When you choose genuine ARRMA parts from RC Model Shop, you're choosing the same hardware trusted by RC car enthusiasts across the UK.
Key Features
- M4 Thread Type — The M4 metric thread specification ensures perfect compatibility with ARRMA wheel hubs and axles, guaranteeing a secure fit without forcing or stripping threads. This precise engineering means you can confidently install these nuts knowing they'll work seamlessly with your vehicle's suspension and drivetrain components.
- Black Anodised Finish — The black anodised coating provides more than just visual appeal; it protects the metal from corrosion and oxidation, which is especially important when your RC vehicle encounters water, mud, and harsh outdoor conditions during typical RC off-road adventures. This finish helps the nuts maintain their integrity and appearance over extended periods of use.
- Flanged Surface Design — The flanged head design features a wider bearing surface that distributes clamping force more effectively than standard nuts, preventing the nut from sinking into softer materials and reducing the risk of the wheel becoming loose during aggressive driving or high-speed runs. This enhanced closure security is particularly valuable when running your RC car on rough terrain or performing stunts.
- Pack of Four — With four nuts included, this pack provides everything needed to replace the fasteners on all four wheels of your 10th scale RC vehicle. This is the exact quantity required for a complete wheel replacement, making it an economical choice compared to purchasing nuts individually.
- Genuine OEM Hardware — As original equipment manufacturer parts, these nuts are the same fasteners supplied by ARRMA with new vehicles, guaranteeing authenticity, quality, and perfect fitment across the entire ARRMA range of 1/5 and 1/8 scale brushless RC trucks and buggies.
Technical Performance
These ARRMA Flange Lock Nuts 4mm represent precision fastening hardware engineered to the specifications required by modern 10th scale RC vehicles. The M4 thread specification is the industry standard for wheel fasteners on 1/8 and 1/10 scale RC cars, providing a balance between clamping force and material strength. The flanged design is critical to performance because it increases the surface area in contact with the wheel hub or mounting point, which distributes the clamping force more evenly and prevents the nut head from pulling through plastic or composite wheel materials. The black anodised finish adds approximately 10-25 micrometres of protective oxide coating, which significantly improves resistance to corrosion from moisture, dirt, and saltwater exposure. For competitive RC racing and high-performance bashing, using genuine OEM fasteners like these ensures that your wheel assembly maintains perfect concentricity and balance, which directly impacts handling, traction, and overall vehicle stability at high speeds. The manufacturing tolerances on M4 fasteners are typically held to ISO 4014 or equivalent standards, ensuring that each nut in the pack provides consistent engagement with your vehicle's threaded studs. Whether you're maintaining a 1/5 KRATON 8S, an OUTCAST 8S, or any brushless ARRMA truck in the range, these nuts represent an investment in reliability and longevity that will serve you well across countless RC car sessions and competitions throughout the UK.

Frequently Asked Questions
- What ARRMA models are these M4 flange nuts compatible with? — These nuts are standard OEM parts for a wide range of ARRMA 1/5 and 1/8 scale vehicles. According to ARRMA's official parts list, they are compatible with the 1/5 KRATON 8S 4X4 RTR, KRATON 8S EXB, KRATON 8S EXB AVC, OUTCAST 8S AVC RTR, OUTCAST 8S EXB, OUTCAST 8S EXB AVC, and numerous 1/8 scale models including the KRATON 6S, KRATON 6S EXB, NOTORIOUS 6S, OUTCAST 6S EXB AVC, TALION 6S EXB AVC, and TYPHON 6S variants. If you own any ARRMA brushless truck or buggy, these M4 nuts are almost certainly the correct replacement for your wheels.
- Why should I use genuine ARRMA flange lock nuts instead of generic replacements? — Genuine ARRMA parts are engineered to exact specifications and quality standards that match your vehicle's original components perfectly. Using OEM fasteners ensures proper fit, prevents thread stripping, maintains wheel balance and concentricity, and keeps your RC truck or buggy running safely at high speeds. Generic alternatives may have slightly different thread pitches or flanging dimensions that can cause loose wheels or damage to your expensive RC vehicle.
- How many wheels can I replace with one pack of four nuts? — One pack contains exactly four nuts, which is the correct quantity to replace fasteners on all four wheels of your RC car. Each wheel typically requires one nut, making this pack perfectly suited to a complete wheel refresh or replacement.
- What is the difference between flange nuts and standard nuts for RC wheels? — Flange nuts feature an integral washer-like flange at the base that spreads the clamping load over a larger area. This design is superior for RC applications because it prevents the nut from digging into plastic wheel hubs, reduces the chance of wheels working loose during aggressive driving, and provides superior holding power. Standard nuts lack this flange and are more prone to loosening on high-vibration RC vehicles.
- Are these nuts suitable for both 1/5 and 1/8 scale ARRMA vehicles? — Yes, M4 is the standard wheel fastener size across both 1/5 and 1/8 scale ARRMA brushless RC trucks and buggies. Whether you're running a massive 1/5 KRATON 8S or a compact 1/8 TYPHON, these M4 flange lock nuts will fit correctly.
- Do I need any special tools to install these nuts? — Installation requires only a 4mm hex socket or wrench, which is standard equipment in any RC tool kit. No specialised tools are needed; simply thread the nut onto your wheel hub stud and tighten with your preferred hex driver.
