Attachment 1 - Drawing.pdf

This document is a detailed fabrication drawing for a mechanical component, specifically a turnbuckle or similar fastening device. The technical drawing provides precise dimensional specifications for manufacturing, including tolerance ranges for various measurements such as deck thickness and angular specifications. The drawing includes multiple views (isometric and detailed cross-sections) with exact measurements in inches, noting critical specifications like a 4.250-inch diameter, 2.125-inch length, and specific radii and angles for different sections.

The technical notes outline specific material and manufacturing requirements, including hardness testing per ASTM standards. Mechanical properties are specified, including a minimum tensile strength of 140,000 PSI, yield strength of 115,000 PSI, and an elongation of 14% in a 2-inch area. Additional manufacturing notes cover heat treatment (per MIL-H-6875), hardness testing (per ASTM E18), and threading specifications, indicating this is likely a precision aerospace or military-grade mechanical component requiring strict quality control and performance standards.
