FAQ

Q1 Does the marine environment require special protection?

A: Triple protection is required: hot dip galvanizing (≥80μm) + chromate passivation + sealant coating. Salt spray test needs to pass 2000 hours without red rust .

Q2 What are the common causes of bolt breakage?

A: There are three main causes:
1. over-torquing installation (more than 30% over the nominal value)
2. Repeated use of more than 50 cycles
3. Thread wear due to intrusion of sea sand

Q3 Is it possible to replace the bolt with a common bolt?

A: Absolutely prohibited! Ordinary bolts:
Insufficient strength (Grade 4.8 only)
No corrosion-resistant treatment
Mismatch in thread accuracy
May lead to catastrophic accidents

Q4 How can I check the life of bolts?

A: Three types of monitoring are performed:
1. Magnetic particle inspection for micro cracks 2.
2. Through-gauge for thread wear
3. Hardness test (HRC22-34 range)
Immediate scrapping if any of the indicators exceeds the limit.
