Import Eye Bolt Screw Din 580 Lifting Eye Bolt — Buy in wholesale FOB from Supplier in China

The Eye Bolt Screw DIN 580 from Wudi Zhibo Metals Co., Ltd. is manufactured in marine grade stainless steel 304 or 316, with a threaded shank designed for direct screw-in installation into threaded holes. The eye has a smooth, rounded profile with no sharp edges, and the screw thread follows DIN 580 dimensional standards for consistent engagement with matching nuts or tapped components. This product is not plated or coated; the material itself provides corrosion resistance, making it suitable for continuous exposure to salt spray, humidity, and industrial atmospheres.

Stainless steel 304 offers good resistance to most atmospheric and chemical environments, while 316 adds molybdenum for enhanced performance in chloride-rich settings such as coastal or offshore applications. The manufacturing process includes investment casting followed by precision machining and surface polishing to ensure dimensional accuracy and surface finish. These bolts are not cold forged or stamped; the casting method allows for complex geometries and consistent grain structure under load. Typical tensile strength for 304 is 515 MPa minimum, and for 316 it is 520 MPa minimum, in line with ISO 3506 standards for stainless fasteners.

This product is commonly purchased by importers in shipbuilding, offshore wind farm construction, heavy machinery manufacturing, and railway infrastructure projects. Buyers typically require batch certification of material grade and dimensional compliance. Packaging is done in polyethylene-lined cartons, with 100 to 500 pieces per box depending on size. Minimum order quantities are not stated in the listing and must be confirmed directly with the supplier. Lead times vary based on production scheduling and are not guaranteed without written agreement.

Wudi Zhibo Metals Co., Ltd. operates a dedicated investment casting foundry and machining workshop located in Binzhou, Shandong Province, China. The company produces rigging hardware including eye bolts, shackles, turnbuckles, and marine fittings using stainless steel 304 and 316. Their capability includes custom casting from customer drawings, but the listing does not confirm ISO certification, third-party testing, or in-house quality labs. Response rate and average response time are not tracked in the system, indicating limited digital engagement but no evidence of operational inactivity.

The supplier does not claim years in business, revenue figures, or client names. They state they focus on quality and customer collaboration, but no awards, export volume data, or production capacity metrics are provided. Their identity is verified by a physical address and product manufacturing capability, not by third-party audits. Buyers should request sample pieces and material test reports before placing bulk orders.
