THREAD RING

THREAD RING – Precision Threaded Coupling Component for Bored Pile Systems

The THREAD RING is a compact yet critical component used in bored pile foundation systems, responsible for secure and stable threading of casing segments, tools, or accessories. Despite its minimal appearance, this high-precision ring plays a foundational role in ensuring torque transmission, centering accuracy, and locking reliability in rotary drilling operations. It serves as a connection interface between casing pipes, auger extensions, Kelly bars, or adapter elements—especially for large-diameter systems.

3GEN Export offers THREAD RING models that are OEM-compliant, manufactured under strict tolerances to match the operational demands of BAUER, LIEBHERR, SOILMEC, SANY, and XCMG drilling rigs.

What Is a THREAD RING?

The THREAD RING is a threaded circular adapter ring designed to align and lock screw-type drilling tools and casings into place. Typically fitted between Kelly boxes, casing adapters, or conical joints, it ensures that your connections remain stable even under high torque and vibration conditions. The robust build and internal threading geometry allow for fast and repeatable engagement and disassembly, which is essential for projects that demand modular tool changes on-site.

It’s often seen on casing shoes, drive adapters, and core barrels, helping eliminate misalignment and premature wear of mating parts.
