Traxxas Grub Screws 4mm with Heavy Duty Threadlock 6 Piece Set TRX4897X

Overview

The Traxxas Screws set (grub), 4mm with heavy duty threadlock is an essential spare parts item for RC enthusiasts maintaining their Traxxas RC cars and trucks. These precision-engineered grub screws are designed to secure critical components on your RC model, ensuring reliability during intense off-road adventures and competitive racing. Whether you're running a brushless 4WD RC monster truck, a high-speed RC buggy, or any other Traxxas model, having quality replacement screws on hand is crucial for keeping your machine in peak condition. The inclusion of heavy duty threadlock means these screws stay put, even under the vibration and stress of aggressive driving.

Grub screws are small but vital fasteners that play an enormous role in the structural integrity of your RC vehicle. They're commonly used to secure motor pinions, wheel hubs, servo horns, and various other components that must remain absolutely fixed in place. When a grub screw loosens, it can lead to catastrophic failures mid-run, potentially damaging expensive components or losing your model altogether. This six-piece set from Traxxas provides you with quality spares to replace worn, stripped, or lost fasteners, keeping your RC car UK ready for the track or the bashing field.

The heavy duty threadlock applied to these screws is a game-changer for RC hobbyists who demand maximum reliability. Threadlock is a liquid adhesive applied to screw threads that prevents unintended loosening caused by vibration, whilst remaining removable when needed for maintenance or repairs. The heavy duty formula used here offers superior holding power compared to standard threadlock, making it perfect for the demanding environment of high-performance RC driving. Whether you're a weekend basher putting your ready to run RC through its paces or a serious competitor, these replacement screws should be in your spare parts box.

Key Features

• 4mm Grub Screw Size — These are 4mm grub screws, a common fastener size used throughout Traxxas vehicles for securing components like motor pinions, drive shafts, and servo horn attachments, ensuring compatibility with most Traxxas models.
• Heavy Duty Threadlock Included — Each screw is pre-treated with heavy duty threadlock compound, which prevents vibration-induced loosening whilst remaining removable with standard tools when you need to service or repair your RC model.
• Six-Piece Set — This pack contains six replacement grub screws, giving you multiple spares so you're never caught short mid-season or at a racing event.
• Genuine Traxxas Component — As an official Traxxas part, these screws meet the manufacturer's strict quality standards and are guaranteed to fit and function correctly on compatible Traxxas RC vehicles.

Technical Performance

These Traxxas grub screws represent the kind of small but critical engineering that separates reliable RC machines from unreliable ones. Whilst they may seem like simple fasteners, the application of heavy duty threadlock transforms them into semi-permanent fastening solutions that keep your RC vehicle's components securely locked in place during the most demanding driving conditions. The 4mm size makes these screws suitable for a wide range of Traxxas models, from lightweight 1/16 scale machines to larger 1/8 scale vehicles. The threadlock formula is specifically formulated to resist the constant vibration and shock loads that RC vehicles experience, whether you're bashing through rough terrain, competing on a racing circuit, or pushing your brushless RC motor to its maximum output. The screws are precision-manufactured from high-quality steel with a hardened finish that resists stripping and deformation, even when tightened to secure fit. The pre-application of heavy duty threadlock means you don't need to apply your own, saving time during assembly or maintenance and ensuring consistent, professional results every time. These are not cheap fasteners — they're engineered components that deserve their place in the toolbox of every serious RC enthusiast.

Frequently Asked Questions

• What exactly is a grub screw and where is it used on my RC car? — A grub screw is a headless fastener with a socket or slot drive, typically used to secure components that need to be held tight against a shaft or surface. On Traxxas vehicles, grub screws commonly secure motor pinions to the motor shaft, hold wheel hubs in place, attach servo horns, and fasten various drivetrain components. Because they're sunk flush with the component, they're ideal for applications where a protruding screw head would interfere with function.
• Why does threadlock matter on RC screws? — Threadlock is a chemical adhesive that locks threads together and prevents screws from vibrating loose. RC vehicles experience constant vibration and shock, so without threadlock, critical fasteners can gradually loosen during driving, potentially leading to component failure. Heavy duty threadlock offers superior holding strength compared to medium or light threadlock, making it essential for high-stress applications.
• Can I remove screws that have heavy duty threadlock applied? — Yes, absolutely. Heavy duty threadlock is designed to be semi-permanent, meaning it holds firmly during normal use but can still be removed with appropriate tools and effort. You simply need a correctly-sized hex key or Allen wrench to remove the screw, and it will come out with firm pressure. The threadlock doesn't create a permanent bond — it just prevents vibration-induced loosening.
• What Traxxas models are these screws compatible with? — The 4mm size means these screws are compatible with most Traxxas vehicle models across their entire range, including Traxxas monster trucks, buggies, truggies, crawlers, and stadiums trucks. If you're unsure whether these will fit your specific model, consult your vehicle's parts diagram or contact the team at RC Model Shop for guidance.
• How often should I replace grub screws on my RC vehicle? — Grub screws should be inspected regularly and replaced if they become stripped, corroded, or damaged. In high-performance racing environments, many competitors replace them each season as preventative maintenance. For casual bashers, replacement is typically only needed when a screw becomes defective or is lost.
• Is this suitable for beginners? — Yes, these replacement screws are suitable for RC enthusiasts at any skill level. They're a straightforward maintenance item that any RC hobbyist should keep in their spare parts collection. Beginners should familiarize themselves with where grub screws are located on their specific model and learn the correct torque settings to avoid over-tightening.
