Retaining Rings
Jiaxing Dongcheng Fastener Co.,Ltd offers retaining rings that are precision‑engineered fasteners for shafts and bores. The product range covers diameters from 3 mm up to 305 mm and is supplied in both external (DIN 471) and internal (DIN 472) configurations. Materials are stainless steel and carbon steel, with surface treatments such as phosphating, oxidation and zinc plating. All rings conform to DIN, JIS, ISO and GB standards.
Stainless‑steel rings are typically forged from AISI 304 grade, providing corrosion resistance in automotive and food‑processing equipment. Carbon‑steel variants commonly use AISI 1020, delivering high tensile strength for heavy‑duty machinery. Surface finishes improve wear resistance; phosphated coating is standard for oil‑field applications, while zinc plating offers sacrificial protection in humid environments. These characteristics align with standard industry expectations for snap‑ring performance.
The rings are widely used in automotive transmission assemblies, industrial gearboxes and equipment requiring axial retention. Importers seeking bulk hardware appreciate the cost‑effective pricing and the ability to order to custom dimensions. The supplier lists the product as a bulk industrial fastener from China, with standard packaging of 500 pieces per box. Buyers should confirm minimum order quantities, lead times and Incoterms directly with the supplier.

Sourcing Retaining Rings from Jiaxing Dongcheng Fastener Co.,Ltd - China Import Guide
Before placing an order, importers should request the supplier’s material test reports and certification copies that confirm compliance with DIN, JIS, ISO and GB standards. Verify the exact material grade, surface finish specifications and dimensional tolerance for the required ring size. Request a sample or a technical drawing to ensure the external or internal configuration matches the intended assembly. This due diligence reduces the risk of receiving non‑conforming hardware.
Discuss the preferred Incoterms with Jiaxing Dongcheng Fastener Co.,Ltd, such as FOB Suzhou port or CIF destination, to align shipping responsibilities. Ask for an estimated production lead time based on the required size and quantity, as the listing does not provide this information. Confirm the freight options, container loading plans and any required export documentation from China. Clear agreement on these terms streamlines the customs clearance process.
Arrange for a third‑party inspection before loading, focusing on material composition, surface finish quality and dimensional accuracy. Request the inspection report to include hardness measurements and visual checks for plating defects. Ensure that the supplier can provide a certificate of conformity and a mill test report for each batch. Incorporating these checks safeguards product performance in the downstream application.
