Description This 12-piece set of reversible ratchet combination spanners is designed for professional and DIY use. Made from hardened and tempered chrome vanadium steel, they offer durability and corrosion resistance. The spanners feature a 100-tooth ratchet mechanism that allows for a 3.6° swing angle, enabling efficient work in tight spaces. The open ends are set at a 15° angle, ideal for limited access areas. The ring ends are 12-point, providing a secure grip on fasteners by engaging the flats rather than the corners, which helps prevent damage and distributes torque evenly. The reversible design allows for easy change of torque direction without removing the spanner from the fastener. The set is supplied with a practical storage rack for organization and portability. Specifications Set includes 12 spanners with sizes: 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm, 19mm Lengths vary from approximately 134mm to 246mm Compatibility and Accessories Compatible with
