This standard establishes the rolled thread element tolerances for lead, half-angle, taper, and out-of-roundness for studs used in aerospace construction; it also establishes the requirements for lead threads and runout threads for these studs.

This standard defines the requirements for runout threads and lead threads for bolt and screw rolled threads used in aerospace construction; it also specifies a referee method, by optical projection, for establishing conformity with these requirements which agree with ISO 3353.

The bolt and screw lead and runout thread requirements are also applicable to other externally threaded products where the threads are produced by rolling.
