Technical Performance

These Associated Factory Team M3 Locknuts represent precision engineering at its finest. The blue aluminium construction delivers optimal performance characteristics for RC applications where weight, strength and vibration resistance are critical. Unlike standard nuts that can gradually loosen under the intense mechanical stress of RC vehicle operation, these locknuts feature a locking mechanism that maintains fastener integrity even during high-speed runs, aggressive cornering, and rough terrain navigation. The M3 metric thread specification means they work seamlessly with M3 bolts, studs and fastening points found throughout modern RC car, buggy, truck and crawler designs. The lightweight nature of aluminium compared to steel alternatives makes these locknuts particularly valuable for competition-oriented builders and racers who understand that reducing unsprung weight contributes directly to improved suspension response, faster acceleration and better handling characteristics. For those running brushless motors on high-performance RC vehicles, maintaining secure fasteners is essential to prevent component shifts that could affect driveline alignment, suspension geometry or drivetrain efficiency.

Frequently Asked Questions

• What is an M3 locknut and why do I need it for my RC car UK? — An M3 locknut is a fastener with an integrated locking feature designed to prevent loosening under vibration. RC vehicles experience constant movement and shock, which naturally tries to unscrew standard nuts. Locknuts resist this, keeping your suspension, drivetrain and chassis components securely fastened during operation. They're essential for reliability on any serious RC car, buggy or truck.
• Will these Associated M3 locknuts fit my RC model? — These M3 locknuts are compatible with any Associated RC model or general RC application that uses M3 metric thread fasteners. This includes a comprehensive range of Team Associated vehicles from entry-level buggies to competition-grade touring cars and monster trucks. If your model uses M3 bolts or studs, these locknuts will work perfectly.
• Are these genuine Associated parts? — Yes, these are genuine Associated Factory Team locknuts, part number AS31550. They are manufactured by Team Associated and represent the same quality standards used in their factory racing programs and professional builds.
• How many locknuts come in a package? — The source information indicates this is a pack of Associated Factory Team M3 Locknuts, though the exact quantity per pack is not specified in available documentation. We recommend contacting our team at RC Model Shop on 01543 577278 for specific quantity details.
• Why choose aluminium over steel locknuts? — Aluminium locknuts offer several advantages for RC applications: they are significantly lighter than steel, which reduces unsprung weight and improves suspension response and acceleration; they are easier to install and remove compared to heavier steel alternatives; and they provide sufficient strength for RC fastening applications while contributing to overall weight reduction in your build.
• Are these suitable for competition RC racing? — Absolutely. These are genuine Factory Team parts, meaning they are engineered to competition standards and are used in professional and semi-professional RC racing applications. The vibration-resistant design makes them ideal for high-performance builds where reliability under extreme conditions is essential.
