Frequently Asked Questions

Q1: What nuts match JIS B1186 F10T HDG High Strength Structural Hex Bolt?

A: JIS B1186 F10T HDG High Strength Structural Hex Bolt must be paired with Japanese F10 grade heavy hex nuts. Using the matched assembly ensures overall structural strength and stability of friction connection. Mixing ordinary GB or ASTM fasteners is not recommended.

Q2: Can you supply material test certificates?

A: Yes. Official MTC material reports and mechanical performance test reports can be provided for every batch to support project acceptance and third-party inspection.

Q3: Is customization available for surface finish and bolt marking?

A: Custom service is available. Surface treatments such as hot dip galvanizing, black oxide and dacromet can be customized. Custom head marking including customer logo, standard and grade stamp is also supported.

Q4: Are products in stock and can you handle large orders?

A: Regular sizes are kept in stock. The factory has sufficient production capacity to steadily fulfill large-volume foreign trade orders and long-term supply for engineering projects.
