Tool Joint Clamp

Tool Joint Clamps are utilized to help secure the cushion sub or saver sub to the rotary spindle below the top drive. In the event the threads were not made up to the proper torque specifications the primary purpose of the clamp is to prevent the threaded connections from breaking loose during the drilling operation. The clamp will eliminate the use of thread lock and or welded tabs to secure the components to the spindle.

The Tool Joint Clamp consists of two flanges manufactured from high strength alloy steel and a diamond shape serrated tooth insert also machined from alloy steel and heat treated to provide maximum strength. These parts are utilized to form an integral assembly using high strength 12 pt. cap screws. The flanges are machined with a tapered bore and oppose each other to centralize a split serrated insert machined to suit the bore flanges. As the cap screws are tightened, the taper configuration will wedge the insert tighter around the outside circumference of the two parts you wish to secure.

The gripping pressure of the clamp is always uniform around the shaft for full engagement to prevent the threaded tool joints from backing off. Tested to withstand rotational torque exceeding 45,000 lbs.
