For patio doors, garden gates, or modern interior doors, our aluminum bolts provide peace of mind. They withstand the elements outdoors while maintaining their sleek look indoors, offering reliable security without compromising on style.
We specialize in the OEM manufacturing of high-quality motorcycle exhaust clamps. Our products are engineered to ensure secure connections, superior vibration resistance, and long-term durability under high-temperature conditions. Utilizing advanced materials and precision processes, we offer customizable solutions to meet specific design requirements and international standards. Ideal for exhaust system manufacturers and aftermarket brands seeking reliable components.
Manufactured from 304 or 316 grade stainless steel, our gears offer exceptional strength, corrosion resistance, and longevity. They are ideal for applications exposed to moisture, chemicals, extreme temperatures, or requiring stringent hygiene standards, such as in food processing, medical devices, marine engineering, and automotive systems. These gears maintain dimensional stability under load and are capable of withstanding harsh operating conditions.
Our brass gears are machined from high-quality, lead-free brass alloy, ensuring excellent corrosion resistance and smooth operation. Ideal for precision instruments, clockwork mechanisms, and decorative applications, these gears offer a perfect blend of classic aesthetics and modern reliability.
Advantages
Anti-loosening and vibration resistance: The serrated structure creates a locking effect, which can resist vibrations and ensure a stable connection.
Corrosion resistance: The colored zinc coating has excellent anti-rust properties (for example, no white rust appears within 48 hours, and no red rust appears within 72 hours).
Protects the surface: The integrated flange plate acts as a gasket, which can disperse pressure and reduce damage to the connection surface.
Installation convenience: This design is easy to install quickly and can be reused in some cases, thereby improving maintenance efficiency.
Cost-effectiveness: Compared to adding separate gaskets or locking nuts, it provides an economical and efficient anti-loosening solution.

Our stainless steel universal joints provide reliable angular power transmission while offering excellent corrosion resistance. Perfect for applications requiring flexibility and durability in harsh environments.
Our stainless steel round head screws feature a smooth, domed head design that provides a finished appearance while minimizing snagging. Made from grade 304 or 316 stainless steel, these screws offer excellent corrosion resistance for indoor and outdoor applications. Ideal for furniture, machinery, and marine equipment.
Our high-precision pulley kits are engineered for critical motion control applications requiring accurate and synchronous power transmission. These kits typically include precisely matched timing pulleys and belts, designed to eliminate slip and maintain perfect synchronization between shafts. Manufactured to exacting tolerances from materials such as aluminum, steel, or plastics, our pulley kits ensure minimal vibration, reduced noise, and long-term reliability. They are ideal for use in robotics, CNC machinery, medical devices, and automated equipment where positioning accuracy is paramount.
Achieve peak performance in your drive systems with our custom-made precision spur gears and helical gears. Our spur gears offer cost-effective power transmission with high efficiency, while our helical gears provide smoother operation and greater load-bearing capacity under high-speed conditions. Every gear is tailored to your exact specifications—from material selection (including steel, brass, and plastics) to heat treatment and finishing. Partner with us for reliable, quiet, and durable gear solutions that minimize backlash and maximize power transmission efficiency.
