The Wera 6004 Joker 4-Piece Self-Setting Adjustable Spanner Set is a versatile adjustable spanner set designed to replace multiple individual spanners across both metric and imperial applications, covering sizes from 7 to 19 mm and ¼" to ¾". Each Joker spanner in the set automatically and continuously adjusts to the fastener as it is placed onto a hexagonal bolt or screw head. An integrated lever mechanism then clamps the jaws securely around the fastener, significantly reducing the risk of slippage and protecting both the fixings and the surrounding material. The built-in mechanical ratchet allows fast, consistent tightening and loosening without removing the tool from the fastener. Corner-width rectangular prisms within the open end deliver a return angle of just 30°, and the single-arm design makes these spanners well suited to confined and restricted-access areas. The set is supplied in a compact folding pouch capable of covering at least 18 different metric and imperial screw drives. The pouch features a hook-and-loop fastener on the reverse, making it compatible with walls, shelves, workshop trolleys, and the Wera 2go system for organised tool storage.
