ATTACHMENT 2 CLIN 0001 DRAWING.pdf

This is a technical drawing and fabrication specification document for a machined component assembly. The document provides detailed engineering specifications including dimensional tolerances, material requirements, and manufacturing standards for a part that appears to be an industrial casting or machined assembly with external threading and fastener applications.

The drawing specifies fabrication tolerances for casting, welding/fabrication, and machining operations with varying tolerance ranges based on dimension sizes. Key specifications include: casting tolerances ranging from ±.06 to ±.25 inches depending on dimension ranges; welding/fabrication tolerances from ±.10 to ±.26 inches; and machining tolerances from ±.02 to ±.020 inches for progressively larger dimension ranges. The document mandates that all self-locking externally threaded fasteners must incorporate self-locking inserts conforming to MIL-F-18240 specification, with minimum six dots (approximately .032 diameter) raised or depressed markings placed on the fastener head. Additional requirements include specific tolerances for fillets and radii (±.06 to ±.14), surface texture specifications per ANSI Y14.36-1978, threads in accordance with FED-STD-H28, and angular tolerances of ±1° for piping and ventilation ducting with ±.5° angles for hanger mount applications and ±.9° for all other applications.
