:: Quality
All Tool Joints are manufactured to meet or exceed the latest edition of API Spec 7-1 or new upcoming Spec 5 DP & Spec 7-2. The tool joint connections are precision threaded on CNC lathes and are inspected with hardened and ground gages along with precision calibrated measuring thread gages.

:: Manufacturing
Tool Joints are manufactured from 4137M Steel. The forgings are Polymer quenched and tempered to meet the required material properties. The Brinell Hardness value is checked on each tool joint for verification. Each tool joint is also Magnetic Particle Inspected (MPI) to verify there are no material defects after threading.

Tool joints are manufactured with 2” longer than standard (LTS) Tongs as a standard, but 4” LTS tongs can be supplied per customer specification.

:: Phosphate Coating
All new threads are hot phosphate coated to aid in reducing galling and adhesion of the thread compound.
