Overview
The ARRMA Set Screw M3x4mm (10) Z-ARA724304 is an essential spare parts item for anyone who owns an ARRMA RC vehicle. Whether you're running an ARRMA 1/16 scale monster truck, rock crawler, or desert buggy, these precision-manufactured set screws are crucial for ongoing maintenance and repairs. Set screws are small but vital fasteners used throughout RC car chassis, suspension components, motor assemblies, and many other critical areas where secure fastening is essential. Having a supply of quality replacement set screws on hand means you can quickly service your RC car without delay, keeping your model running at peak performance whether you're bashing in the garden, competing at your local RC club, or taking on challenging terrain.
These high-quality set screws are the perfect items for servicing your ARRMA vehicle and represent genuine manufacturer parts that ensure compatibility and reliability. ARRMA is renowned for producing durable, high-performance RC vehicles across multiple scales, from the popular 1/16 GROM range to larger competition-grade models. Using genuine ARRMA spare parts like these set screws means you're maintaining your investment with components engineered specifically for your vehicle, ensuring consistent performance and longevity. UK RC enthusiasts trust ARRMA products for their quality and value, and these set screws uphold that reputation perfectly.
Whether you're a seasoned RC racer, a weekend basher, or someone new to the hobby, keeping spare fasteners in your toolbox is essential maintenance practice. These M3x4mm set screws come bagged in convenient multiples, so you always have spares available when you need them most.
Key Features
- Strong steel material — Manufactured from robust steel that provides long-lasting durability and ensures consistent fit every time you use them, preventing loosening during driving and maintaining secure fastening under the vibrations and stresses of RC vehicle operation.
- Precision manufactured threads — The threads on these set screws are precision-engineered to ISO standards, allowing for fast and easy maintenance without stripping or cross-threading, which saves time during servicing and means the screws will work reliably across multiple installation cycles.
- Bagged in multiples — These screws are conveniently packaged in quantities of 10, providing a ready supply of spares so you always have replacements available without needing to order more frequently or buy larger bulk quantities than you need.
- Black finish — The black colour provides both aesthetic consistency with most ARRMA vehicle designs and practical identification when sorting through your spare parts collection.
- Grub head design — The grub screw (also called a cup point or set screw) head type is ideal for securing components where a flush or hidden fastening point is preferred, particularly in suspension components and motor assemblies where protruding screw heads could interfere with movement or performance.
- Hex driver type — The hexagonal socket design accepts standard hex Allen keys or drivers, which are universal tools found in most RC tool kits and maintenance boxes, making installation and removal straightforward for any RC enthusiast.
- Genuine ARRMA parts — As authentic manufacturer components, these set screws are engineered specifically for ARRMA vehicles and carry the quality assurance of the brand, ensuring perfect compatibility and reliable performance.
Technical Performance
The M3x4mm specification refers to the ISO metric thread size: M3 denotes a 3mm diameter shaft with metric threading, whilst the 4mm measurement indicates the overall length of the screw. This size is commonly used throughout 1/16 scale ARRMA vehicles and many other small-scale RC cars for fastening suspension components, motor mounts, drive shafts, servo brackets, and chassis assemblies. The precision-manufactured threads ensure smooth insertion into pre-threaded holes and consistent holding power. The steel construction provides excellent strength-to-weight ratio, essential in RC vehicles where every gram counts towards performance. The grub screw design means these fasteners sit flush when installed, preventing interference with moving parts and maintaining the aerodynamic profile of your RC car. The hex socket driver type is industry standard across RC maintenance tools, meaning you won't need any specialist equipment beyond a basic metric hex key set. These screws perform reliably across repeated disassembly and reassembly cycles, which is essential during regular maintenance, upgrades, and repairs. Whether you're securing a motor pinion, tightening suspension geometry, or fastening servo linkages, these set screws provide the holding power and reliability that ARRMA vehicles demand.

Frequently Asked Questions
- What size are ARRMA set screws and why does the size matter? — The M3x4mm designation indicates a 3mm diameter thread with 4mm overall length, conforming to ISO metric standards. Size matters because using the correct screw size ensures proper fit in pre-drilled holes, prevents cross-threading, and provides the appropriate holding strength without over-tightening and stripping the threads or under-tightening and causing loosening during driving.
- How many set screws come in this pack? — This pack contains 10 M3x4mm set screws, providing a generous supply of spares for multiple servicing sessions or emergency repairs. Most RC enthusiasts find that keeping 10 spare screws of each common size ensures they won't run out during the season.
- Are these set screws suitable for beginners? — Yes, absolutely. These set screws are essential spares for RC owners of all experience levels. Beginners will find them easy to install using a basic hex key, and having spares available means you can learn maintenance without worrying about running out of fasteners. The straightforward hex socket design requires no specialist tools beyond what's in any basic RC maintenance kit.
- What vehicles are these compatible with? — These M3x4mm set screws are compatible with ARRMA 1/16 scale vehicles including the GORGON GROM, Mini Kraton 3S, MOJAVE GROM, and QUAKE GROM models in all colour variants. They may also be compatible with other ARRMA vehicles and RC cars from other brands that use M3x4mm fasteners in their assemblies, but ARRMA vehicles are the primary intended application.
- Why should I buy genuine ARRMA spares rather than generic set screws? — Genuine ARRMA set screws are engineered specifically for ARRMA vehicles, ensuring perfect compatibility, consistent quality, and reliable performance. They're manufactured to the same specifications and standards as the fasteners originally supplied with your vehicle, meaning they'll provide identical holding power and longevity. Using genuine parts also ensures you're maintaining your warranty and keeping your investment in good condition.
- How often should I replace set screws on my RC car? — Set screws typically last indefinitely if properly installed and maintained. However, replace them if you notice threads becoming stripped, if screws consistently come loose despite proper tightening, or if you accidentally damage them during installation or removal. It's good practice to inspect all fasteners during regular maintenance and replace any showing wear. Many RC enthusiasts replace the complete set of fasteners as preventative maintenance once per season.
- Do I need any special tools to install these set screws? — No special tools are required beyond a metric hex key (Allen key) of the appropriate size, which should match the socket size of these grub screws. Most RC maintenance kits include hex key sets covering all common sizes, so you likely already have the necessary tool.
