Proxxon Socket spanner set

The socket sizes range from 8 to 34 mm (the latter for M 22 according to the new ISO standard). Deep sockets are available in sizes 13, 17, and 19 mm for long protruding threaded bolts. Special spark plug sockets are offered in 16 and 21 mm. For further details, please see the illustration.

The most important part is the ratchet mechanism, which is forged from a single piece of CrV steel. It is hardened and features flawless gearing, with multiple teeth (52 in total) engaging simultaneously to transmit extremely high torque. It includes a trigger for easy removal of the sockets at the push of a button.

The set comes in a robust, powder-coated steel box that features a torsion-resistant, unbreakable molded insert made of injection-molded polypropylene. It is oil-resistant, acid-resistant, and easy to clean, with permanently legible markings for all socket sizes.
