Wera 4 Piece Joker 6004 VDE Insulated Self Setting Spanner Set

The Wera 6004 Joker 4 Piece VDE Insulated Self Setting Spanner Set is a professional electrician's spanner set, individually tested to IEC 60900 at 10,000 V for safe working at voltages up to 1,000 V.

Each spanner in this set automatically and continuously self-adjusts to grip hexagonal fasteners across a range of metric and imperial sizes, eliminating the need to manually set jaw width. The integrated lever mechanism clamps securely onto the bolt or screw head, significantly reducing the risk of slippage or fastener damage — a critical advantage when working on live or sensitive electrical installations.

The built-in ratchet function allows fast, consistent tightening and loosening without removing the tool from the fastener, making these spanners particularly well suited to confined spaces. A return angle of just 30° is achievable using the corner-width rectangular prisms, while the single-arm design further aids access in restricted areas. The 2-component insulated handle provides a naturally comfortable grip, with anti-slip protection at the front end for added security.

The sliding function enables contactless, safe opening of the non-insulated jaws, providing an additional layer of protection for electricians and contractors working on electrical systems. All four spanners are supplied in a compact textile storage box with a hook and loop fastener strip included.
