The internal offset cruciform, ribbed drives and unribbed drives, respectively are defined in IsO 14275 and ISO14276. 2 Configuration and dimensions See Figure 1 and Table 1. Dimensions and tolerances are expressed in millimetres. The presentation of run-out tolerances and surface-profile tolerances conforms to Iso 1101. 3 Designation The driver designation shall be as follows: ISO 14277-R10 Driver standard Driver code (see Table 1) 1 t ficense from IHS Not for Resale ISO14277:2002(E) A 0.08A 0.08A @G Drivers shall be made from tool steel and heat-treated to hardness 56 HRC to 62 HRC in the tip area (Jmin dimension).
