Overview

The FTX Button Head Hex Screw M4 X 12mm (FTX9650) is an essential fastening component for RC enthusiasts maintaining and upgrading their FTX RC cars and trucks. Whether you're a dedicated RC car UK hobbyist working on repairs, customisation, or routine maintenance, these precision-engineered screws are the genuine OEM parts you need to keep your vehicle running at its best. FTX is renowned for producing high-quality RC vehicles across a diverse range of scales and styles, and their spare parts are manufactured to the same exacting standards that make their ready to run RC cars so popular amongst UK RC enthusiasts.

This pack contains eight individual button head hex screws, each precisely machined to M4 x 12mm specifications. Button head screws are favoured in RC applications because their low-profile, rounded head design minimises the risk of catching on other components during assembly, and they provide a clean, professional appearance on finished builds. The hex drive system ensures you can apply consistent torque without risk of stripping, making these screws ideal for both precision assembly work and field repairs at the track or bash spot. If you're building an FTX DR8 1/8 Desert Racer or maintaining any other FTX RC model, having spare fasteners on hand is essential for keeping your hobby on track.

Key Features

• M4 x 12mm Specification — The precise M4 metric thread diameter combined with 12mm length makes these screws compatible with a wide range of FTX RC vehicle models, ensuring you have the correct fastening solution for your specific RC car or truck assembly.
• Button Head Design — The low-profile, rounded button head is specifically engineered for RC applications, minimising protrusion and reducing the risk of snagging during assembly or catching on chassis components during operation, resulting in a clean professional finish on your RC build.
• Hex Drive Socket — The recessed hex socket allows you to apply even, consistent torque using a hex key driver without risk of stripping or damaging the screw head, which is essential when working with precision RC components where overtightening can cause damage.
• Machine Thread Construction — These are machine thread screws designed for use with threaded inserts or pre-tapped holes, providing secure, repeatable fastening that won't work loose during the vibration and impacts experienced by off-road RC vehicles during aggressive driving.
• Black Finish — The black coating provides durability and a professional appearance, whilst the finish helps protect against corrosion when your RC car is exposed to moisture during outdoor bashing sessions.
• Pack of Eight — Receiving eight screws in a single pack means you have extras for replacement parts, future builds, or backup fasteners, which is particularly valuable when you need multiple identical fasteners for a specific RC vehicle assembly.
• Genuine FTX OEM Parts — These are authentic factory parts specified for FTX vehicles, guaranteeing compatibility and quality standards that match the exacting requirements of FTX's own manufacturing process.

Technical Performance

These button head hex screws represent the fastening solution FTX engineers chose for their production RC vehicles, which tells you everything about their suitability for precision RC applications. The M4 metric specification delivers the ideal balance between holding power and weight for scale RC vehicles, whilst the 12mm length has been calculated to work across multiple FTX model platforms without interfering with moving components or suspension geometry. The machine thread design means these screws work with FTX's pre-tapped aluminium and composite chassis components, creating a secure, vibration-resistant fastening point that won't migrate or loosen under the extreme acceleration, deceleration and cornering forces experienced by modern RC cars and trucks. The button head profile eliminates the problem of standard socket head cap screws catching on suspension arms or getting damaged during crash events. The hex drive system provides superior grip compared to Phillips or slot drives, meaning you can apply proper torque without the screwdriver slipping and stripping the drive socket. For RC enthusiasts in the UK maintaining their own vehicles or building from kits, having a supply of these genuine spare fasteners ensures every rebuild or repair uses the correct specification, maintaining structural integrity and component compatibility across your entire FTX RC fleet.

Frequently Asked Questions

• What FTX RC cars and trucks use these M4 x 12mm button head hex screws? — The FTX9650 screws are specified as compatible spare parts for the FTX DR8 1/8 Desert Racer 6S RTR in both Blue and Red variants. However, as these are standard metric fastening components, they may also be compatible with other FTX RC vehicle models that use M4 threaded holes. Check your specific vehicle's parts diagram or contact RC Model Shop if you need confirmation for your particular model.
• Why are button head hex screws preferred for RC vehicles compared to other fastener types? — Button head screws feature a low-profile, rounded head design that minimises protrusion from the chassis, reducing the risk of snagging on suspension components, terrain during bashing, or other parts during crashes. The recessed hex socket also provides superior grip compared to Phillips or slot drives, allowing proper torque application without slipping and stripping the drive socket, which is crucial when working with precision RC components. Additionally, the button head profile gives RC builds a more professional, finished appearance.
• How many screws do I get in this pack? — This pack contains eight individual FTX Button Head Hex Screws M4 x 12mm, providing you with multiple fasteners for replacement parts, future projects, or backup spares to keep in your RC maintenance kit for trackside repairs.
• What is the difference between machine thread and self-tapping screws for RC use? — Machine thread screws like the FTX9650 are designed to work with pre-tapped threaded holes or threaded inserts, providing a precise, repeatable fastening point that won't wear out the hole after repeated assembly and disassembly cycles. Self-tapping screws cut their own threads and are better suited for use with composite materials where creating a dedicated threaded hole isn't practical. FTX vehicles use machine thread fasteners with precision-tapped aluminium and composite chassis components, ensuring you maintain the exact specifications the vehicle was engineered with.
• Can I use these screws as a replacement for damaged fasteners on my FTX RC vehicle? — Yes, the FTX Button Head Hex Screw M4 x 12mm is specified as a genuine spare part for FTX vehicles. If you've stripped a fastener hole or lost a screw during bashing, these are the correct replacement parts to restore your RC car to factory specification. Always ensure the receiving hole is properly threaded or fitted with an insert before installation to maintain secure fastening.
• What tools do I need to install these screws? — You'll need a metric hex key (Allen key) that fits the M4 hex socket. These are standard tools found in most RC maintenance kits. Avoid using oversized or undersized hex keys, as this can damage the socket. Apply steady, even pressure when tightening to secure the fastener without stripping the socket or overtightening, which can damage the chassis material.
