Key Features
- Precision Hex Head Design — The hex socket design allows you to use standard hex keys (Allen keys) for installation and removal, providing excellent grip and reducing the risk of slipping or stripping the screw head during maintenance work on your RC car or truck.
- Precision Thread — These screws feature precisely machined threads that ensure consistent engagement with threaded holes throughout your ARRMA vehicle, preventing cross-threading and providing secure fastening that won't loosen during active use.
- Super-Tough Material Construction — Manufactured from hardened steel and high-quality material formulations, these screws resist corrosion, vibration-induced loosening, and the stresses of aggressive RC driving, ensuring they maintain their integrity through multiple disassembly and reassembly cycles.
- Flat Head Countersunk Design — The countersunk profile sits flush with the surface of components, preventing snagging, reducing aerodynamic drag on sensitive body panels, and maintaining the aesthetic integrity of your RC model.
- M3x12mm Specification — This size specification is one of the most frequently used fasteners across ARRMA's comprehensive product range, from compact 1/10 scale models to large 1/7 and 1/8 scale vehicles, making this a versatile addition to any RC spares box.
- Pack of 10 — Each pack includes ten screws, providing sufficient quantity for complete component reassembly, multiple repair cycles, or building up a proper spare parts inventory that ensures you're never left without essential fasteners.
Technical Performance
These ARRMA flat head screws represent genuine OEM (original equipment manufacturer) components engineered to the same specifications and tolerances as those supplied with new vehicles. The M3x12mm dimensions refer to a metric specification where the 3 indicates a 3mm nominal diameter and the 12 represents a 12mm length, a sizing standard recognised across professional RC racing and hobbyist applications throughout the UK and globally. The precision hex head accepts standard metric hex keys, whilst the countersunk flat head profile ensures components sit flush without proud fastener heads that could interfere with assembly tolerances or vibrate loose. The super-tough material specification means these screws have been hardened and treated to resist the corrosive environments RC vehicles encounter, whether from salt spray at coastal UK locations, moisture from outdoor tracks, or the intense vibration frequencies generated by brushless motors running at thousands of RPM. The precision threading ensures compatibility across all ARRMA models that specify this screw size, from entry-level brushed RTR models through to professional-grade 6S and 8S brushless vehicles like the KRATON 6S EXB, NOTORIOUS 6S, OUTCAST 6S EXB, TALION 6S EXB, TYPHON 6S, MOJAVE 6S, and the high-performance LIMITLESS and INFRACTION platforms. Whether your ARRMA vehicle uses brushless technology with advanced electronic speed controllers or the more straightforward brushed motor systems, these fasteners are engineered to handle repeated assembly and disassembly without degradation.
