DIN933 hex bolts from SPMC Shanghai Prime Macinery Co., Ltd. are manufactured to meet international DIN standards, with a focus on mechanical precision and consistent performance in industrial environments. The bolts are produced in carbon steel and stainless steel variants, with standard sizes ranging from M6 to M48. Surface treatments include zinc plating and hot dipped galvanizing, with grade options up to 12.9. The supplier emphasizes compliance with international standards but does not disclose specific production volumes.
The carbon steel variants conform to ISO 898-1, with mechanical properties verified for tensile and yield strength. Stainless steel versions are typically made from A2 or A4 material, providing corrosion resistance suitable for marine or chemical exposure. The head geometry follows DIN 933 specifications, with a hex head height of 0.6d to 0.7d and thread length defined as 2d for sizes up to M20. Tolerances for dimensions and thread pitch align with ISO 2768-1.
These bolts are used in automotive assembly, structural steel connections, and heavy machinery where high clamping force and vibration resistance are required. Buyers include OEM manufacturers, maintenance contractors, and engineering firms sourcing replacement components. Packaging is bulk-oriented for containerized shipment. Delivery timelines and trade terms are not specified in the source and must be confirmed directly.

Verify the exact grade and material specification before ordering, as DIN933 bolts labeled as 10.9 or 12.9 must meet ISO 898-1 mechanical requirements. Request material test reports for tensile strength, hardness, and chemical composition. Confirm surface finish thickness with a coating gauge, especially for zinc plating, as inadequate coating leads to premature corrosion in humid environments.
Lead time is not stated in the listing; confirm production and shipping timelines directly. Incoterms such as FOB Shanghai or CIF destination must be clarified, as they determine cost and risk transfer. Payment terms are not specified - T/T in advance or L/C are typical for new suppliers. Ensure packaging is moisture-sealed if shipping to humid climates to prevent rust.
Conduct incoming inspection using thread gauges, torque testing, and visual checks for surface defects. Measure coating thickness with a magnetic gauge and perform a salt spray test if corrosion resistance is critical. Retain a sample from each shipment for quality comparison. Request an inspection certificate from a third-party inspector if the order exceeds 5 metric tons.
