Import Din 933 Hexagon Head Bolts With Nuts And Washers — Buy in Bulk from Supplier in China

DIN 933 Full Thread Hex Bolts from Yongnian Yundu Fastener Co., Ltd. are produced in metric sizes from M6 to M30, with full threading extending the entire length of the bolt as required by DIN 933. The hex head dimensions conform to DIN 931 specifications, and the bolts are available in carbon steel grades 4.8, 8.8, and 10.9. Surface finishes include plain, zinc plated, and hot-dip galvanized, with plating thickness varying by application requirement.

These bolts are manufactured using cold heading and thread rolling processes, ensuring consistent grain flow and dimensional accuracy. Grade 8.8 is the most common for industrial use, offering a tensile strength of 800 MPa and a yield strength of 640 MPa. The inclusion of matching nuts and washers allows for complete fastening assemblies, with nuts conforming to ISO 4032 and washers to ISO 7089. The product is designed for applications requiring resistance to vibration and dynamic loads, such as in machinery and automotive frames.

Customers in the construction, rail, and heavy equipment sectors in Europe and North America use these bolts for structural and mechanical assemblies. Packaging is in sealed plastic bags inside cartons, with options for wooden crates for overseas shipments. Delivery terms include FOB Qingdao and CIF destination ports. Lead time is typically 20 to 30 days, depending on order volume and finish type. Buyers should confirm exact packaging and labeling requirements for customs compliance.

Yongnian Yundu Fastener Co., Ltd. is based in the Liuying Industrial Zone, Handan, Hebei, within the same regional hub as other major fastener producers. The supplier is listed as imported-tier, suggesting prior export experience and possibly compliance with international buyer requirements. There is no public information on company size, workforce, or production capacity. The listing references ISO and CE certifications but provides no documentation or certificate numbers.

Response metrics indicate zero response rate and zero average response hours, meaning no active communication on the platform. While the supplier claims compliance with international standards, buyers must independently verify all certifications and mechanical properties through third-party testing. The inclusion of nuts and washers in the product offering is a distinguishing feature, but compatibility must be confirmed with the supplier for each size and grade.
