Solicitation Attachment 2 CLIN 0004 - DWG - SHCS .375-16UNRC-3A X 1.41 LG (DWG 7068537 PC.90).pdf

This document is a technical drawing and specification sheet for CLIN 0004 (Contract Line Item Number), detailing a machined part with assembly components. The drawing provides detailed engineering specifications including dimensional tolerances, materials, and fabrication requirements for a precision mechanical component featuring external threads, fillets, and radii specifications.

The fabrication tolerances table specifies machining and general tolerances across multiple dimensions, with allowable variations ranging from ±0.06 to ±0.26 inches depending on the dimension type and range. Critical specifications include deck thickness tolerance of ±0.2 inches, surface texture requirements per ANSI B4.36-1978, and threads to be in accordance with FED-STD-H28. Angular tolerances are set at ±1 degree for piping and ventilation ducting applications and ±5 degrees for angle between hanger mounts (60-MIN to 120-MAX) with ±5 degrees for all other applications. The document also requires that all self-locking externally threaded fasteners comply with MIL-F-18240 specifications, with self-locking inserts and specific marking requirements of a minimum of six dots (approximately 0.032 diameter) that are raised or depressed approximately 0.010 inches, preferably placed on the fastener head with side location as an alternative if necessary.
