Customer Questions & Answers

  • Question: What are M6 x 50mm flange bolts used for in scooters and ATVs?

    Answer: M6 x 50mm flange bolts are commonly utilized in the assembly of various components in scooters and ATVs, especially in the crankcase area. They provide a reliable fastening solution, ensuring that parts like the engine and transmission are securely held together. With their wider, integrated flange, they distribute loads evenly, reducing the risk of damage and wear over time. For example, these bolts are essential for maintaining the structural integrity of QMB139 engines in 50cc and 150cc models.
  • Question: Can I use M6 x 50mm bolts in other applications outside of scooters?

    Answer: While primarily designed for scooters and ATVs, M6 x 50mm flange bolts have versatility that makes them suitable for various applications, including motorcycles, go-karts, and even certain automotive repairs. Their strength and corrosion resistance ensure reliability in many environments. However, it's vital to ensure that the specifications match the requirements of your specific project to avoid any fitting issues.
  • Question: How do I install M6 x 50mm flange bolts correctly?

    Answer: To install M6 x 50mm flange bolts effectively, first, align the components that need fastening. Insert the bolt through the holes, ensuring the flange sits against the surface. Use a socket or wrench to tighten the nut securely, applying steady pressure without over-tightening, to avoid stripping the threads. This method guarantees a snug fit, essential for the operational stability of engine parts in scooters and ATVs.
  • Question: What materials are M6 x 50mm flange bolts typically made from?

    Answer: M6 x 50mm flange bolts are frequently made from high-quality steel with a zinc coating for enhanced corrosion resistance. This material choice ensures durability and longevity, making them suitable for use in outdoor and high-wear environments typical in scooters and ATVs. For enhanced performance, some might feature additional treatments, like black oxide or stainless steel variants, which provide even greater protection against rust.
  • Question: What is the thread pitch for M6 x 50mm flange bolts?

    Answer: The M6 x 50mm flange bolts come with a standard thread pitch of 1.0 mm. This pitch is crucial for compatibility with various components in scooters equipped with QMB139 engines and similar setups. Using the correct thread pitch ensures that the nuts and bolts fit together correctly, providing a secure fastening solution that withstands vibration and load during operation.
  • Question: How many flange bolts do I need to replace in my scooter's crankcase?

    Answer: The number of M6 x 50mm flange bolts required for replacing those in your scooter's crankcase usually depends on the engine design. Generally, a single crankcase may use several bolts, often ranging from 6 to 10. It’s advisable to consult your scooter's manual or manufacturer for the exact number to ensure proper and even distribution of pressure, which is crucial for engine function.
  • Question: Are M6 x 50mm flange bolts universal or specific to certain brands?

    Answer: While M6 x 50mm flange bolts can fit various scooter and ATV brands, they are often intended for specific models, such as those with QMB139 engines or GY6 motors. It's essential to confirm compatibility with your scooter's model specifications before purchasing. Checking manuals or manufacturers’ guidelines ensures you get the right components to maintain performance and safety.
  • Question: Where can I find M6 x 50mm flange bolts for my scooter?

    Answer: For purchasing M6 x 50mm flange bolts, your best option is Ubuy, where you'll find a selection suited for QMB139 50cc and 150cc motors. Ubuy offers a convenient online shopping experience, allowing you to browse various options and make a well-informed decision. With detailed product descriptions, you'll ensure that you are buying the correct parts for your Chinese scooters and ATVs.
  • Question: Can I use these bolts with different engine sizes?

    Answer: M6 x 50mm flange bolts can be utilized across different engine sizes, particularly in setups like 50cc and 150cc QMB139 and GY6 motors. As long as the thread specifications and sizing match, you can adapt these bolts to fit various applications without issues. However, be cautious about load-bearing needs since engine designs might vary in component stress points.
  • Question: What is the benefit of using flange bolts over regular bolts?

    Answer: Flange bolts, such as the M6 x 50mm type, offer significant advantages over standard bolts due to their wider, integrated flange design. This feature provides a larger bearing surface that helps prevent loosening from vibration and protects the underlying material from wear. This makes them particularly valuable in high-vibration environments like scooter and ATV engines, ensuring secure fastening and better overall durability.
