About this file
These engineering drawings detail three Thread Chase Tools for the U.S. Air Force, specifically for MK-84, 1.75-12 LN, and MK-84, 2.50-12 LN configurations. The drawings are technical specifications for machined steel components with precise dimensional requirements, material specifications, and manufacturing notes. Key technical specifications include:
Material: 4340 annealed round bar steel (ASTM A322), heat treated to RC-40 after machining. Each tool requires specific dimensional tolerances, thread specifications (such as 1.75-12UN-3A), and surface finish requirements. Manufacturing notes mandate removing burrs, applying a light rust-inhibiting oil coating, and ensuring high-quality workmanship with no defects. The documents are marked with Distribution Statement C, authorizing use by U.S. Government agencies and contractors, with a warning about export control restrictions. The drawings are dated February 1974 and include detailed cross-sectional views, dimensional annotations, and specific manufacturing instructions.
