Frequently Asked Questions (FAQ)
Q1: What is the difference between a Grade 8.8 and a 10.9 30mm hex bolt?
A: The grade indicates the bolt's tensile strength. A Grade 10.9 bolt has a higher minimum tensile strength (1040 MPa) than a Grade 8.8 bolt (830 MPa), making it suitable for more critical, high-stress applications. Material composition and heat treatment processes differ to achieve these strength levels.
Q2: Can I get a 30mm hex bolt in a corrosion-resistant material for outdoor use?
A: Absolutely. For outdoor or corrosive environments, we recommend A4-80 (316) stainless steel or carbon steel bolts with a hot-dip galvanized (HDG) finish. These options provide excellent resistance to rust and weathering.
Q3: Is the 30mm length measured including the head?
A: No. The standard length measurement for bolts like the 30mm hex bolt is taken from the underside of the head to the very end of the shank. The height of the head is not included in this nominal length.
Q4: Do you supply matching nuts and washers with these bolts?
A: Yes, we can supply full fastener kits. We offer hex nuts, flat washers, and spring lock washers in corresponding grades and finishes to ensure a perfectly matched, high-performance assembly.
Q5: What is your minimum order quantity (MOQ) for the 30mm hex bolt?
A: Our MOQ is flexible to accommodate both small pilot projects and large-scale ongoing needs. We offer competitive pricing for bulk industrial orders. Please contact our sales team for a specific quote based on your diameter, grade, and quantity requirements.
