Threading

Precision Steel Threading Services | CNC Pipe & Rod Threading

Threading is a vital machining process that creates helical grooves (threads) on the surface of steel components, enabling secure fastening, fluid sealing, and mechanical connection in countless applications.

At our facility, we provide custom steel threading services with exceptional precision, covering both internal threading (tapping) and external threading (thread cutting) to meet diverse industrial requirements. By employing CNC threading machines, thread rolling equipment, and advanced cutting tools, we ensure consistent quality, durability, and compatibility with global standards such as ISO, ANSI, DIN, and BS.

Our threading solutions are widely applied in steel pipes, bolts, flanges, couplings, hydraulic fittings, and mechanical parts, ensuring strong and reliable connections even under high pressure, high temperature, or corrosive environments. With strict quality inspection and advanced measurement techniques, we guarantee tight tolerance, smooth surface finish, and long service life for every threaded product.
