Wera 6004 Joker Self Setting Adjustable Spanner

The Wera 6004 Joker XL is the 250mm self-setting adjustable spanner, designed for larger fastener sizes where extra length provides the leverage and control needed for demanding tasks. At 256mm overall and covering fastener sizes from 19–24mm and 3/4–15/16" imperial, this model sits between the L and XXL variants and is well suited to mechanical, engineering, and heavy trade applications. The self-setting jaw mechanism engages automatically and continuously when the spanner is placed onto a hexagon bolt or screw, setting the correct jaw width without any manual adjustment. The lever mechanism then clamps the fastener securely, reducing the risk of slippage and preventing damage to bolt heads. The mechanical ratchet function maintains working pace without the need to lift and reposition the tool, while the 30° return angle from the corner-width rectangular prisms and the single-arm design keep this large spanner usable even in tight working areas.
