FAQ

1. What are the core advantages of JIS B1186 friction grip high-strength bolt set?

Different from traditional bolts that bear loads through shear force, this bolt set transfers loads via friction between connected steel plates, featuring higher connection strength, better stability and excellent slip resistance, ideal for core load-bearing joints serving long-term heavy-duty steel structure operations.

2. Can you provide complete product certification documents?

Yes, we can supply official MTR material test reports, mechanical performance test reports, factory certificates and other full-set documents to meet global engineering acceptance, customer audit and customs clearance requirements.

3. What is the function of HDG hot dip galvanizing finish?

As a globally recognized high-end anti-corrosion process, HDG greatly improves the rust and corrosion resistance of bolts. It adapts to harsh working environments including outdoor, coastal, humid and salt spray conditions, extending product service life and fitting various global construction scenarios.
