The Proxxon special socket set for multi-point screws XZN comes in a sturdy, powder-coated steel case. It is suitable for engines (cylinder heads), drive shafts, and rear axles. The set features a 1/2" square drive (12.5 mm) and includes socket inserts ranging from 5 to 14 mm in standard length (55 mm) as well as from 6 to 14 mm in extra-long length (100 mm). Additionally, it contains 12-point inserts from 9 to 21 mm. A table for thread sizes from M 1.6 to M 24 with tightening torque values is permanently fixed to the lid. The hardness and maximum torque values exceed the requirements of DIN/ISO standards. The dimensional accuracy is within the permitted tolerances. The set includes torsion-resistant, indestructible molded inserts made of injected polypropylene, which are oil- and acid-resistant and easy to clean. All sizes are permanently marked for easy readability. The set is also excellent for storage in the drawers of standard workshop carts. XZN (18-piece).
