Technical Performance
The Team Associated M4 Locknut AS89216 is engineered with precision manufacturing standards that meet the demanding requirements of RC motorsport and recreational driving. M4 locknuts feature a self-locking mechanism that provides reliable fastening under the constant vibration and dynamic forces experienced during RC car operation. Unlike standard nuts, locknuts incorporate a nylon insert or deformed thread design that creates friction and resistance to loosening, ensuring that critical components such as suspension arms, steering linkages, shock absorbers and chassis fasteners remain firmly secured throughout extended running sessions. This is particularly important for competitive RC racers and serious hobbyists who operate their vehicles at high speeds or in challenging terrain where impact forces and vibration are continuous. The genuine Team Associated specification ensures these locknuts meet exact material standards and manufacturing tolerances, providing consistent performance across all applications. Whether you're assembling a new RC buggy, maintaining an existing RC car, or replacing worn fasteners on a trail truck, these M4 locknuts deliver the dependable quality and security you need to keep your vehicle performing reliably.

Frequently Asked Questions
- What are M4 locknuts used for in RC cars? — M4 locknuts are self-locking fasteners specifically designed to prevent standard nuts from loosening under vibration during RC car operation. They are essential components in RC vehicles, used to secure critical parts such as suspension components, steering linkages, shock absorbers and chassis fasteners. Without locknuts, standard nuts can gradually loosen due to the constant vibration and impact forces experienced during RC driving, which could lead to component failure or vehicle malfunction.
- Are these locknuts compatible with my RC vehicle? — The Team Associated M4 Locknut AS89216 is compatible with RC models that use M4 threaded hardware from Team Associated and other leading RC brands. These locknuts are suitable for a wide range of RC cars, buggies, trucks and crawlers including popular Team Associated platforms such as the RC8B4, RC8T4, RC8B3, RC8T3, RC8B3.1, RC8T3.1E, RC8T3.2E, RC8B4E, RC8T4E, RC8B4.1, RC8B4.1E, RC8B3.1E and Element Enduro range vehicles including the Sendero, Trailwalker, Gatekeeper, Knightrunner, Bushido, Ecto Trail Truck, Utron SE, Zuul and Zuul IFS2 models.
- Do I need genuine Team Associated locknuts or can I use generic alternatives? — Whilst generic M4 locknuts may appear to work initially, choosing genuine Team Associated parts ensures you receive components that meet the exact specifications and quality standards your RC vehicle was engineered to use. Genuine parts provide reliable fitment, consistent performance and the assurance that you're using exactly the right component for your model. For serious RC enthusiasts who demand reliability and performance, genuine replacement parts are always the recommended choice.
- How many locknuts come in a pack? — The product listing indicates this is a replacement fastener component, though the exact quantity per pack is not specified in the available information. We recommend contacting RC Model Shop directly on 01543 577278 to confirm the pack quantity before ordering.
- How do I install M4 locknuts? — M4 locknuts are installed like standard nuts onto M4 threaded bolts or studs. Thread the locknut onto the fastener until hand-tight, then use an appropriate spanner or socket to tighten to the required tension. The self-locking mechanism engages as you tighten the nut, providing resistance and preventing it from loosening under vibration during RC car operation.
