Fastrax M3 Gold Locknuts Nylon Locking Flanged Fasteners Pack of 4 FASTM3G

Overview

The Fastrax M3 Gold Locknuts are essential fastening components designed for RC enthusiasts and hobbyists who demand reliable, durable hardware for their remote control vehicles. Whether you're a seasoned RC car UK competitor, a weekend basher, or someone just getting started with RC models, these precision-engineered locknuts provide the secure fastening your RC projects require. Gold anodised finish not only looks fantastic on your build but also offers superior corrosion resistance, ensuring your RC vehicle maintains its professional appearance through countless hours of use in varying weather conditions.

These M3 nylon locking fasteners are widely compatible with numerous RC platforms and are trusted by builders across the UK who understand that quality hardware is the foundation of a reliable RC setup. Whether you're building a brushless RC crawler, maintaining a Traxxas TRX-4, or customising an Axial racing model, these locknuts provide the peace of mind that your fasteners will stay secure during aggressive driving. The nylon locking insert prevents vibration-induced loosening, a critical feature for any RC car UK application where chassis components, suspension parts, or electronic mounts need absolute security.

At just £2.49 for a pack of four, these Fastrax M3 Gold Locknuts represent outstanding value for money and should be part of every RC enthusiast's spares box. Whether you're replacing worn fasteners, building a new model from scratch, or expanding your spare parts collection, these gold-finished locking nuts are an investment in reliability and longevity for your RC hobby projects.

Key Features

• Nylon Locking Insert (Nyloc Design) — The integrated nylon insert creates friction that prevents the nut from loosening due to vibration, which is essential for RC applications where constant movement and impacts are inevitable. This self-locking mechanism means your fasteners stay secure without requiring threadlocker compound.
• Gold Anodised Finish — Beyond aesthetics, the gold anodised coating provides excellent corrosion resistance and durability, protecting the fastener from oxidation, moisture, and the wear that comes with outdoor RC use. This finish maintains its appearance through multiple seasons of active use.
• M3 Thread Size — The M3 specification ensures compatibility with a wide range of RC platforms and components, making these locknuts a versatile addition to any builder's hardware collection for use across different vehicle types and scales.
• Flanged Design — The flanged head creates a larger bearing surface, distributing load more effectively and preventing fasteners from pulling through softer materials common in RC models and composite parts.
• Pack of Four — Each pack contains four locknuts, providing sufficient fasteners for multiple applications or allowing you to keep spares on hand for maintenance and repairs on your RC vehicles.
• Fastrax Quality — Fastrax is a recognised manufacturer of RC components and spares trusted by hobby shops and enthusiasts throughout the UK, ensuring you're purchasing genuine, quality hardware manufactured to specification.

Technical Performance

The Fastrax M3 Gold Locknuts are precision-manufactured fastening components engineered specifically for the demands of remote control vehicles. The M3 thread size represents a standard fastener diameter used extensively across RC models ranging from small electric crawlers to larger brushless RC trucks and buggies. The nylon locking insert embedded in each nut works through a simple but effective principle: as the nut is threaded onto a bolt, the nylon compresses slightly, creating friction that resists rotational movement caused by vibration and impact during vehicle operation. This is far superior to standard non-locking nuts which can gradually vibrate loose through the punishment of jumps, high-speed runs, and rough terrain navigation. The gold anodised finish is applied through an electrochemical process that creates a protective oxide layer, significantly improving the fastener's resistance to corrosion from moisture, saltwater exposure (if using your RC vehicle near coastal areas), and the various cleaning solutions used to maintain your models. The flanged head design increases the contact area between the nut and the component being fastened, which is particularly important when working with plastic chassis plates, delrin suspension components, or aluminium build plates commonly found on modern RC cars UK. The engineering quality ensures consistent fit and reliable performance across all fastening applications within compatible RC platforms.

Frequently Asked Questions

• Are these locknuts suitable for all my RC vehicles? — The M3 thread size makes these locknuts compatible with many RC platforms, particularly models that use metric fasteners in their suspension, chassis, and component mounting systems. They are specifically listed as compatible with the FTX Zorro Trophy Truck Brushless RTR and will work with numerous other Fastrax, Traxxas, Axial, Losi, and other popular RC brands that utilise M3 fasteners in their design. Always verify your specific model's fastener specifications before ordering.
• Why should I use locking nuts instead of standard nuts? — Locking nuts with nylon inserts prevent fasteners from vibrating loose during RC vehicle operation, which is critical for maintaining the structural integrity and safety of your model. Without locking fasteners, suspension components, chassis plates, and electronic mounts can gradually become loose, leading to poor handling, potential component failure, or even loss of vehicle control. The nylon insert provides a permanent self-locking mechanism without the need for additional threadlocker products.
• How many fasteners do I get in a pack? — Each pack contains four M3 Gold Locknuts, providing sufficient fasteners for multiple applications such as suspension mounting points, servo brackets, or electronic component securing points on your RC vehicle.
• Will these fit my specific RC model? — The M3 thread size is compatible with numerous RC models from major manufacturers. However, compatibility depends on your specific vehicle's fastener specifications. Check your model's parts diagram or manual to confirm it uses M3 fasteners before purchasing. The locknuts are confirmed compatible with the FTX Zorro Trophy Truck Brushless RTR.
• Can I reuse these locknuts? — While nylon locking nuts can technically be reused several times, the nylon insert gradually loses its locking effectiveness with each removal and reinstallation. For critical applications, it's recommended to replace locknuts periodically, particularly on high-vibration components. These packs of four make it easy to keep spare locknuts on hand for maintenance.
• Are these genuine Fastrax products? — Yes, when purchased from RC Model Shop, you are receiving genuine Fastrax components manufactured to original specification. The part number FASTM3G ensures you are ordering the correct authentic product.
