About this file
This is a contract attachment specifying the requirements for manufacturing self-locking cap screws. Item 0003 requires the production of cap screws with stock number 5305-LL-DM1-1975, sized 0.500"-13UNC-3A x 2.00" long, fabricated from nickel-copper-aluminum (K-Monel) material per specification QQ-N-286G in Type IV configuration (hexagon socket, flat countersunk head at 82-degree angle) per federal specification FF-S-86E and military standard drawing MS18116.
The screws must incorporate a self-locking element per MIL-DTL-18240F(1) classified as Type "L" or "P" and include a minimum of six dots approximately 0.032 inches in diameter, raised or depressed 0.010 inches, marked on the fastener head. Material must be hot-finished or cold-drawn, annealed, and age-hardened; Form 1 material requires solution annealing after heading and threading, while Form 2 material requires threads to be cut or ground only. One heat is required for quantities of 50 units or fewer. Protective coating and cross-drilling are not required. The contract mandates material certification and certificate of compliance documentation (for cap screws 1/2" diameter and larger), compliance with controlled industrial material marking and certification requirements, mercury control restrictions, and K-Monel material restrictions. Preservation, packaging, and inspection requirements are addressed through referenced FAR clauses D4, D5, E1, E2, and E504.
