SAE 4-spline shaft section, nominal 3/4 in, fit A (permanent)

SAE 4-spline shaft section, nominal 3/4 in, fit A (permanent): major Ø19.050 mm (0.750 in), spline width W4.597 mm (0.181 in), root Ø16.180 mm (0.637 in), 4 parallel-sided splines; maximum values of the tables; the 19.0 mm length (equal to the major diameter) is an example, no chamfer, no bore

Exact dimensions. True size, no tolerance added. Threads are plain cylinders at the major diameter.
