Products Description
A Flanged Screw with Hexagonal Head is a high-performance fastener that integrates a hexagonal head with an integral flange structure. It is widely used in machinery, building structures, electronics, furniture manufacturing, and industrial assembly. The flange can directly replace gaskets, expanding the contact area for stress distribution, effectively distributing preload, and preventing loosening and damage to the workpiece surface. It is suitable for industrial environments with high requirements for connection stability, vibration resistance, and installation efficiency.
Key Structural Features
Integrated Flange Design
A forged or machined annular Threaded Fastener of Flanged Hexagon Head Bolt beneath the head replaces the separate gasket. Its diameter is precisely calculated to provide a larger bearing area than standard bolt heads without increasing the overall installation height.
Optimized Force Transmission Path
Unlike the traditional two-stage force transmission of "bolt + washer," the integrated design ensures that the torque applied to the Flanged Hexagon - Headed Threaded Bolt is more directly and evenly converted into clamping force on the connected parts through the flange, reducing energy loss and uncertainty in the force transmission process.
Enhanced Anti-Loosening Configuration
Many Fastening Screw with Flange and Hex Head integrate anti-slip textures such as serrations, knurling, or corrugations on the bottom surface of the Fastening Screw with Flange and Hex Head, creating a mechanical interlock with the surface of the connected parts, providing excellent resistance to vibration and loosening.
Manufacturing Process
Automotive Manufacturing and New Energy Vehicles
Hexagon Flange Headed Bolt Fasteners' excellent vibration resistance, anti-loosening properties, and protection of aluminum materials are crucial in engine accessories, chassis suspension, battery pack frames, and electrical box fixings. Automated assembly lines particularly benefit from the efficiency improvements brought by its consistency.
High-End Furniture and Sports Equipment
At connection points that frequently withstand dynamic loads and require aesthetic appeal, such as joints in fitness equipment and load-bearing connections in high-end furniture, Fastening Screw with Flange and Hex Heads' integrated design balances reliability, aesthetics, and ease of installation.
Steel Structures and Precast Buildings
At connection nodes that need to resist wind load vibrations or equipment operating vibrations, such as purlin connections and equipment platform fixings, Flanged Hexagon - Headed Threaded Bolts' anti-loosening performance provides a higher safety redundancy.
Detailed Showcase
Thread Details
The internal thread of Threaded Fastener of Flanged Hexagon Head Bolt undergoes double treatment of rolling and grinding, resulting in a smooth, burr-free surface, high meshing accuracy, and a tight fit with the nut. The thread inlet guide angle is designed to facilitate quick and precise meshing, improving assembly efficiency.
Flange Details
The Flanged Hexagon - Headed Threaded Bolt surface is flat and smooth, with fine and uniform anti-slip teeth. This ensures a good fit with the connected parts and enhances anti-loosening performance. The rounded chamfer at the transition between the flange and the bolt is natural, without sharp edges, preventing scratches on parts and reducing stress concentration.
Head Details
The external Fastening Screw with Flange and Hex Head has a flat contact surface and uniform wall thickness distribution, allowing for even torque transmission under load and preventing localized deformation. The head is firmly connected to the flange, free from defects such as incomplete welding or cracks, and can withstand tightening torque.
Surface details
The surface treatment coating is uniform and dense, free from defects such as bubbles and peeling, and has excellent corrosion resistance and adhesion; the product markings are clear, indicating information such as material, specifications, and production batch, which facilitates customer warehousing management and quality traceability.
