Overview
The FTX Flange Lock Nut M4 (6) is an essential replacement spare part for RC car enthusiasts and hobbyists in the UK who demand reliable, precision-engineered components. Whether you're maintaining your existing FTX RC model or building a custom setup, these M4 flange lock nuts provide the security and durability needed to keep your RC vehicle performing at its best. As a dedicated RC car UK retailer, we understand that quality spare parts are the foundation of any well-maintained ready to run RC car or upgrade project.
Flange lock nuts are critical fastening components used throughout RC vehicles, particularly in suspension assemblies, drivetrain connections and chassis mounting points. The flange design distributes load more evenly than standard nuts, reducing the risk of fastener loosening due to vibration—a common issue in high-performance RC applications. This pack contains six M4 nuts, giving you multiple spares for repairs, upgrades or building multiple vehicles. For anyone serious about RC car maintenance or restoration, having quality replacement nuts on hand is simply good practice.
At RC Model Shop, we stock genuine FTX spare parts because we know that using authentic components ensures compatibility and performance. Whether you're replacing worn fasteners on your brushless RC car or undertaking a comprehensive rebuild, the FTX Flange Lock Nut M4 delivers the reliability and value that discerning RC hobbyists expect.
Key Features
- M4 Thread Size — This is the standard metric M4 specification, making it compatible with the wide range of FTX RC vehicle models and general hobby RC applications where M4 fasteners are specified in assembly instructions.
- Flange Design — The flange around the nut base spreads clamping force over a larger surface area, which is essential for preventing fasteners from working loose under the constant vibration and shock loads that RC vehicles experience during operation.
- Pack of Six Nuts — Multiple spares in one pack means you have backups for replacements, repairs or building multiple vehicles, making this an economical choice for serious RC enthusiasts.
- Lock Function — These flange lock nuts incorporate a locking mechanism that resists vibration-induced loosening, providing superior security compared to standard hex nuts and reducing the need for thread-locking compound.
- Genuine FTX Component — As an authorised FTX retailer, we supply only genuine FTX spares that meet the manufacturer's specifications and quality standards, ensuring perfect fit and reliable performance in your RC vehicle.
Technical Performance
The FTX Flange Lock Nut M4 represents precision engineering at the component level. Designed specifically for use in RC car applications where vibration and impact loads are significant stressors, these nuts feature a flange that acts as a built-in washer, distributing the clamping force across a wider area of the mounting surface. This design is particularly important in RC vehicles because the constant acceleration, braking, cornering and suspension articulation creates sustained vibration that can gradually loosen standard fasteners. The lock function integrated into the nut's design—whether through a nylon insert, deformed thread, or similar mechanism—provides additional insurance against loosening. The M4 metric thread is a standard sizing used extensively throughout FTX's product range and is compatible with numerous RC vehicles and general hobby applications. These nuts are manufactured to tight tolerances to ensure they engage smoothly with M4 bolts and screws without binding or cross-threading. The flange design also helps protect the mounting surface from damage that can occur when standard nuts are tightened, particularly on plastic or softer composite chassis materials commonly found in RC cars. For anyone maintaining, repairing or customising their RC vehicle, having quality replacement fasteners is essential to maintaining structural integrity and reliability.

Frequently Asked Questions
- What is a flange lock nut and why do I need it? — A flange lock nut combines the functions of a standard hex nut with an integrated washer (the flange) and a locking mechanism. The flange distributes clamping force over a larger area, reducing stress on mounting surfaces, whilst the locking feature resists vibration-induced loosening. In RC vehicles, which experience constant vibration during operation, flange lock nuts are superior to standard nuts because they stay tight longer and require less frequent re-tightening.
- Are these compatible with my FTX RC vehicle? — The M4 thread size is standard across many FTX RC models including the Outback range, Carnage, Bugsta, and numerous others. Check your vehicle's manual or spare parts diagram to confirm M4 fasteners are specified for the component you're replacing. If you're unsure, contact our expert team at RC Model Shop and we'll help you identify the correct part.
- How many spares do I actually need? — This pack contains six nuts, which is ideal for keeping spares on hand. An average RC vehicle uses multiple M4 fasteners throughout its construction, so having several backups ensures you can complete repairs and maintenance without waiting for delivery. Many serious RC hobbyists buy multiple packs to maintain comprehensive spare parts kits.
- Do I need thread-locking compound with flange lock nuts? — The locking mechanism built into flange lock nuts provides significant resistance to loosening, so thread-locking compound is generally not required. However, if you're working on critical safety-related fasteners or want maximum insurance against loosening in extreme racing conditions, you can apply a small amount of thread-locking compound to the bolt before installation—just be sure to use removable-strength compound so you can service the part later.
- Can I use these on other RC models or general hobby projects? — Yes, the M4 thread is a standard metric specification used across many RC brands and hobby applications. If your RC car or project requires M4 nuts, these genuine FTX components will work perfectly. The flange design makes them suitable for any application where vibration resistance is important.
