6004 Joker M self-setting spanner, 13-16 mm and 1/2-5/8", 188 mm - Wera 050201030011

Instead of several spanners, a single tool grips metric and imperial hexagons. The Joker M sets itself continuously to wrench sizes from 13 to 16 mm and 1/2" to 5/8" when placed on the fastener and ratchets on without removal.

Benefits

• Automatic, continuous gripping: the required size sets itself when the tool is placed on the bolt or screw.
• Lever mechanism clamps the hexagon between the jaws and reduces slipping and damage.
• Parallel smooth jaws with surface pressure prevent rounding of nuts and screw heads.
• Mechanical ratchet function for fast, consistent screwdriving without removing the spanner.
• Return angle of only 30° using the corner-width prisms in the jaw, single-arm design for tight spaces.

Applications

Assembly, maintenance and service on external hex bolts and nuts in workshops, mechanical engineering, building services and vehicle technology, especially where metric and imperial fasteners meet.
