Products Description
With its unique structure of a hexagonal head plus an integrated flange base, the Hexagon Head Flange Bolt Screw combines the functions of a bolt and a washer into one unit. It delivers a stronger locking force, better anti-slip performance, and higher assembly efficiency, making it the preferred fastener for applications requiring high vibration resistance, heavy load capacity, and high reliability.
We specialize in the R&D and large-scale production of high-quality flange bolts, strictly in compliance with international standards. We maintain independent control over the entire production chain, from materials and heat treatment to forming and surface finishing. We provide stable, reliable, and long-term bulk supply solutions of flange bolts for global engineering customers, equipment manufacturers, and foreign trade purchasers, helping customers improve assembly efficiency, reduce failure rates, and enhance product competitiveness.
Product Advantages
Integrated Flange Structure
The flange base of the Flange - Equipped Hexagon Head Bolt is integrally formed with the bolt head. No additional flat washers or spring washers are required, reducing the number of components and simplifying the assembly process, which greatly improves production and installation efficiency. It is especially suitable for high-volume applications such as assembly lines, construction machinery and vehicle assembly.
Excellent Anti-Slip and Anti-Loosening Performance
The bottom surface of the flange is usually designed with anti-slip serrations, which greatly increase the friction of the Hex - Headed Bolt with Flange Attachment. It can resist vibration, impact and alternating loads, reducing the risk of loosening. It is widely used in high-vibration applications such as engines, chassis and construction machinery.
Large Pressure-Bearing Area
The flange plate of the Hexagon Flange Head Machine Screwsw expands the contact area, allowing the clamping force to be distributed evenly. This avoids substrate deformation, cracking and wear caused by excessive local pressure, and extends the service life of equipment and structures.
Strong Universality
The Hexagonal Head Screws Featuring Washers is manufactured in accordance with international standards in terms of size, strength and material. It can directly replace standard parts from various countries and is compatible with different equipment and working conditions, making it a globally universal and highly reliable fastening solution.
Application Scenarios
Automotive & Construction Machinery
Engines, chassis, frames, gearboxes, as well as heavy‑duty equipment such as excavators, loaders and rollers rely on Washer-equipped Hexagon Head Screws as core safety fasteners for anti‑slip and anti‑loosening performance. Its one‑piece structure eliminates the need for extra gaskets, combining convenience and safety. It withstands high‑frequency vibration during equipment operation, eliminates the risk of loosening, and ensures long‑term stable performance.
Heavy Machinery & Machine Tools
Hexagonal Head Screws Having Washers is used for securing machine tool bases, spindle components, hydraulic equipment, speed reducers and electric motors. The flange surface protects the mounting face from compression damage. It is compatible with various wrenches to improve assembly efficiency, distributes clamping force evenly, adapts to continuous torque during operation, prevents mounting surface wear, and maintains equipment precision.
Vehicle Manufacturing & Components
Hex Head Screw with Washer Assembly is applied in the frame and chassis assembly of passenger cars, trucks, new energy vehicles and electric vehicles. The one‑piece structure boosts production line efficiency, meets automated mass assembly requirements, and reduces part count and assembly processes. Its anti‑slip and anti‑loosening design resists vibration and impact during driving, balancing production efficiency and driving safety.
Home Appliances, Motors, Fans & Pumps
Hexagon Head Fasteners with Built-in Washers Hexagonal is ideal for fan casings, pump flanges, compressors and air conditioning units, especially in high‑vibration environments. It effectively prevents bolt loosening and ensures stable operation. The flange protects thin substrates from cracking, adapts to humid and outdoor conditions, simplifies assembly procedures and improves productivity.
