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.
