Key Features
- M5 Metric Specification — This set screw conforms to M5 metric sizing, making it compatible with a wide range of HOBAO RC vehicles and aftermarket RC car parts, ensuring you can source the exact fastener your model requires without confusion or compatibility issues.
- 4mm Length — The 4mm length specification provides the precise depth needed for secure fastening in HOBAO suspension systems, drivetrain components and motor mounting applications, preventing overtightening while maintaining solid engagement.
- Genuine OEM Component — Manufactured by HOBAO, this is an authentic original equipment manufacturer part rather than a generic third-party alternative, guaranteeing material quality, threading precision and performance consistency across multiple installations.
- Essential Maintenance Spare — Set screws are subject to vibration, impact and regular loosening during RC car operation, making genuine replacement screws vital for maintaining structural integrity, preventing component failure and avoiding costly damage to your RC model.
- Universal RC Car Application — The M5x4 specification is used across numerous RC car platforms and upgrade applications, making this single part suitable for maintenance work on multiple vehicles in your RC collection.
Technical Performance
The HOBAO M5x4 Set Screw represents a precision-engineered fastening solution developed through HOBAO's extensive experience manufacturing high-performance RC vehicles and components. Set screws are purpose-designed fasteners that clamp onto the outer surface of shafts, pins and rods, creating positive mechanical locks without requiring a nut on the opposite side. This design makes them ideal for RC car applications where space is limited and tool access is restricted. The M5 metric specification indicates a 5mm major diameter, whilst the 4mm length provides adequate depth for secure engagement without creating excessive protrusion that could interfere with moving components or suspension geometry. HOBAO manufactures their fastening components using hardened steel materials that resist stripping, deformation and corrosion during regular RC car operation. The precise metric threading ensures compatibility with factory HOBAO parts and maintains the tight tolerances required for competition-grade RC vehicles. Whether you're replacing a damaged fastener following a crash during off-road RC driving, restoring a vintage HOBAO RC car, or performing preventative maintenance on a brushless RC buggy or truck, this set screw delivers the reliable performance expected from an original HOBAO component. The robust construction and authentic manufacturing standards make this an essential item for any serious RC enthusiast's maintenance toolkit.
What's in the Box
Frequently Asked Questions
- What is a set screw and why do I need it for my RC car? — A set screw is a fastener designed to clamp onto the outer surface of a shaft, pin or rod to create a positive mechanical lock. In RC cars, set screws are used throughout the drivetrain, suspension and motor mounting systems to secure components and prevent them from rotating or sliding loose during high-speed operation, jumps and rough terrain driving. When these screws become loose or damaged, replacement with genuine HOBAO parts ensures your RC vehicle maintains the structural integrity required for safe, reliable performance.
- Is this compatible with all HOBAO RC vehicles? — The M5x4 specification is a standard metric fastener used across many HOBAO RC car models and platforms. However, compatibility depends on your specific vehicle and the application point. We recommend checking your HOBAO instruction manual or contacting our knowledgeable RC specialists at RC Model Shop to confirm this fastener is suitable for your particular model before ordering.
- Can I use a generic set screw instead of a genuine HOBAO part? — Whilst generic fasteners may appear identical, HOBAO components are manufactured to precise tolerances and hardness specifications that ensure reliable performance in high-vibration RC car environments. Generic alternatives may have inferior threading, softer steel that strips easily, or slightly different dimensions that create loose fits. For competition racing, serious bashing, and long-term reliability, genuine OEM components like this HOBAO M5x4 Set Screw are strongly recommended.
- How often should I replace set screws on my RC car? — Set screws on RC vehicles should be inspected regularly, particularly after crashes, high-impact jumps or rough off-road driving sessions. If a screw becomes loose, stripped, or visibly damaged, it should be replaced immediately to prevent component failure and potential safety issues during RC operation. Many serious RC enthusiasts replace fasteners preventatively during seasonal maintenance to avoid unexpected failures during races or driving events.
- What tools do I need to install this set screw? — Installation requires an appropriate hex key or Allen key matching the socket size of your set screw (the specific size will depend on your HOBAO component design). Standard RC tool kits typically include the hex keys required for set screw installation, and our RC Model Shop team can advise on the correct tool size if you are unsure.
