1. Material: 45# carbon steel
2. Manufacturing Process: CNC lathe cutting, milling on a milling machine, and precision turning for surface finishing.
3. Dimensional Features: The component features an annular, thick-walled nut‑type structure; its inner wall is machined with a continuous internal thread for secure threaded engagement with external‑threaded fittings and sleeves. The outer circumference is evenly milled with multiple flat clamping surfaces, enabling precise alignment and secure tightening using open‑end wrenches or pipe wrenches. With sufficient wall thickness, it resists deformation under clamping forces, while its flat end face ensures tight contact with sealing gaskets, achieving a reliable seal and lock.
4. Surface Treatment: Blackening, Galvanizing for Rust Prevention
5. Product Applications: Primarily used for hydraulic valve body lock nuts, pipeline sealing retaining rings, vacuum chamber cover nuts, and spindle limit‑stop fasteners on equipment. It achieves rapid, secure sealing via internal threads and is widely employed in hydraulic piping systems, fluid‑handling equipment, and automated sealing modules.
