6004 Joker S self-setting spanner, 10-13 mm and 7/16"-1/2", 154 mm - Wera 05020100001

Instead of several single spanners, the Joker S covers wrench sizes 10 to 13 mm and 7/16" to 1/2" with one tool. Its continuously adjustable parallel jaws find the required size automatically when placed on the bolt or nut, no setting required.

Benefits

• Self-setting: automatic, continuous gripping of hexagon screws and nuts across the whole size range.
• The lever mechanism clamps the screw or nut securely between the jaws and reduces slipping and damage.
• Smooth parallel jaws apply surface pressure and prevent rounding of the nut or screw head.
• Ratchet function in the jaw for fast, consistent screwdriving without removing the spanner.
• Corner-width prisms in the jaw allow a return angle of only 30°, the single-arm design helps in confined spaces.
• Hanging hole for tidy storage on the workshop wall.

Applications

For assembly, maintenance and service on machines, vehicles, bicycles and installations with metric and imperial hex fasteners, wherever one spanner should replace several sizes.
