AS7245B

This specification covers closely-wound helical coil, screw thread inserts made of a corrosion resistant steel formed wire with a chemical composition in accordance with Table 1 and identified under the Unified Numbering System as UNS S30200 or UNS S30400 that can be formed by an insert manufacturer to achieve the requirements of this procurement specification. The inner surface of the insert coil, after assembly into a screw thread tapped hole, provides internal threads of standard 60° Unified form.

AS3062D

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.
