Self‑setting Joker S insert spanner fits 10‑13 mm fasteners, 9×12 mm drive, 30° return angle – perfect for torque wrenches and tight spaces.
The Wera Joker S Self‑Setting Insert Spanner is designed for rapid, reliable work with torque wrenches and ratchets. Its specialised head features Joker parallel‑jaw technology that automatically grips any fastener between 10 mm and 13 mm, eliminating the need to change individual spanners. The 9×12 mm square drive makes it compatible with standard torque tools, while the 30° return angle allows operation in tight or confined spaces without the tool striking surrounding material.
By replacing several individual spanners with one versatile head, the Joker S saves time on the bench and reduces the number of tools you need to carry. Its robust construction ensures durability even in demanding workshop environments, making it an essential addition to any professional mechanic’s kit.
