We had 5,000 pcs of these custom 4037 alloy steel flat socket head screws produced in the USA for our aerospace customer. ASTM A574 4037 material was used for the production and the cadmium plating was dome per AMS-QQ-P-416A TYpe II, with thickness at 0.0005-.0008". Heat treat was performed to get the hardness of the parts to Rc 41-45. The socket drive was cold formed and the thread rolled, both at the same facility. Full certs were provided with the parts per our customer's requirements.

We supplied approximately 450 pieces of these custom domestic L anchor bolts to our construction engineering customer, with full certs. The parts had to be domestic made using domestic melt material as well in ASTM A675 Grade 80 steel, with plain finish. 1/2-13 thread was incorporated on the 15" long leg, with 13.5" of actual thread - having to cut this length of thread on each piece made the production process significantly slower. The short leg measured 2".
