Wera 6004 Joker M Self-Setting Adjustable Spanner 13-16mm

Summary

The Wera 6004 Joker M is a self-setting adjustable spanner covering all metric and imperial hexagon sizes in the 13-16 mm (1/2-5/8 in.) range. Designed for professional tradespeople, it eliminates the need to carry multiple fixed spanners by automatically gripping the correct size on contact. Its integrated ratchet function and compact single-arm head allow fast, efficient torque application even in restricted access areas.

Features

• Automatically and continuously grips hexagon screws and bolts - no manual size adjustment required.
• Parallel smooth jaws distribute surface pressure evenly, significantly reducing the risk of rounding bolt or screw heads.
• Integrated lever mechanism securely clamps the fastener between the jaws when torque is applied, preventing slippage and damage.
• Mechanical ratchet function enables fast, consistent screwdriving without the need to remove and reposition the spanner.
• Return angle of only 30deg achieved via corner-width rectangular prisms in the jaw, ideal for tight spaces.
• Single-arm design keeps the head compact, making the tool highly practical in confined working areas.
• Covers metric sizes 13, 14, 15, and 16 mm, and imperial equivalents 1/2", 17/32", 9/16", 19/32", and 5/8".
• Replaces several individual fixed spanners in a single versatile tool.
