Joker ring spanner

The Joker ring spanners by Wera represent the new generation of ring spanners. They have a return angle of 30° instead of 60° as in conventional ring spanners. This is advantageous in confined assembly spaces where a conventional ring spanner has to be continually turned over. The special holding function of the Joker ring spanner by Wera allows nuts and bolts to be directly and reliably applied where they are needed. Conventional ring spanners have to be continually reapplied and the force used has to be carefully controlled to avoid any risk of injury. The Joker ring spanner prevents any slipping downwards from the bolt head thanks to its limit stop. The double-hex geometry of the Joker ring spanner makes for a positive connection with nuts or bolts – a perfect fit. And the exchangeable, hardened metal plate in the Joker’s mouth literally bites itself into the bolt with its extremely hard tips. Both aspects prevent any unpleasant slipping, even at higher torque. The Joker Switch features a ratchet end that is angled at 15° to the tool axis, making application of the tool in confined spaces much easier. The switch lever guarantees a convenient change of direction.

The Joker ring spanner by Wera is just the right tool, also for your requirements!
