The Wera 22 Piece Joker Combination Spanner Set is a professional-grade set of combination spanners engineered for effective use in confined and restricted installation spaces. What sets the Joker 6003 apart is its intelligent open-end geometry. The 7.5° offset open end, combined with double hexagon geometry, doubles the available placement points compared to a conventional spanner.
By rotating the wrench 180° around its longitudinal axis, four distinct placement positions are achieved, allowing bolts and screw heads to be engaged every 15°. This automatic repositioning means the spanner finds its next placement point after every turn without manual adjustment — a significant advantage when working in tight or awkward spaces. The slim ring end features a 15° crank and is robust enough for demanding applications, while a high-quality surface finish provides long-lasting corrosion protection.
The set covers a comprehensive range of sizes from 5.5mm to 32mm, making it well suited to mechanical engineers, automotive technicians, and maintenance contractors working across a wide variety of fastener sizes. Colour coding by size allows for quick tool identification on the job.
