These are custom aerospace socket screws we had domestically produced for our aerospace customer at 50 pieces.  The trickiest part was the 1250 MPA requirement that our customer insisted on, which is a deviation from the standard NA0069A040046 specification.  We were able to supply the custom part faster than our original promise date at approximately 3 weeks from order receipt.  M4-0.7 thread was incorporated and test results confirmed 39-40 HRC after AMS 2759/3 Rev. F heat treat process.  NADCAP certified passivation per AMS-2700 was also performed and all certifications were provided to our customer with the parts.
