Overview
The ARRMA Double Socket Button Head Screw 4x10mm (8) Z-AR727410 is an essential replacement hardware component for owners of ARRMA RC models. These precision-engineered screws are specifically designed to maintain the integrity and performance of your RC car UK setup, whether you own a high-performance monster truck, stunt truck, or other ARRMA vehicle. As a dedicated RC enthusiast, you understand that quality hardware is fundamental to reliable performance, longevity and safety on the track or bash course.
This pack contains eight individual double socket button head screws, each measuring M4 x 10mm with a machine thread specification. The button head design combined with hex socket driver compatibility makes these screws ideal for applications where you need secure fastening with easy adjustment and removal using standard hex keys. Whether you're performing routine maintenance on your brushless RC monster truck, upgrading components, or replacing worn fasteners, these ARRMA-branded screws ensure you're using genuine OEM-standard parts that maintain factory specifications.
ARRMA has engineered these screws to work seamlessly across their range of RC vehicles, from the powerful Kraton 4X4 4S V2 BLX Speed Monster Truck to the massive Outcast 8S stunt truck platform. Many experienced RC enthusiasts use these screws to enhance their setup—for example, replacing factory droop grub screws with the button head configuration to prevent chassis damage during aggressive bashing and racing.
Key Features
- Double Socket Design — The double socket head allows for reliable engagement with hex keys, preventing stripping and ensuring consistent torque application every time you service your RC car UK model, which is critical when working on precision-engineered vehicles where loose fasteners can cause performance issues.
- M4 x 10mm Specification — This size is engineered specifically for ARRMA platforms, providing the correct thread pitch and length for proper fitment without binding or coming loose during high-speed runs and aggressive driving conditions.
- Button Head Profile — The compact button head design minimises profile and allows screws to sit flush against components, reducing snagging and interference with suspension, chassis parts and moving elements on your RC vehicle.
- Machine Thread Construction — Precision machine threading ensures consistent engagement and prevents cross-threading, which is essential for maintaining accuracy across multiple assembly and disassembly cycles during a season of RC competition or casual bashing.
- Pack of Eight — You receive eight screws per pack, giving you sufficient hardware for multiple repair jobs, component upgrades, or building spare assemblies for competition or weekend bash sessions.
- Black Finish — The black colour finish matches ARRMA's standard hardware aesthetic and provides subtle corrosion resistance, maintaining appearance across multiple servicing cycles and outdoor use.
- Genuine ARRMA Component — These are authentic manufacturer parts, not generic alternatives, ensuring perfect fit and performance compatibility with your ARRMA RC monster truck, stunt truck or other compatible models.
Technical Performance
The ARRMA Double Socket Button Head Screw 4x10mm represents precision engineering in RC hardware. The M4 machine thread specification provides a standard metric pitch that ensures repeatable fastening torque without risk of over-tightening or cross-threading. The 10mm length is specifically calibrated for ARRMA chassis applications, particularly on suspension droop adjustment points, mounting brackets and body retention systems where precise spacing is critical to maintaining optimal ride height and handling geometry. The double socket head design permits use with standard 3mm hex keys, allowing RC enthusiasts to apply consistent torque without tool slipping or head stripping—a common problem with cheaper generic fasteners that use shallow socket geometry. The black finish provides corrosion resistance suitable for both indoor track use and outdoor bashing conditions, maintaining appearance and function across extended periods of use. These screws have been proven across multiple ARRMA platforms including the Kraton 4X4 4S V2 BLX Speed Monster Truck, Outcast 4X4 8S BLX EXB brushless stunt truck, and various other ARRMA models, demonstrating reliable performance and dimensional accuracy that experienced RC builders and competitors depend upon for consistent setup and performance.

Frequently Asked Questions
- Are these ARRMA screws compatible with my RC model? — These M4 x 10mm double socket button head screws are confirmed compatible with multiple ARRMA models including the Kraton 4X4 4S V2 BLX Speed Monster Truck, Outcast 4X4 8S BLX EXB Brushless Stunt Truck RTR, and other ARRMA platforms. Check your vehicle documentation or contact us to confirm compatibility with your specific model before ordering.
- What tool do I need to install these screws? — These double socket button head screws require a 3mm hex key (Allen key) for installation and adjustment. This is a standard tool found in most RC tool kits, making these screws simple to work with for routine maintenance and repairs.
- How many screws do I get in this pack? — This pack contains eight individual M4 x 10mm screws, providing sufficient hardware for multiple repairs, component upgrades, or building spare suspension and chassis assemblies for your brushless RC monster truck or stunt truck platform.
- Can I use these as replacements for factory grub screws? — Yes—many experienced RC enthusiasts use these button head screws as direct replacements for factory droop adjustment grub screws. The button head design sits lower against the chassis and helps prevent the chassis from digging into terrain during aggressive bashing, improving durability and protecting your investment.
- What is the difference between double socket and single socket screws? — Double socket button head screws have deeper hex socket engagement on both sides of the head, providing superior grip and preventing stripping compared to single socket designs. This makes them more reliable for repeated assembly and disassembly during regular RC vehicle maintenance and tuning.
- Are these genuine ARRMA parts? — Yes, these are authentic ARRMA manufacturer parts confirmed by the official ARRMA Z-AR727410 model number. Using genuine OEM parts ensures perfect fitment, dimensional accuracy and performance compatibility across your RC car UK setup.
