Frequently Asked Questions (FAQ)
Q1: What is the difference between Grade 8.8 and 10.9 for a bolt machine hex head?
A: The grade indicates the tensile strength. A Grade 8.8 bolt has a minimum tensile strength of 800 MPa and a yield strength of 640 MPa. A Grade 10.9 bolt is stronger, with a minimum tensile strength of 1000 MPa and a yield strength of 900 MPa. Choose 10.9 for higher-stress, critical applications.
Q2: Can you provide bolts with specific thread lengths?
A: Absolutely. While we stock standard partially-threaded and fully-threaded bolts, we specialize in custom manufacturing. You can specify the exact thread length (e.g., 40mm of thread on a 100mm shank) to meet your engineering requirements.
Q3: What finish do you recommend for outdoor marine environments?
A: For highly corrosive environments like marine applications, we strongly recommend Hot-Dip Galvanized or Dacromet coatings. These provide a thick, sacrificial barrier offering superior long-term protection against saltwater corrosion compared to standard zinc plating.
Q4: What are your packaging and minimum order quantities (MOQ)?
A: Standard packaging is in carton boxes or steel drums, clearly labeled by size and grade. We offer flexible MOQs, with competitive pricing for both sample orders and large-volume container shipments. Contact our sales team for a precise quote based on your needs.
Q5: How do I ensure I'm ordering the correct bolt machine hex head for my application?
A: Provide our team with the key parameters: required diameter, length, strength grade, material, and finish. If you have technical drawings or specifications (ISO/DIN/ASTM), sharing those is the best way to ensure accuracy. Our experts are here to assist in the selection process.
