HACKER LARGE DIAMETER TOOL JOINTS (Casing Connectors) provide quick make up and good stabbing characteristics, thus eliminating many of the difficulties usually encountered with standard threaded ends. Our coarse thread eliminates cross threading, and the design of the ample shoulder provides a strong bearing-drive area.

Standard specifications include right-hand Buttress Threads of Modified Internal Flush Threads. Left-hand or other types of threads are available on special order.

With this weld-on type of heavy duty tool joint, you have a joint stronger than the casing itself. Standard materials include 1018, 1020, 1029, 1030 steel or 4130/4140 alloy.

Hacker Large Diameter Tool Joints are available in sizes to fit pipe from 103/4" OD through 30" OD. Prices available on request.

NOTE: WHEN ORDERING, be sure to give type of thread and type of steel, as well as OD size and the wall thickness of the pipe or casing to which the Hacker Large Diameter Tool Joint will be welded.
