Wera 6004 Joker Self Setting Adjustable Spanner – 6004JOKERL

The Wera 6004 Joker L is the 225mm self-setting adjustable spanner, built to handle mid-to-large fastener sizes with the same intelligent, automatic gripping action found across the entire Joker range. At 224mm in length, this model covers fastener sizes from 16–19mm, making it well suited to structural, mechanical, and heavy-duty trade applications. As with all 6004 Joker spanners, the parallel jaws self-set automatically and continuously when placed onto a hexagon bolt or screw — no manual adjustment needed. The lever mechanism engages on contact to securely clamp the fastener, minimising the risk of slippage and protecting bolt heads from damage. The built-in mechanical ratchet delivers fast, uninterrupted screwdriving, while the 30° return angle provided by the corner-width rectangular prisms ensures the spanner remains effective even in restricted working areas.
