Sockets can be packaged in customer containers or can be shipped in disposable packaging. Heat treating services as well as normalizing for ease of machining, quench and tempering for added hardness are also offered. We use the upset forging process which adds strength to the steel verses machining from solid stock and uses less material than machining from a solid bar. Improved grain flow which is achieved as a result of this process, provides additional strenght. Depending on your requirements, KDK will make a custom die for your forging needs.
