Ensuring the structural integrity of truck and car transmission systems with high-grade fastening technology.
In the modern automotive landscape, the Clutch Flywheel Bolt is not merely a fastener; it is a critical safety and performance component. As engines become more powerful and torque outputs increase, the stress on the connection between the crankshaft and the flywheel has reached unprecedented levels. Globally, the demand for high-tensile flywheel bolts (typically Grade 10.9 or 12.9) is surging, driven by the expansion of the logistics sector and the requirement for long-haul heavy-duty trucks.
The industrial status of flywheel bolts has shifted towards "Precision Fastening." Leading manufacturers in China, such as Zhejiang TVC Auto Co., Ltd., are now utilizing advanced cold-forging and vacuum heat treatment to ensure these bolts can withstand extreme vibration and thermal cycles. Market analysts observe that the European and North American markets are increasingly looking to China for "Tension-Control" specialized bolts that offer the same reliability as German or American counterparts but at a significantly optimized cost structure.

With the rise of EVs and hybrid trucks, there is a trend toward high-strength alloy bolts that offer weight reduction without compromising shear strength. Our R&D team is pioneering titanium-alloy composites for racing applications.
Industry 4.0 has introduced ultrasonic tension measurement. Modern China factories are now providing bolts with specialized surface coatings that allow for better friction coefficient control during automated assembly.
Moving away from traditional chrome plating, we adopt Zinc-Flake coatings (Geomet/Dacromet) which offer superior corrosion resistance and are compliant with global environmental REACH and RoHS standards.
Our History: established to become an independent, specialized company focused on manufacturing clutch parts. After more than ten years of continuous effort, the company has grown into a significant player in the industry. Led by renowned experts, researchers, and senior engineers in clutch manufacturing, we take responsibility for technology, quality management, product development, and sales. Our management team, with expertise in manufacturing, production, logistics, procurement, and equipment management, has built three major product lines (light, medium, and heavy) covering a wide range of products.
Our Factory Expertise: Zhejiang TVC Auto Co., Ltd. specializes in the research, development, production, and sales of clutches for light, medium, and heavy trucks. Our products are suitable for various truck models and use high-quality raw materials from reputable suppliers to ensure top standards. We manufacture over 90% of our clutch parts in-house, all of which pass national authority testing. We are committed to delivering products on time with high efficiency, and our prices are highly competitive in the market. Since our inception, we have strictly implemented the ISO/IATF16949: 2016 quality control system.
The procurement needs of global enterprises have evolved. Today, Tier-1 suppliers and aftermarket distributors are looking for Turnkey Fastening Solutions. For instance, in the Middle Eastern market, heat resistance is paramount due to high ambient temperatures, whereas in Northern Europe, anti-corrosion against road salts is the priority.
Long-haul logistics companies require flywheel bolts that guarantee zero-failure over 500,000 miles to prevent catastrophic engine and transmission damage.
Tractors like the FIAT and MF series operate under high-torque, low-speed conditions where vibration loosening is a constant threat. Our self-locking bolt designs are ideal here.
Mining trucks from Volvo and Scania require specialized dual-clutch flywheel fasteners that can handle the massive inertia of heavy loads.
China has built the world's most complete automotive supply chain. When you partner with a factory like TVC Auto, you are benefiting from Vertical Integration. From raw steel sourcing to final surface treatment, every step is controlled within a 50km radius, reducing lead times and logistical costs. Furthermore, our ability to provide Custom Sizes (OEM/ODM) for legacy engines (like Hino W04D or Isuzu 8-97034) ensures that even niche markets are served with precision-engineered parts.
Technical compatibility audits and detailed performance data sheets for every bolt and clutch part.
Real-time logistics tracking and active feedback loops to ensure the products meet your assembly line needs.
24/7 engineering support and rapid response solutions to ensure 100% customer satisfaction across all continents.
Through our commitment to quality and reliability, TVC Auto has earned a solid reputation in the automotive industry and has become a trusted partner for Top China Clutch Flywheel Bolts worldwide.
