Threaded subs are essential components used to connect different drilling tools or adapt thread types within the drill string. At the vendor’s facility, these subs are manufactured with precision to meet API specifications or customized according to the client’s technical drawings and requirements.

Each sub is made from high-grade 42CrMo4 alloy steel, known for its excellent strength, toughness, and wear resistance—making it ideal for heavy-duty drilling environments. Advanced CNC machining ensures accurate thread profiles and consistent performance in the field.

Whether used for adapting drill rods, stabilizers, or other downhole tools, these threaded subs offer reliable performance and extended service life, even under high torque and pressure conditions.
