This SAE Aerospace Standard (AS) establishes the geometric control requirements for bolts, screws, and studs where worded notes and symbolized notes are used for straightness, concentricity, squareness, and runout.
This procurement specification covers bolts and screws made from a corrosion and heat resistant, age hardenable, nickel base alloy of the type identified under the Unified Numbering System as UNS N07041 and of 155 ksi tensile strength at room temperature, with maximum test temperature of parts at 1400 °F.
This SAE Aerospace Standard (AS) specifies the characteristics of screw threads - UNJ profile inch series, including a mandatory controlled radius as specified in Table 1 at the root of the external thread. The minor diameter of both external and internal threads provides a basic thread height of .5625H to accommodate the external thread maximum root radius. The following detailed design requirements are included: a Screw threads - UNJ basic profile and design profiles. b Standard series of diameter-pitch combinations for nominal thread diameters from 0.060 to 6.000 inches. c Standard thread classes and form tolerances. d Formulae for thread dimensions and tolerances. e Method of designating UNJ threads. f Tables for selected diameter-pitch combinations for close tolerance mechanical thread applications. g Tables for screw thread - UNJ profile thread limit dimensions.
This procurement specification covers rivets made from an aluminum alloy designated as 2117-T4, solution treated. The following specification designations and their rivet coatings are covered:
This procurement specification covers split cotter pins with optional ends (see Figure 1), made from a corrosion resistant steel of the type identified under the Unified Numbering System as UNS S30200.
