Scope: This standard is for serration shafts (serrations) with constant space angle of 60?at external toothing, 28 to 42 teeth and pitch diameters from 7 mm up to 60 mm. Serrations as in this standard are used for connecting hubs to shafts either with a permanent or a removable connection, but which, due to the expected wear, is never a sliding fit connection. As the teeth are relatively small, only small torques can be transmitted by such connections. The following principles apply to serrations as in this standard: a) Shafts have a uniform space angle. b) Shafts may have curved flanks generated by machining with straight-flanked hobs (see Figure 1). c) Where hubs may have curved tooth flanks (to allow for machining by means of involute hobs), this is to be separately agreed upon by the manufacturer and the customer. d) The "rough" deviations for shafts apply in cases where the force only acts in one direction (torsion bar spring). e) Side fit.
