7. Frequently Asked Questions (FAQ)
Q1: What is the difference between Property Class 8.8 and 10.9 for a 6mm hex bolt?
A: Property Class indicates the tensile strength of the bolt. A Class 8.8 bolt has a minimum tensile strength of 800 MPa and a yield strength of 640 MPa. A Class 10.9 is stronger, with 1000 MPa tensile and 900 MPa yield strength. Choose 10.9 for higher-stress, critical applications.
Q2: Are your stainless steel 6mm hex bolts suitable for marine environments?
A: Our A4-80 (316 stainless steel) 6mm hex bolts offer excellent resistance to saltwater corrosion and are highly recommended for marine and coastal applications. For severe marine conditions, we advise consulting our technical team.
Q3: Can I order custom lengths or non-standard finishes?
A: Yes. We specialize in providing customized fastening solutions. We can manufacture 6mm hex bolts in specific lengths, special thread pitches, and with custom finishes (e.g., dacromet, geomet) based on your project's MOQ. Contact our sales team with your specifications.
Q4: What packaging options are available for bulk orders?
A: We offer industry-standard packaging including 1kg/5kg boxes, 25kg cartons, or customized palletized packing. All packaging is designed to prevent damage and corrosion during transit and storage.
Q5: How do I ensure I'm ordering the correct 6mm hex bolt for my application?
