.

Advantages

The design combines an automatic, continuous jaw adjustment with an integrated lever that securely clamps fasteners, reducing the need to change individual spanner sizes. Its ratchet feature permits rapid, uninterrupted turning and the compact 1 cm jaw width and single-arm layout improve access in tight areas. The tool’s metallic finish and precision construction offer durable, precise handling for a range of applications.

Suitable for

• Tight-space fastening and loosening of hexagon bolts and screws
• Jobs requiring rapid, repetitive turning where a ratchet action is beneficial
• Situations needing a small, universal tool that replaces several spanner sizes

How to use

Place the Joker 6004 jaws around the hexagon head of the bolt or screw and allow the continuous jaws to self-adjust to the required size. Engage the integrated lever mechanism to clamp the fastener securely between the jaws. Use the ratchet action to turn the fastener without removing the tool; when working in confined spaces use the corner-width rectangular prisms to obtain a reduced return angle of approximately 30°.

Usage recommendations

Use the spanner within its maximum jaw width (1 cm) and avoid forcing it on fasteners that exceed this size. Inspect the jaws for wear before use and maintain a clean contact surface to minimise slippage. For optimal longevity, store the tool dry and apply light lubrication to the ratchet mechanism if required.
