DIN931 Hexagon Head Bolts
DIN931 hexagon head bolts from Ningbo Steel Bolt Co., Ltd are half-threaded, metric fasteners manufactured to DIN 933 standards, with material options in carbon steel and stainless steel. Grades available include 4.8, 6.8, 8.8, 10.9, and 12.9, with surface treatments such as hot-dip galvanizing, zinc plating, Dacromet, black oxide, and plain finish. These bolts are designed for structural connections where an unthreaded shank is needed to reduce stress concentration and improve shear resistance.
The half-threaded design follows DIN 933 specifications, with the unthreaded portion typically equal to twice the nominal diameter plus 5mm. Heat treatment is applied to grades 8.8 and above to meet tensile and yield strength requirements. Dacromet coating, a zinc-flake system, provides superior corrosion resistance compared to standard plating and is often selected for marine or outdoor applications. Stainless steel variants are not specified by grade but are typically AISI 304 or 316 for corrosion resistance.
These bolts are sourced by machinery manufacturers, bridge construction firms, and OEMs requiring precision structural fasteners. Packaging is customizable, with standard pallets used for bulk shipments. Lead times are not stated but are implied to be competitive. Buyers should confirm whether the supplier uses automated threading and heat treatment lines, as this affects consistency. Export is handled via Ningbo port, with standard Incoterms applicable.

Sourcing DIN931 Hexagon Head Bolts from Ningbo Steel Bolt Co., Ltd - China Import Guide
Verify the exact standard being supplied - DIN 933 requires half-threaded bolts, while DIN 931 is fully threaded. Confirm the unthreaded shank length matches your assembly design, as this affects load distribution. Request material certificates for stainless steel variants and ensure surface treatments are specified by type (e.g., Dacromet vs. zinc). Do not assume compliance without documentation, even if the product name matches the standard.
Lead time is not specified but is described as competitive; confirm actual production and shipping timelines in writing. Incoterms are typically FOB Ningbo, but CIF and CFR are negotiable. Payment terms often require 30% advance and 70% against shipping documents. Packaging must be confirmed for pallet dimensions and carton labeling. Request batch numbering and packing lists to support traceability and quality audits.
Conduct incoming inspection using thread gauges, calipers, and hardness testers. For coated bolts, check coating uniformity and adhesion with tape tests. Request salt spray test results for corrosion-resistant finishes and ensure the supplier provides a Certificate of Conformity referencing DIN 933 and the stated grade. Retain samples from each shipment for potential disputes. Document all findings and compare against the original purchase specifications.
