Flange Bolt Manufacturer | Custom High-Strength Bolts & Fasteners

Flange bolts are a critical fastener in many industries, characterized by a circular flange that acts as an integrated washer. This design provides a larger bearing surface, which distributes the clamping load over a wider area, reducing the likelihood of surface damage and loosening under vibration. As a specialized Flange Bolt Manufacturer, we understand the importance of precision and material integrity in producing these fasteners. Our manufacturing process begins with high-quality raw materials, which are then forged or cold-headed to create the desired shape. The flange is typically formed simultaneously, ensuring a seamless and robust structure. Subsequent CNC machining allows for tight tolerances on thread dimensions and flange flatness, which are essential for proper torque and sealing. We offer a range of flange bolts, including serrated flange bolts for enhanced locking, and flat flange bolts for general use. Surface treatments are applied to meet specific corrosion resistance requirements, such as zinc plating for indoor applications or hot-dip galvanizing for outdoor and marine environments. Our engineers work with clients to select the optimal material grade, thread type, and finish for their application, ensuring long-term performance and safety. With our extensive production capabilities, we can handle both small and large volume orders, delivering consistent quality and timely shipment worldwide.
