SAE/ANSI B 92.2M:1980 (R1989)

This standard provides data and guidance for the design, manufacture, and inspection of straight, non-helical, cylindrical involute splines. It establishes a specification based on the metric module within the range 0.25-10 inclusive, relating to nominal pressure angles of 30 deg, 37.5 deg, and 45 deg. For computer programming, the term '37.5 deg' has been adopted instead of '37 deg, 30 min'.
