Import Din 933 Full Thread Hex Bolts — Buy in wholesale FOB from Supplier in China

DIN 933 Full Thread Hex Bolts from Handan Haosheng Fastener are manufactured to meet the DIN 933 standard for fully threaded hexagon head bolts, with thread lengths matching the nominal length of the bolt. Available in metric sizes from M5 to M24, these bolts feature a hexagonal head with a nominal width across flats as defined in DIN 933, and are typically produced in carbon steel grades 4.8, 8.8, and 10.9. The surface finish is either plain or zinc plated, depending on order requirements, with plating thickness conforming to ISO 4042 for corrosion resistance.

These bolts are commonly made from low to medium carbon steel, with mechanical properties aligned with ISO 898-1. Grade 8.8 is the most frequently ordered for industrial applications due to its balance of tensile strength and ductility, while grade 10.9 is selected for high-stress environments. The full threading allows for greater engagement in tapped holes or with nuts in confined spaces, making them suitable for machinery assembly and structural connections where partial-threaded bolts are impractical. The manufacturing process includes cold heading and thread rolling, consistent with industry best practices for dimensional accuracy and surface finish.

Buyers in the construction, machinery, and automotive sectors across Europe and Southeast Asia source these bolts for structural assemblies requiring reliable, repeatable fastening. Packaging is typically in bulk cartons of 20 to 50 kg, with options for polybagged individual sets or wooden pallets for large orders. Lead times are generally 15 to 25 days after order confirmation, and delivery terms are commonly FOB Xingang or CIF destination port. Free samples are available upon request for quality verification before bulk procurement.

Handan Haosheng Fastener operates from the Southwest of Yongnian Development Zone in Handan, Hebei, a region known for its concentration of fastener manufacturers. The supplier identifies as a producer of hex bolts and nuts with over 20 years of export experience, shipping primarily to Europe, the Middle East, and Southeast Asia. There is no public information on company size, annual output, or client list. The listing states no certifications beyond ISO9001-2008, which is not independently verified in the source data.

Response metrics show zero response rate and zero average response hours, indicating no active engagement on the platform. The supplier's trust tier is listed as harbor, suggesting basic platform verification but no third-party audit or inspection history. Buyers should treat this as a direct manufacturer with no public quality assurance documentation beyond its self-reported claims. Product consistency must be confirmed via physical samples prior to large orders.
