They are produced from carbon steel or alloy steel, with surface finishes including black oxide, zinc plating, hot-dip galvanizing, and YZP coating. Dimensions range from M5 to M36, with lengths from 25mm to 300mm, as specified in the product data. These bolts are precision forged and machined for consistent head geometry and thread accuracy.
The material composition follows standard ISO 898-1 for mechanical properties, with grade 8.8 and 10.9 being most common in structural applications. Surface treatments are applied to meet corrosion resistance requirements: zinc plating offers mild protection, hot-dip galvanizing provides heavy-duty durability, and YZP is a proprietary chromate-free alternative. These finishes are not cosmetic but functional, selected based on environmental exposure and industry norms in automotive and construction sectors.
These bolts are purchased by industrial distributors, OEMs in machinery manufacturing, and construction contractors sourcing bulk quantities for structural steel assembly. Packaging is in cartons of 36x24x16 cm or 36x24x12 cm, palletized on standard Euro pallets (110x80x90 cm). Lead time is typically 7 to 15 working days depending on order volume, and samples are available free of charge if in stock. Export is handled via Ningbo port under standard Incoterms such as FOB or CIF.

The listing confirms sample availability and production capacity for bulk export orders, but does not claim certifications, client names, or manufacturing automation levels.
The supplier focuses on metric fasteners, particularly DIN and ISO standard bolts, nuts, and washers. Response metrics are not active, suggesting no live chat or email automation. Their operational strength lies in production volume and export logistics rather than digital engagement. No claims are made about ISO certification, internal testing labs, or in-house plating lines. Buyers should treat this as a production-focused exporter with documented export capability but limited public transparency on quality systems.
DIN931 hex head bolts are precision-engineered metric fasteners widely used in industrial assembly, construction, and machinery applications. Available in grades 4.8 through 12.9 with carbon or alloy steel construction, these bolts feature options in BLACK, ZINC, HDG, and YZP finishes for corrosion resistance. As a core export fastener from China's manufacturing hubs, they are sourced in bulk by distributors and OEMs for structural steel work, automotive assembly, and heavy equipment production.

Before placing an order, verify the exact grade and surface finish required for your application. Confirm that the material composition matches ISO 898-1 for mechanical properties and that the coating type (e.g., YZP vs. zinc) meets your environmental exposure needs. Request a sample for fit and finish inspection, especially if the bolts will be used in critical assemblies. Do not assume compliance with international standards without documented test reports.
Lead time is typically 7 to 15 working days, but this depends on order volume and current production load. Incoterms are usually FOB Ningbo, though CIF and CFR are negotiable. Payment terms commonly require 30% advance and 70% against copy of B/L. Confirm packaging specifications with the supplier - carton dimensions and palletization must align with your warehouse and shipping equipment. Request a packing list with batch numbers for traceability.
Quality checks should include dimensional verification using calipers and thread gauges, hardness testing on representative samples, and visual inspection for surface defects. Request a Certificate of Conformity (CoC) with each shipment, referencing DIN 931 and the specified grade. For corrosion-sensitive applications, ask for salt spray test results or coating thickness measurements in microns. Document all inspection findings and retain samples for potential claims.
