This specification covers the requirements for the preparation of Operating Instructions in published form or in manuscript form suitable for publication as designated herein.
The gaging practice established in this standard applies for final assessment of dimensional acceptability of the product complete thread (excluding the incomplete lead or runout thread). However, it is not the intent of this standard to preclude the use of other gaging systems or dimensional control systems provided they are properly correlated by the user and yield comparable results with respect to conformance with the requirements of ANSI B1.21M-1978, MJ metric screw threads.
This document discusses formulae considered applicable to aircraft engines having integral supercharging without aftercooling, and using gasoline introduced at the entrance to the supercharger or directly into the cylinders. Such engines are normally designated as single and two speed engines. Correction formulae for engines having two stage or exhaust turbo supercharging will not be discussed. Corrections for engines having a high degree of integral supercharging will be discussed in general terms only and no specific formulae will be presented. The correction formulae and methods listed are empirical and subject to error due to conditions beyond the scope of known corrections. Usage has indicated, however, that the correction formulae listed will provide a satisfactory approximation of power output under standard conditions.

This procurement specification covers aircraft-quality bolts and screws made from 6Al - 4V titanium alloy of the type identified under the Unified Numbering System as UNS R56400. The following specification designation and its properties are covered:
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.
