The Wera 7870 Joker M self-setting insert spanner is designed for fast, accurate, and safe tightening of hexagon screw heads and bolts with sizes from 13 mm to 16 mm (or 17/32" to 5/8"). This versatile hand tool automatically adjusts its jaws to fit the fastener, providing a secure grip and minimizing the risk of slippage or surface damage. Its integrated ratchet mechanism and low 30° return angle enable efficient work, especially in confined spaces. The spanner is compatible with 9x12 mm square drive torque wrenches from the Wera Click-Torque X and XP series, allowing precise and repeatable torque application for critical assembly tasks.
