Overview
The ARRMA Flat Head Screw 3x20mm is an essential maintenance and repair component for owners of ARRMA RC vehicles across the UK. These high-quality fasteners are manufactured to OEM specifications and come in a convenient pack of 10 screws, ensuring you always have spare parts on hand when servicing your brushless RC car, truck, buggy or monster truck. Whether you're performing routine maintenance on your ready to run RC vehicle or undertaking more comprehensive repairs, these precision-engineered screws are the perfect replacement parts to keep your ARRMA model running at peak performance.
If you own any ARRMA RC vehicle—from the compact 1/10 scale models right through to the impressive 1/8 and 1/7 scale brushless machines—you'll find these flat head screws an invaluable addition to your spares box. ARRMA vehicles are renowned for their durability and performance, but like all RC cars, they require regular maintenance and occasional parts replacement. These M3x20mm screws are specifically designed for ARRMA fitment and are compatible with a vast range of ARRMA models including the Kraton, Outcast, Mojave, Infraction, Felony, Limitless, Typhon, Talion, Notorious and many more.
Every RC enthusiast knows the frustration of losing or stripping a screw during maintenance—these packs solve that problem by providing multiple spares at an affordable price. The precision manufacturing and super-strong steel construction mean these screws will provide consistent, reliable fastening across countless maintenance cycles, making them a smart investment for any serious RC hobbyist in the UK.
Key Features
- Super-Strong Steel Material — Manufactured from high-quality steel, these flat head screws offer exceptional durability and long-lasting performance, resisting corrosion and maintaining their integrity through repeated assembly and disassembly cycles during maintenance.
- Precision Manufactured Threads — The precisely cut threads ensure fast and easy maintenance, allowing you to quickly service your ARRMA RC vehicle without struggling with loose or poorly fitting fasteners that could slip or strip.
- Flat Head Countersunk Design — The countersunk head profile sits flush with component surfaces, providing a clean, professional finish and ensuring the screw doesn't protrude or catch on other parts, which is critical in high-vibration RC applications.
- M3x20mm Specification — The M3 diameter and 20mm length make these screws compatible with numerous ARRMA models and common assembly points throughout their chassis, body mounts and internal components.
- Hex Driver Type — These screws accept standard hex drivers (Allen keys), which are commonly available and provide a secure grip that minimises the risk of stripping the screw head during installation or removal.
- Bagged in Multiples — The pack contains 10 individual screws, giving you multiple spares to keep in your maintenance kit so you're never caught short during repairs or upgrades to your RC car or truck.
Technical Performance
These M3x20mm flat head screws represent the level of component quality you'd expect from an authorised ARRMA spare part. The super-strong steel construction provides the tensile strength needed to maintain secure fastening in the demanding environment of high-performance RC vehicles, which experience significant vibration and mechanical stress during operation. Whether you're running a 1/10 scale Kraton 4S, a 1/8 scale Notorious 6S, or a 1/7 scale Mojave 6S 4X4, these screws are engineered to the same specifications used in the original assembly. The precision-manufactured machine threads cut into the steel shaft ensure that when you're assembling your RC vehicle after maintenance, the screws engage smoothly and securely without the frustration of cross-threading or excessive force requirements. The countersunk flat head design is particularly important in RC applications, as it prevents fasteners from catching on suspension components, drive shafts, or other moving parts that could be damaged or cause vibration if a screw head protrudes. With a 3mm diameter and 20mm length, these screws address the most common fastening points throughout the ARRMA range, making them the ideal go-to spare for regular maintenance and component replacement. The black finish provides both aesthetic consistency with ARRMA's design language and enhanced corrosion resistance compared to bare steel alternatives.

Frequently Asked Questions
- What ARRMA models are compatible with these M3x20mm flat head screws? — These screws are compatible with an extensive range of ARRMA vehicles including the 1/10 Kraton 4S, 1/10 Outcast 4S, 1/5 Kraton 8S, 1/7 Big Rock 6S, 1/7 Felony 6S AVC, 1/7 Fireteam 6S, 1/7 Infraction 6S, 1/7 Infraction 6S AVC, 1/7 Limitless 120 8S AVC, 1/7 Limitless 6S, 1/7 Mojave 6S, 1/8 Infraction 223S DSC and 3S variants, 1/8 Kraton 6S in multiple versions, 1/8 Notorious 6S, 1/8 Outcast 6S including limited edition variants, 1/8 Talion 6S, 1/8 Typhon 6S and TLR Tuned variants, and 1/8 Vendetta 3S. Check your specific model's parts list to confirm fitment.
- Why should I buy spare screws if my ARRMA came with original fasteners? — During regular maintenance and repairs of your RC vehicle, screws can become stripped, lost, or damaged. Having a pack of spares means you're never stuck waiting for replacement parts to arrive, allowing you to complete repairs immediately and get back to running your brushless RC truck or buggy. These packs are inexpensive insurance against maintenance delays.
- What is the difference between flat head and button head screws in RC applications? — Flat head (countersunk) screws like these sit flush with the mounting surface, providing a low-profile fastening solution that prevents snagging and reduces aerodynamic drag on RC vehicles. Button head screws protrude above the surface, which can catch on components or reduce clearance. For ARRMA vehicles, flat head screws are specified for critical mounting points where space is limited.
- Are these screws suitable for beginners working on RC cars for the first time? — Yes, absolutely. These are standard maintenance screws designed for straightforward assembly and disassembly. The hex driver design makes them easy to install with common tools, and the precise manufacturing means they don't require excessive force, making them ideal for newcomers to RC vehicle maintenance who are learning basic servicing skills.
- How many times can I reuse these screws? — The super-strong steel construction allows these screws to be repeatedly assembled and disassembled many times without stripping, provided you use the correct size hex driver and don't over-tighten. However, if you notice the threads becoming loose or damaged, replacement is straightforward and affordable with this 10-pack.
