Wera 7870 Joker M Self-Setting Insert Spanner Head, 9x12mm Drive, 13–16mm
Wera 7870 Joker M Spanner Head (13–16mm) with self-setting jaws & 30° return angle. Ideal for tight spaces.
The Wera 7870 Joker M Self-Setting Insert Spanner Head is designed to revolutionise your work with fasteners. Featuring Wera's unique Joker parallel jaw technology, this insert head automatically adjusts to grip any fastener within its 13–16 mm range. This self-setting function eliminates manual adjustments, saving time and effort.
Engineered for compatibility with standard torque wrenches and ratchets featuring a 9×12 mm square drive, this spanner head transforms your tools into versatile, multi-size solutions. Its compact design includes a 30° return angle, making it ideal for tight, confined spaces where full spanner swings are impractical, improving accessibility and reducing fatigue.
Covering four common metric sizes (13, 14, 15, and 16 mm) in one head, the Wera Joker M replaces multiple individual spanners, minimising tool clutter in your workspace. Built to Wera’s high-quality standards, it ensures durability and precision. The secure self-gripping jaws reduce slipping risks, making it ideal for mechanical repairs, assembly, and maintenance tasks.
