Wera 6004 Joker Self Setting Adjustable Spanner

The Wera 6004 Joker M is the 190mm mid-size self-setting adjustable spanner, striking an excellent balance between versatility and reach for a broad range of trade and workshop applications. At 188mm in overall length, this model covers fastener sizes from 13–16mm and 1/2–5/8" imperial — bridging the gap between the smaller S and larger L variants. The Joker M features the same self-setting jaw technology found across the range, automatically and continuously adjusting to the correct fastener size upon contact with no manual intervention required. The integrated lever mechanism securely grips the fastener to prevent rounding or slippage, and the mechanical ratchet allows rapid, consistent driving without removing the tool. With a 30° return angle delivered by the corner-width rectangular prisms and a single-arm profile, the Joker M performs reliably even in confined or restricted working conditions. Features and Benefits: • Self-setting jaws automatically grip metric and imperial hexagon fasteners • Lever mechanism prevents slippage and protects bolt heads • Mechanical ratchet for fast, uninterrupted screwdriving • 30° return angle suitable for tight and restricted spaces • Mid-size M format ideal for a broad range of general trade tasks Contents: 6004 Joker M Self-setting spanner, 13–16mm x 1/2–5/8" x 188mm Specifications: • Configuration: 190mm
