Custom custom Inconel 718 double thread offset studs were manufactured for our aerospace customer. The offset head, double thread, and hardness of material made these parts extremely difficult to manufacture. The head radius measured .203″ and a combination of 5/16-24 2A and 1/4-28 2A thread was cut to a length of .842″. Definitely one of the toughest parts we have dealt with – the hardness of the material created countless issues with tool life. Full certs with FAIR were provided with the parts.
