Traxxas Grub Screws 3x25mm and 3mm Nylon Locknuts Set TRX3962

Overview

The Traxxas Set (grub) screws, 3x25mm (8 pcs) / 3mm nylon locknuts (8 pcs) TRX3962 is an essential maintenance and repair component for RC enthusiasts across the UK who rely on Traxxas vehicles. Whether you operate a high-performance RC car, truck, buggy or crawler, having quality fasteners on hand is crucial for keeping your model in peak condition. Traxxas grub screws and nylon locknuts are precision-engineered components designed to withstand the rigours of competitive racing and weekend bashing alike, making this set an indispensable addition to any RC hobbyist's spare parts collection.

Grub screws are headless fasteners that sit flush with the surface they're securing, making them ideal for use in RC models where space is limited and a traditional headed screw would interfere with moving parts or clearance. The 3x25mm size featured in this set is a common specification across many Traxxas models, from entry-level ready to run RC vehicles to advanced competition-grade machines. If you're building a new Traxxas RC car UK model or maintaining an existing fleet, these fasteners ensure secure assembly and reliable performance.

Complementing the grub screws, this set includes 3mm nylon locknuts—specially designed fasteners that incorporate a nylon insert to prevent vibration-induced loosening. The nylon material provides a self-locking feature without requiring threadlocker adhesives, which is particularly valuable during intensive RC racing or high-speed off-road bashing. This combination of eight grub screws and eight matching nylon locknuts provides excellent value and ensures you have backup fasteners when replacements are needed due to wear or loss.

Key Features

• Traxxas Original Equipment — These are genuine Traxxas components manufactured to the exact specifications required for compatible Traxxas RC models, ensuring proper fitment and reliable performance on your ready to run RC vehicle.
• Grub Screws 3x25mm (8 pieces) — Headless fasteners measuring 3mm in diameter by 25mm in length, providing a flush fit that doesn't protrude or catch on surrounding components, which is essential in compact RC chassis design.
• Nylon Locknuts 3mm (8 pieces) — Self-locking fasteners featuring a nylon insert that prevents nuts from vibrating loose during high-intensity driving, eliminating the need for separate threadlocker compounds and making assembly and maintenance faster.
• Precision Manufacturing — Manufactured to exacting tolerances, these fasteners ensure repeatable, secure assembly and maintain consistent clamping force across multiple installation and removal cycles, essential for reliable RC performance.
• Vibration Resistance — The combination of quality grub screws and nylon locknuts resists the constant vibrations experienced during RC car operation, particularly important for off-road bashers and competition-grade machines.
• Complete Set Value — With 8 grub screws and 8 matching nylon locknuts included, this set provides complete pairs for multiple assemblies or spares when fasteners are lost or damaged during RC operations.

Technical Performance

The Traxxas Set (grub) screws, 3x25mm / 3mm nylon locknuts represents quality engineering designed specifically for the demanding requirements of RC hobby use. The 3x25mm specification places these grub screws in the mid-range size category, making them suitable for numerous Traxxas models including various truck, buggy and car platforms. The headless design of grub screws eliminates protruding screw heads that could interfere with suspension movement, wheel clearance or other critical components, which is particularly important in tightly packaged RC chassis designs. The 3mm nylon locknuts feature engineering-grade polymer inserts that provide consistent self-locking performance across hundreds of assembly/disassembly cycles, maintaining clamp force without degradation. The combination of steel fasteners and engineered nylon components results in reliable, repeatable performance whether you're fine-tuning a brushless RC buggy for competition or maintaining a high-speed RC truck for recreational bashing. These fasteners maintain their integrity under the thermal and mechanical stress associated with RC operations, including exposure to dust, dirt, moisture and rapid temperature changes during extended outdoor use.

Frequently Asked Questions

• What are grub screws used for in RC models? — Grub screws are headless fasteners designed to sit flush with the surface they secure, making them ideal for RC applications where traditional screw heads would create clearance issues or interfere with moving parts. They're commonly used for securing motor shafts, adjusting suspension components and attaching various internal assemblies within RC cars, trucks and buggies.
• Why do I need nylon locknuts instead of regular nuts? — Nylon locknuts include an engineered nylon insert that prevents the nut from loosening due to vibration. During RC operation, constant vibrations from the motor, bumps and terrain impact can cause regular nuts to gradually work loose and fall off. Self-locking nylon locknuts eliminate this problem without requiring threadlocker adhesives, making assembly and maintenance faster and cleaner.
• Are these fasteners compatible with all Traxxas RC models? — The 3x25mm grub screw and 3mm locknut sizes are common specifications across many Traxxas models, but compatibility depends on your specific vehicle. We recommend checking your Traxxas model's parts list or contacting our experienced team to confirm these fasteners are appropriate for your particular RC car, truck or buggy.
• How many times can I reuse these fasteners? — Quality Traxxas fasteners like these are designed to withstand repeated assembly and disassembly cycles. The steel grub screws maintain their integrity across hundreds of uses, while the nylon locknuts continue to provide self-locking performance. However, if a nut becomes stripped or a screw becomes damaged or worn, replacement is straightforward with this spare set on hand.
• Should I use threadlocker with these nylon locknuts? — No, the nylon insert provides self-locking action without additional adhesives. Using threadlocker is unnecessary and may complicate future disassembly. However, if you're installing these in a location subject to extreme vibration or you prefer extra security, a light threadlocker can be used at your discretion.
• Where can I use this set on my RC model? — These fasteners suit numerous assembly points across Traxxas RC vehicles, including motor mounting, suspension adjustments, shock tower attachment, servo mounts and internal drivetrain components. Check your specific model's manual for locations requiring 3x25mm grub screws and 3mm locknuts.
