AS1370 Screw Threads, Controllroot Radius (J Threads) - Metric Series

AS1370 is superseded by MA1370.

This standard establishes the basic triangular profile for the J form thread; gives a system of designating; lists the standard series threads for aerospace screws, bolts and nuts; lists the standard series of diameter-pitch combinations for diameters from 1.6 to 200 mm; and specifies limiting dimensions and tolerances.
