Tooth proportions for fine-pitch gearing are similar to those of coarse pitch gearing, except in the matter of clearance. For 20 degree profile angle fine-pitch gearing, this standard provides a system of enlarged pinions which use the involute form above 5 degrees of roll. Data for 14-1/2 and 25 degree profile angle systems are included in annexes. Metric version of AGMA 1003-HXX.
