These grub screws are essential spare parts for maintaining and repairing your RC vehicle, ensuring that critical connection points remain secure during high-performance driving sessions.

HoBao is a recognised manufacturer of high-quality RC cars and components, delivering products that meet the exacting standards of RC enthusiasts worldwide. The M3X3 set screws represent the kind of attention to detail and quality that defines HoBao's approach to RC engineering. These fasteners are manufactured to precise specifications, ensuring perfect fitment and reliability across a range of HoBao Hyper models and specialist RC vehicles.

When you choose ready to run RC cars or build your own kit, the importance of quality fasteners cannot be overstated. Set screws like these are the unsung heroes of RC maintenance, holding together suspension arms, drive components, and chassis elements that experience constant stress during operation. The HoBao M3X3 set screws deliver the dependability you need to keep your RC car running smoothly, whether you're preparing for a race or enjoying casual outdoor driving sessions.

Key Features

• Machine Thread Construction — These set screws feature a machine thread design that provides consistent, reliable engagement with tapped holes in your RC car components, ensuring a secure and permanent connection that won't loosen during intense driving conditions.
• Hexagonal Driver Type — The hex socket head design allows for precise, controlled tightening with standard hex key tools, giving you the mechanical advantage needed to achieve proper fastening torque without risk of stripping the fastener or damaging surrounding components.
• Grub Head Style — The grub head configuration sits flush or nearly flush with the surface once installed, creating a clean aesthetic appearance whilst providing excellent holding power for small-diameter connection points throughout your RC vehicle.
• 3mm Length Specification — At 3mm in length, these screws are precisely sized to suit the compact dimensions of modern RC car components, including chassis plates, suspension arms, and drivetrain elements on HoBao Hyper models.
• M3 Metric Size — The M3 metric specification ensures compatibility with standard RC car tapped holes and fastening points, making these screws a reliable solution for maintenance and repair work on multiple HoBao models.
• 10-Piece Pack — This generous pack of 10 individual screws provides multiple spares, ensuring you always have replacements available when fasteners require replacement due to wear, loss, or damage during aggressive driving sessions.
• Genuine HoBao Component — These are authentic HoBao parts manufactured to original equipment specifications, guaranteeing perfect compatibility and the same quality standards that define HoBao RC vehicles.

Technical Performance

The HoBao M3X3 set screws are engineered from high-quality material designed to withstand the operational stresses of competitive and recreational RC driving. The machine thread construction creates a secure mechanical bond that resists vibration loosening, a critical factor in RC vehicles where constant acceleration, deceleration, and cornering forces can work fasteners loose over time. The hexagonal socket head provides a substantial contact patch, distributing tightening force across the fastener head and reducing the likelihood of stripping or cam-out. The 3mm length is precisely calculated to suit HoBao's compact chassis and suspension geometry, ensuring these screws engage properly with tapped holes without protruding excessively or sitting too shallow. Build quality is paramount in RC fasteners, as a single failed screw can cascade into component failure, suspension misalignment, or drivetrain damage. HoBao's commitment to manufacturing excellence means these set screws meet the demanding requirements of modern RC engineering, whether you're running an off-road buggy, short course truck, or on-road racing vehicle. The grub head design minimises external protrusions, protecting the screw from impact damage during crashes or rough handling whilst maintaining a professional appearance in your build.

Frequently Asked Questions

• Which HoBao RC models are compatible with the M3X3 set screws? — These M3X3 set screws are compatible with a wide range of HoBao Hyper models, including the HB-SC2E Hyper 10SC 2.0 Electric Short Course Truck (available in multiple colour variants including Clear, Blue, Grey, Orange/Black, and Blue/White bodies), the HBSS Hyper SS 1/8 Buggy (both Mach 28 and Hyper 21 engine versions), and the HB-VS2E and HB-VS2 Hyper VS2 1/8 Buggies in both electric and nitro configurations. These fasteners are engineered to suit the precise specifications of HoBao's chassis and component design across multiple model lines.
• Are these genuine HoBao parts? — Yes, the H38303 model number confirms these are authentic HoBao manufactured components. When you purchase HoBao set screws, you're investing in genuine parts that meet original equipment specifications, ensuring perfect fitment and reliability with your RC model.
• Why would I need replacement set screws for my RC car? — Set screws can loosen or require replacement for several reasons during regular RC car operation. Vibration from engine or motor operation can work fasteners loose over time, crashes can cause screws to bend or damage the surrounding component material, and normal wear can reduce fastening strength. Having a pack of 10 replacement screws ensures you can address these issues quickly without interrupting your driving sessions or competitions.
• What tools do I need to install these set screws? — The hexagonal socket head design means you'll need a hex key or hex wrench that matches the socket size. Most RC enthusiasts already have a set of metric hex keys in their maintenance toolkit, making installation straightforward and accessible even for beginners learning RC car maintenance and repair.
• Can these screws be used on other RC car brands? — Whilst these screws are specifically engineered for HoBao models, the M3 metric specification is a standard size used across the RC hobby. If you have other RC cars with M3 tapped holes requiring 3mm screws, these could potentially be compatible, though HoBao recommends using these for their intended purpose to ensure optimal performance and compatibility.
• How often should I check my RC car's set screws? — Good maintenance practice suggests checking all visible set screws and fasteners before each driving session, particularly after crashes or high-impact events. If you notice any screw is loose, missing, or stripped, replace it immediately with one of your spare M3X3 set screws to prevent further component damage.
