Fastrax M3 Blue Flanged Locknuts Pack of 4 Locking RC Hardware FTM3BF

Overview

The Fastrax M3 Blue Flanged Locknuts are essential hardware components designed for RC enthusiasts who demand quality and reliability in their RC car builds. Whether you're a seasoned RC competitor fine-tuning a 1/10 scale buggy, setting up a 1/8 truggy for weekend bashing, or maintaining your RC crawler, these precision-engineered locknuts are indispensable for keeping your RC vehicle's fasteners secure during high-speed runs and aggressive cornering. Fastrax has established itself as a trusted manufacturer of RC spares and upgrades across the UK RC community, and these flanged locknuts represent the attention to detail that serious hobbyists expect when building or maintaining their RC models.

Available in an eye-catching blue colour that complements modern anodised aluminium chassis parts and blue-themed RC builds, these M3 flanged locknuts provide both functional security and aesthetic appeal. The pack of four gives you enough hardware for multiple suspension points, drive components, or other critical fastening applications on your RC car. If you're building a high-performance RC buggy, setting up a new RC truck, or simply restocking your pit box with quality spares, the Fastrax M3 Blue Flanged Locknuts are a cost-effective solution that ensures your build stays tight and secure through every corner and jump.

For UK RC car enthusiasts shopping for spares and tune-ups, Fastrax offers a comprehensive range of hardware options across different sizes and colours, allowing you to match your build aesthetic whilst maintaining the same proven quality standard. These locknuts are manufactured to tight tolerances and have been proven in competition environments across Europe, making them a reliable choice whether you're a beginner learning the basics of RC maintenance or an experienced racer preparing for the next event.

Key Features

• M3 Thread Size — The M3 metric thread size is one of the most commonly used fastener dimensions in RC car builds, making these locknuts compatible with a wide range of suspension arms, turnbuckles, shock towers and other chassis components across most 1/10 and smaller scale RC vehicles.
• Flanged Design — The flanged nut profile provides a larger bearing surface than standard locknuts, distributing clamping force more evenly across the component being fastened and reducing the risk of pulling through softer aluminium or composite materials commonly found in RC car parts.
• Locking Feature — Built-in nylon locking insert or equivalent mechanism prevents the nut from vibrating loose during aggressive driving, high-speed running, and the constant vibration cycles that RC cars experience on rough terrain, ensuring fasteners remain secure without requiring regular re-tightening.
• Bright Blue Finish — The vibrant blue anodised finish matches modern aluminium upgrade parts and allows you to create a cohesive colour-coordinated build aesthetic whilst easily identifying these fasteners in your parts box during assembly and maintenance.
• Pack of Four — Each pack contains four locknuts, providing enough hardware for multiple installation points such as suspension mounting, shock tower fastening, or chassis component attachment on a single RC vehicle, or allowing you to stock spares for future builds.
• Precision Manufacturing — Fastrax locknuts are engineered to tight tolerances ensuring consistent thread engagement, reliable locking performance, and compatibility with standard RC hardware and components without stripping or binding during installation or use.

Technical Performance

The Fastrax M3 Blue Flanged Locknuts represent precision hardware engineering specifically optimised for the demanding environment of RC car racing and recreational driving. The M3 metric thread specification is the industry standard for mid-scale RC components, making these nuts compatible with suspension arms, turnbuckles, shock mounting points, and chassis fasteners across a comprehensive range of RC buggy, truck, truggy and crawler platforms. The flanged design significantly improves clamping performance by increasing the surface area in contact with the fastened component, which is particularly important when working with anodised aluminium parts that can sometimes be prone to fastener pull-through if adequate bearing surface is not provided. The integrated locking mechanism, whether a nylon insert or equivalent design, provides vibration resistance that keeps fasteners secure during the intense vibration cycles generated by high-speed running, rough terrain impacts, and aggressive acceleration and deceleration cycles that RC cars routinely experience. The blue anodised finish offers both aesthetic appeal and corrosion resistance, protecting the steel fastener underneath from moisture and oxidation whilst providing visual continuity with modern RC upgrade parts and blue-themed vehicle builds. These locknuts are manufactured to the exacting standards expected by competition-level RC racers and recreational enthusiasts alike, ensuring reliable performance across countless driving sessions and maintenance cycles.

Frequently Asked Questions

• What RC vehicles can I use M3 flanged locknuts on? — M3 locknuts are compatible with most 1/10 scale RC buggies, trucks, truggies and smaller crawlers, as well as 1/8 scale vehicles that use M3 fasteners. They work perfectly on brands including Traxxas, ARRMA, Team Losi, Team Associated, Kyosho and other major RC manufacturers. Check your vehicle's manual or parts diagram to confirm M3 compatibility before purchasing.
• Why should I use flanged locknuts instead of standard locknuts? — Flanged locknuts provide a larger bearing surface that distributes clamping force more evenly, reducing the risk of pulling through softer materials like anodised aluminium common in RC parts. They also improve vibration resistance and provide a more professional finished appearance on your RC build.
• How do I know when to replace locknuts? — If the locking insert becomes stripped and nuts spin freely without tightening, or if threads become damaged from repeated tightening and loosening, it's time to replace them. Having spare locknuts in your pit box ensures you can quickly swap out damaged fasteners during maintenance or at the track.
• Will these locknuts work with turnbuckles and suspension arms? — Yes, M3 flanged locknuts are ideal for securing turnbuckles on suspension linkages, fastening suspension arms to the chassis, and securing shock mounting points. They provide reliable vibration resistance in these critical applications.
• Can I use these multiple times? — Yes, these are reusable locknuts suitable for repeated assembly and disassembly. However, if the nylon locking insert becomes stripped over time from multiple use cycles, the locking effectiveness diminishes and replacement is recommended.
• How do these compare to non-flanged M3 locknuts? — The flanged design provides a significantly larger clamping surface compared to standard locknuts, offering better load distribution, reduced risk of component pull-through, and improved vibration resistance in the critical fastening points found on RC vehicles.
