2. Manufacturing Process: Round steel is sawed to length, then turned on a lathe for rough external and internal turning; followed by precision turning of the trapezoidal threads and end faces, with final grinding; strict control of end-face flatness.

3. Dimensional Features: The component features an overall flat, large‑disc design; its center incorporates a through‑threaded bore with a step, intended for threaded connections to pipelines or shafts; the outer ring is equipped with a thick‑walled flange, around whose periphery multiple bayonet‑type locking slots are evenly spaced; the end face is smooth and flat, making it suitable for the installation of sealing gaskets to achieve gas‑tight and liquid‑tight assemblies.

4. Surface Treatment: Blackening, Galvanizing for Rust Prevention

5. Applications: Commonly used for hydraulic valve bonnets, pipeline sealing flanges, spindle locking pressure plates on equipment, and vacuum chamber covers. The central threaded design enables quick tightening and sealing, while the peripheral retaining groove facilitates wrench or tool‑based disassembly and positioning. Widely employed in hydraulic systems, fluid‑handling pipelines, and heavy‑duty automated machine tools.
