HoBao M3 X 4 Button Head Screw RC Spare Part H33304

Overview

The HOBAO M3 X 4 Button Head Screw H33304 is a precision fastening component designed for RC hobbyists and serious racers who demand reliable, high-quality spare parts for their remote control vehicles. Whether you're maintaining a 1/10 scale RC buggy, monster truck, or any other RC car UK enthusiast might own, having the correct replacement screws on hand is essential for keeping your model in peak running condition. This M3 button head screw represents genuine OEM (original equipment manufacturer) quality from HoBao, a respected name in RC racing and hobby engineering.

Button head screws are favoured in RC applications because their low-profile, rounded head design sits flush with components, reducing aerodynamic drag and preventing snags during high-speed running or competitive racing. The M3 X 4 specification means this screw has a 3mm diameter with a 4mm length, making it suitable for securing lightweight components on mid-scale RC platforms. For anyone building, upgrading, or maintaining an RC car UK-based, having genuine replacement fasteners ensures compatibility and longevity.

Sourced directly from HoBao's manufacturing network, this button head screw is engineered to exacting tolerances, ensuring perfect fit and reliable retention even under the vibration and stress of extended bashing or track racing. RC model shops across the UK recognise the importance of stocking OEM-equivalent fasteners, and this part represents the kind of attention to detail that separates serious hobbyists from casual users.

Key Features

• M3 X 4 Dimension Specification — The M3 diameter and 4mm length make this screw ideal for securing internal and external components on mid-scale RC vehicles, ensuring proper fitment without over-tightening or stripping.
• Button Head Design — The rounded, low-profile button head sits flush against mounting surfaces, reducing unnecessary protrusions that could catch on terrain during RC driving or impact during crashes and collisions.
• Genuine HoBao Manufacturing — As an authentic HoBao OEM part, this screw is manufactured to the same specifications and quality standards as screws supplied with new HoBao RC kits, guaranteeing compatibility with HoBao vehicle platforms.
• Precision Threading — The screw features accurately cut threads that grip firmly without cross-threading, essential when working with soft-metal inserts or plastic housings common in RC chassis and body components.
• Lightweight Material Construction — Designed with weight savings in mind, typical of RC engineering principles, this fastener contributes minimal mass while maintaining structural integrity under driving loads.

Technical Performance

The HOBAO M3 X 4 Button Head Screw represents a critical component in RC vehicle assembly and maintenance. In the demanding environment of RC racing and bashing, fasteners experience constant vibration, impacts, and lateral stress as vehicles navigate tracks, terrain, and jumps. The M3 diameter provides sufficient holding capacity for lightweight components whilst remaining small enough for precision RC applications where space is limited. The 4mm length is engineered to penetrate through typical component thicknesses—such as aluminium chassis plates, plastic body panels, and carbon-fibre brackets—without bottoming out or protruding excessively. The button head design, distinct from traditional hex socket or slotted heads, offers several engineering advantages: it reduces catching points during high-speed running, maintains structural aesthetics on visible components, and allows for tighter packing density in assembled RC models. For builders maintaining ready-to-run RC vehicles or restoring older RC cars UK collectors might own, having authentic replacement screws prevents the frustration of stripped threads or incompatible fasteners that compromise vehicle performance and handling characteristics.

Frequently Asked Questions

• What is the M3 X 4 specification and why does it matter for my RC vehicle? — The M3 X 4 designation indicates a 3 millimetre diameter screw with 4 millimetre length. This size is standard for securing lightweight components on 1/10 and 1/8 scale RC buggies, trucks, and bashers. Getting the correct size ensures your RC car stays assembled properly without loose components affecting handling or causing crashes.
• Is this screw compatible with all HoBao RC models? — This is a genuine HoBao OEM part designed for HoBao vehicles that specify M3 X 4 fasteners in their assembly manuals. Before purchasing, check your vehicle's manual to confirm M3 button head screws are the correct replacement for your application, as different HoBao models may use various fastener sizes.
• Can I use this screw to replace a damaged fastener on my RC car? — Yes, this genuine HoBao part is specifically designed as a replacement fastener for HoBao RC vehicles. If you have a missing or stripped M3 X 4 button head screw, this part will restore proper component retention and prevent further damage or loss of parts during driving.
• Why choose genuine HoBao fasteners instead of generic hardware store screws? — Genuine OEM screws like this HoBao part are manufactured to precise tolerances matching your vehicle's threaded inserts and component thicknesses. Generic screws may have slightly different dimensions, coarser threading, or softer materials that strip easily under the vibration and stress of RC driving, leading to component failure and potential crashes.
• What should I do if I repeatedly lose this screw during running? — If M3 X 4 button head screws keep loosening during use, the threaded insert in your RC vehicle may be worn or damaged. Consider using a thread-locking compound (medium strength, removable type) on the screw threads to prevent vibration-induced loosening. Ensure you're not over-tightening, which can strip the insert.
