HoBao M3x18 Button Head Screw Black Hex Socket RC Fastener H33318

Overview

The HOBAO M3X18 Button Head Screw (H33318) is an essential replacement fastener for owners of HoBao RC vehicles. Whether you're maintaining your HOBAO Hyper MT Plus Electric Monster Truck, fine-tuning your HOBAO Hyper MT Sport Plus, or servicing your HOBAO Hyper VS2 1/8 Electric RTR Buggy, this precision-engineered screw is a critical component that keeps your RC car UK-legal and roadworthy. For serious RC enthusiasts and weekend bashers alike, having a stock of quality replacement fasteners is part of responsible RC car ownership and maintenance.

This M3x18mm button head screw features a machine thread design with a distinctive hex socket head, making it compatible with standard RC tool sets. The black finish not only looks professional but also resists corrosion, ensuring longevity even in challenging UK weather conditions. If you're experiencing stripped threads, lost fasteners, or simply need spare parts for your HoBao ready to run RC vehicle, this button head screw provides the reliability and precision fit you need to get back on the track or trail.

HoBao is renowned for engineering high-performance RC models that demand quality components, and this fastener meets those exact standards. As part of your ongoing RC maintenance toolkit, the H33318 represents the kind of small but vital detail that separates well-maintained machines from those prone to mechanical failure.

Key Features

• M3 Thread Size — This M3 specification means the screw has a 3mm diameter, which is a standard size across many HoBao vehicle platforms, making it a versatile addition to any RC enthusiast's spare parts collection.
• 18mm Length — The 18mm length is precisely engineered for specific mounting points across the HoBao Hyper MT and Hyper VS2 model range, ensuring proper seating and correct fastening depth without over-tightening.
• Button Head Design — The button head profile provides a larger contact surface compared to standard socket head caps, distributing clamping force across a wider area and reducing the risk of stripping soft aluminium components common in RC vehicles.
• Hex Socket Driver — The hex socket design means you can use standard RC tool hex keys for installation and removal, allowing for quick field adjustments and maintenance without requiring specialist equipment.
• Machine Thread Type — Machine threading (as opposed to self-tapping) ensures consistent thread engagement when used in pre-drilled holes, delivering reliable fastening performance that won't loosen under the vibration and impacts typical of RC driving.
• Black Finish — The black coloured coating provides visual consistency with other quality fasteners whilst offering protection against surface corrosion, particularly important when your RC car UK is exposed to wet terrain or stored for extended periods.

Technical Performance

The HOBAO M3X18 Button Head Screw represents precision engineering at the component level. HoBao's commitment to quality means this fastener is manufactured to exacting tolerances, ensuring proper thread fit within the mounting bosses of your RC vehicle without wobble or play. The machine thread design requires pre-drilled holes but delivers superior holding power compared to self-tapping alternatives, which is essential when mounting critical assemblies like suspension arms, chassis plates, and electronic components on your ready to run RC setup. The hex socket head accepts standard tool sizes, making field maintenance straightforward for both experienced builders and newcomers to the RC hobby. The button head profile, with its slightly domed cap, provides approximately 1.5 times more contact area than a standard socket head cap of the same size, significantly reducing the probability of stripping the receiving hole in lightweight aluminium chassis components—a common failure mode in RC vehicles subject to repeated assembly and disassembly cycles. The black finish is applied to resist oxidation and maintain the professional appearance of your vehicle's internal components, though the primary benefit is functional corrosion resistance that extends the lifespan of the fastener itself.

Frequently Asked Questions

• Which HoBao RC vehicles use the M3X18 button head screw? — This fastener is compatible with several HoBao models including the HBMT-EPLUS Hyper MT Plus Electric Monster Truck Rolling Chassis, the HBMTE-C150BU Hyper MT Sport Plus RTR with HW150a ESC and 18kg servo in blue, the HBMT-C30BU Hyper MT Sport Plus Nitro RTR with 18KG servos in blue, the HB-VS2E-C100Y Hyper VS2 1/8 Electric RTR Buggy with 4S 100A ESC, the HB-VS2E Hyper VS2e 1/8 Electric Roller Buggy, the HB-VS2E-C150Y Hyper VS2 1/8 Electric RTR Buggy with 6S 150A ESC, the HB-VS2-C21Y Hyper VS2 1/8 Nitro RTR Buggy with Hyper 21 engine, the HB-VS2 Hyper VS2 1/8 Nitro Roller Buggy, and the HB-VS2-C30Y Hyper VS2 1/8 Nitro RTR Buggy with Hyper 30 engine.
• Why would I need replacement button head screws for my RC car? — RC vehicles experience constant vibration, impacts, and stress during operation and handling. Fasteners can become lost during crashes, stripped through repeated assembly and disassembly, or corroded if exposed to moisture. Having replacement screws ensures you can quickly restore your RC car UK to full working order without waiting for parts delivery or having to source incorrect alternatives.
• What is the difference between button head and socket head cap screws? — Button head screws feature a domed cap that extends further above the surrounding surface, providing greater contact area and reduced risk of stripping softer materials like aluminium. Socket head cap screws have a cylindrical head that sits flush with the surrounding surface. For RC applications where fasteners may be repeatedly installed and removed, the button head design offers superior durability.
• Can I use any hex key tool with this screw? — The hex socket design accepts standard hex key tools of the appropriate size, making this screw compatible with any quality hex driver set. However, always use a well-fitting tool to avoid stripping the socket—loose-fitting tools are the primary cause of hex socket damage.
• Is this screw suitable for beginners? — Yes, absolutely. Beginners can use this fastener when performing basic maintenance on HoBao vehicles. The hex socket design makes installation straightforward, though care should be taken to avoid over-tightening, which can strip the receiving hole or crack plastic components. Always tighten to firm contact without forcing.
