Cross-standard compatibility analysis between Grade 10.9 Hex Head Full Thread Bolts

Here is the cross-standard compatibility analysis between GB/T 5783-2016 and other international standards for Grade 10.9 Hex Head Full Thread Bolts M10, formatted as a comparative table:

GB/T 5783-2016 vs. International Standards Compatibility Table

Technical Notes

1. Equivalent Standards:

   • ISO 4014 and JIS B1180 are functionally interchangeable with GB/T 5783-2016 in terms of strength and dimensions.
   • Minor material differences (e.g., 42CrMo4 vs. 35CrMo) do not affect mechanical performance.

2. Reference Standards:

   • DIN 933: Requires verification of coating thickness (DIN 267-10 vs. GB/T 5267).
   • ASME B18.2.3.5M: Not directly interchangeable due to inch vs. metric threads (3/8" ≈ 9.525mm vs. M10).

3. Critical Applications:

   • For structural bolting (e.g., bridges, machinery), use ISO 4014 or JIS B1180 as direct replacements.
   • Avoid substituting ASME B18.2.3.5M unless thread compatibility is confirmed.

4. Certification Requirements:

   • ISO 898-1 (metric) and ASTM F3125 (ASME) define testing protocols. Ensure third-party certification matches the target standard.
