Overview
The ARRMA Flat Head Hex Machine Screw 4x15mm 4x4 (4) Z-AR722415 is an essential replacement part for any serious RC enthusiast in the UK who owns an ARRMA vehicle. Whether you're maintaining a 1/10 scale monster truck, stadium truck, short course truck, or 1/8 scale buggy, these precision-engineered fasteners are designed to keep your RC car UK-ready and operating at peak performance. As a dedicated RC hobbyist, you understand that quality hardware is just as important as the major drivetrain components—these screws deliver the reliability and durability that ARRMA vehicles demand.
ARRMA has engineered these flat head hex machine screws to be the perfect servicing solution for their extensive range of RTR ready-to-run RC vehicles. From the Big Rock and Granite monster trucks to the Kraton and Outcast speed trucks, Senton short course trucks, Vorteks stadium trucks, through to the 1/8 scale Infraction street bash, Mojave desert truck, Typhon buggy, and Vendetta all-road models, these screws are specified as standard parts across the entire ARRMA lineup. The countersunk flat head design allows for flush mounting, creating a professional finish whilst maintaining structural integrity during aggressive driving or racing conditions.
When you're out bashing with friends, competing at your local RC track, or simply maintaining your vehicle collection, having a reliable supply of genuine ARRMA spare parts ensures you can keep racing without delay. These screws come bagged in convenient multiples so you always have spares on hand for routine maintenance, repairs, or upgrades to your brushless RC monster truck, 4WD speed truck, short course truck, stadium truck, or buggy.
Key Features
- M4 x 15mm Specification — These machine screws are precisely sized at M4 diameter with 15mm length, providing the exact fitment required across the entire ARRMA vehicle range. This standardised sizing ensures hassle-free replacement without compatibility issues.
- Flat Head Countersunk Design — The countersunk flat head allows these screws to sit flush with the mounting surface, creating a smooth aerodynamic profile and preventing snagging during high-speed driving or off-road bashings.
- Hex Machine Thread — The precision-manufactured machine threads provide fast and easy maintenance, allowing you to quickly service your RC vehicle without damaging the thread or requiring excessive torque. The machine thread design guarantees consistent fastening every time you need to access components.
- Strong Steel Material — Manufactured from high-quality steel, these screws deliver long-lasting durability that withstands the rigours of RC driving, from lightweight stadium truck racing to aggressive monster truck bashing and technical buggy courses.
- Hex Driver Type — The hex socket head design ensures positive engagement with your hex key or wrench, preventing slipping and rounding of the screw head during installation or removal, which is essential for maintaining component integrity.
- Pack of Four — Each pack contains four screws, allowing you to complete common maintenance tasks or have reliable spares ready for future repairs and upgrades to your RC car collection.
- Black Colour Finish — The black finish matches standard ARRMA hardware, maintaining a professional appearance on your 4WD brushless RC monster truck, short course truck, stadium truck, buggy, or desert truck.
- Genuine ARRMA Product — As original equipment manufacturer parts, these screws are engineered and tested to ARRMA's exacting standards, ensuring compatibility and performance across their entire vehicle lineup from beginner-friendly RTR models through to competition-grade racing vehicles.
Technical Performance
These M4 x 15mm flat head hex machine screws represent the precision engineering that separates quality RC hardware from inferior aftermarket alternatives. Manufactured from strong steel with precision-engineered threads, they deliver consistent performance across the full spectrum of ARRMA vehicles, whether you're running a 1/10 scale brushless monster truck, a lightweight 1/10 short course truck, a nimble 1/10 stadium truck, a high-speed 1/10 speed truck, or an advanced 1/8 scale brushless buggy or desert truck. The countersunk flat head design is critical for vehicles that demand aerodynamic efficiency and component protection, as it prevents the screw head from protruding and potentially causing air turbulence or snagging on rough terrain. The hex socket engagement ensures you can apply precise torque without risk of damaging the screw head, which is essential when working on delicate composite or aluminium components. Whether you're performing routine maintenance on your RTR ready-to-run vehicle, replacing worn fasteners after a season of competitive racing, or building up spare parts inventory, these screws provide the reliability and durability you expect from genuine ARRMA original parts.

Frequently Asked Questions
- Which ARRMA vehicles use these M4 x 15mm flat head hex screws? — These screws are specified as standard parts across the entire ARRMA 1/10 and 1/8 scale range. For 1/10 scale, they're used in the Big Rock monster trucks (223S and 3S models), Granite monster trucks including the brushless and brushed variants and the Granite Boost, Kraton 4S speed trucks, Outcast 4S stunt trucks, Senton short course trucks including the Boost variant, and Vorteks stadium trucks including the Boost variant. For 1/8 scale, they're fitted to the Infraction street bash trucks, Mojave desert truck, Typhon buggies, and Vendetta all-road models. Whether you own a brushless RTR model or a brushed variant, these screws deliver compatible fastening solutions.
- Are these genuine ARRMA parts or aftermarket replacements? — These are genuine ARRMA original equipment manufacturer parts, manufactured to their specifications and tested for quality and compatibility. Choosing genuine parts ensures perfect fitment, reliable performance, and maintains the integrity of your investment in a quality RC vehicle.
- How many screws come in this pack, and how often will I need replacements? — Each pack contains four flat head screws. Most routine maintenance tasks may only require one or two screws, so keeping a pack or two in your RC toolkit ensures you're never caught without spares. Serious racers and frequent bashers typically keep multiple packs on hand for component rebuilds and seasonal maintenance.
- What is the purpose of the countersunk flat head design? — The countersunk flat head allows the screw to sit flush with the mounting surface rather than protruding outward. This is critical for RC vehicles because it maintains aerodynamic efficiency, prevents the screw head from snagging on obstacles during off-road driving, and creates a professional finished appearance on your brushless RC monster truck, buggy, or short course truck.
- Can I use these screws to repair other RC vehicles or only ARRMA models? — Whilst the M4 x 15mm specification is universal, these screws are engineered and tested specifically for ARRMA vehicles. If you own other brands like Traxxas, Losi, or FTX, we recommend using parts specified for those vehicles to ensure proper fitment and performance. However, the universal M4 x 15mm spec means they may be compatible with other applications requiring identical specifications.
- What tools do I need to install or remove these screws? — The hex socket head requires only a hex key or hex wrench of the appropriate size—typically supplied with your ARRMA vehicle or available as an accessory. The hex drive design ensures positive engagement, minimising the risk of slipping or rounding the socket.
