Wera 6004 Joker Self Setting Adjustable Spanner

The Wera 6004 Joker XXL is the largest variant in the range at 320mm, engineered for tackling the biggest fasteners where power and leverage are paramount. With an overall length of 322mm and a jaw range covering 24–32mm and 15/16–1 1/4" imperial, this is the go-to choice for heavy structural, industrial, and mechanical work. Despite its size, the Joker XXL retains all the intelligent features of the 6004 family. The jaws automatically and continuously self-set upon engagement with a hexagon bolt or screw, covering both metric and imperial dimensions. The lever mechanism clamps the fastener firmly to prevent slippage, while the mechanical ratchet keeps work moving at pace without needing to reposition the tool. Even at this scale, the corner-width rectangular prisms achieve a 30° return angle, and the single-arm design aids access in tighter areas than a traditional large spanner would allow.
