Tool joints are short sections of pipe that are attached to the tubing portion of drill pipe by means of using a flash welding process. The internally threaded tool joint is called a “box”, while the externally threaded tool joint if the “pin”
API specifications also apply to tool joints:
• Minimum Yield Strength = 120,000 psi
