FAQ:
Q1: What is the main advantage of using a Flanged Hex Head Bolt over a standard bolt?
A: The main advantage is the integrated flange, which acts like a built-in washer. It distributes the clamping force over a larger surface area, which protects the mating surface and reduces the risk of the fastener loosening due to vibration.
Q3: Does this fastener comply with specific industrial standards?
A: Yes, this hex head bolt is manufactured adhering to the GB5789 standard, ensuring it meets specific requirements for large hexagon flange bolts.
Q3: Do I need a washer with this bolt?
A: No. The integrated flange replaces the need for a separate washer while offering stronger and more reliable fastening.
Q4: Where is this bolt commonly used?
A: It is widely used in automotive assemblies, construction structures, machinery equipment, marine hardware, and chemical processing industries.
Q5: Does the flange design prevent loosening?
A: Yes. The flange increases friction and reduces vibration-related loosening, making it ideal for dynamic or high-load applications.
