* TOOL JOINT PLUS DRILL PIPE.

** THE TENSILE STRENGTH OF THE TOOL JOINT PIN IS BASED ON 120,000 PSI YIELD AND THE CROSS SECTIONAL AREA AT THE ROOT OF THETHREAD 5/8 INCH FROM THE SHOULDER.

*** TORSIONAL YIELD STRENGTH BASED ON SHEAR STRENGTH OF 57.7% OF THE MINIMUM YIELD STRENGTH.

1 RECOMMENDED MAKE-UP TORQUE IS HALF OF TOOL JOINT TORSIONAL YIELD.
