CASSING SCREWS

CASSING SCREWS – High-Precision Threaded Connectors for Bored Pile Systems

When it comes to foundation drilling, precision, strength, and reliability aren’t optional—they’re essential. The CASSING SCREWS (commonly referred to as casing screws) are critical components in bored pile operations, engineered to provide secure and vibration-resistant connections between casing tubes. These robust connectors serve as the mechanical backbone of casing string assemblies, ensuring uninterrupted drilling even in the most demanding geotechnical conditions.

Manufactured to the highest OEM standards by 3GEN Export, our CASSING SCREWS are compatible with a wide range of leading bored pile rig manufacturers including BAUER, LIEBHERR, SOILMEC, SANY, and XCMG.

What Are CASSING SCREWS?

Casing screws are heavy-duty, threaded components designed to join casing segments during rotary drilling and piling. Their primary function is to provide a reliable threaded lock between casing tubes, ensuring axial load transmission and preventing rotational slippage under high torque.

Their design is tailored to match exact casing geometries, typically featuring deep-thread profiles, fine surface finishes, and chamfered leading edges for easy alignment and torque application.
