    Product Description
    Crab bolts are unique forgings that KDK produces for the rail engine industry. The   sizes of the crab bolts required are fairly standard. Crab bolts are a critical   component of large locomotive engines. They are typically made from 4140 material.   KDK has the dies for these forgings and is able make the Crab bolt according to   your specifications. Crab Bolts can be heat treated or sand blasted according to   your specifications. This can bring the forgings to the hardness level. Hardness   levels are tested or certified within the desired range. The forging process adds strength to the steel bar. This improved grain flow which is achieved as a result of the forging process provides strength that can be viewed from a microscope. One of the common problems that has come from the use of forgings for gears has been the appearance of flash lines or parting lines. KDK produces Crab bolts with very minimal flashing on the forging making the machining of the bolts easier. Crab bolts can be shipped using returnable containers or corrugated boxes. Depending on your requirements, KDK will make a custom die for your forging need. Please send us a copy of your drawing and we will be happy to send a quote to you.
