Wera 6004 13-16mm Joker M VDE Insulated Self-Adjusting Spanner

The Wera 6004 Joker M VDE Insulated Self-Adjusting Spanner represents a leap forward in combination spanner design, merging intelligent mechanics with certified electrical safety. This tool automatically and continuously grips all metric and imperial hexagonal sizes within its 13mm to 16mm range, eliminating the need for manual adjustment and speeding up workflow. Its ingenious integrated lever mechanism securely clamps screws and bolts between the jaws, dramatically reducing the risk of dangerous slippage and damage to fastener heads.

Engineered for electricians and technicians, each tool is individually tested to IEC 60900 standards at 10,000 V, certifying it for safe live working up to 1,000 volts. This safety is enhanced by the two-component plastic insulated handle, which provides a comfortable, secure grip. Additional protection is offered by anti-slip protection at the handle's front end and a unique sliding function that allows for the contactless, safe opening of the non-insulated jaws.

The spanner's clever design excels in confined spaces. A mechanical ratchet function enables fast, consistent screwdriving without removing the tool from the fastener. When used in conjunction with the corner-width rectangular prisms in the jaw, a remarkably small back-pivoting angle of only 30° is possible. This single-arm design, combined with the ratchet and compact pivot, makes tackling tight, awkward fittings far more efficient.
