Overview

The Traxxas Screws, 3x8mm flat-head machine (hex drive) (6 pcs) TRX3931 are essential replacement parts for RC car owners across the UK who demand reliability and precision in their models. Whether you're maintaining a Traxxas Rustler, Slash, TRX-4 crawler, or Ford Fiesta ST Rally car, these genuine OEM fasteners ensure your RC vehicle stays in peak condition. Flat-head machine screws are critical components in RC car assembly and maintenance, holding together everything from chassis components to body panels and internal mechanisms. When you're investing in a quality ready to run RC car or brushless RC model, using genuine Traxxas replacement parts like these screws ensures longevity and performance consistency across seasons of bashing or racing.

These screws are manufactured to exacting Traxxas standards and are the original equipment fasteners used in countless RC models from the company's extensive range. For anyone building, rebuilding, or maintaining an RC vehicle in the UK, having a spare set of these crucial components in your spares box is smart preventative maintenance. A single damaged or stripped screw can compromise the structural integrity of your model, making these affordable replacements an investment in your RC hobby's long-term enjoyment.

RC enthusiasts, whether running competitive race kits, weekend bashers, or serious crawlers, understand that the smallest components often make the biggest difference. These Traxxas 3x8mm screws deliver the security, precision fit, and durability that serious hobbyists expect from genuine manufacturer parts.

Key Features

• 3x8mm Flat-Head Design — The 3mm diameter and 8mm length specification ensures these screws fit perfectly into Traxxas chassis components, body mounts, and internal mechanisms without binding or stripping, making them ideal replacement parts for maintaining RC cars used across the UK.
• Hex-Drive Heads — The hex socket drive head design allows for precise, secure fastening with a hex key or driver bit, preventing the rounding out or slipping that can occur with Phillips or flathead screws, ensuring your RC vehicle stays reliably assembled during high-speed runs.
• Machine Thread Construction — Machine-threaded fasteners provide consistent, reliable engagement with threaded holes in your RC car's chassis and components, creating secure connections that can withstand the vibration and impacts inherent to RC vehicle use.
• Genuine Traxxas OEM Parts — These are the exact same fasteners used by Traxxas in their factory assembly, guaranteeing compatibility with every model they're specified for, from brushless RC short course trucks to electric crawlers and rally cars.
• Pack of Six Screws — With six screws per pack, you have enough spares to replace multiple fasteners or maintain several repair kits, ensuring you're never caught short during maintenance or repairs to your ready to run RC vehicle.
• Black Finish — The black coating provides both aesthetic consistency with Traxxas RC models and protective corrosion resistance, helping the screws maintain their appearance and function through extended use in outdoor RC environments.

Technical Performance

These Traxxas flat-head machine screws are engineered to the precise tolerances required for modern RC vehicle construction. At M3 size (3mm diameter) with an 8mm length, they slot seamlessly into the many threaded mounting points found throughout Traxxas chassis and body components. The hex-drive design is particularly important in RC applications where fasteners are frequently removed and reinstalled during maintenance, repairs, and upgrades—the hex socket grips securely without the cam-out problems associated with Phillips heads or the shallow engagement of flathead screws. The machine thread profile means these screws cut clean, consistent threads in factory-drilled holes, creating a secure fit that doesn't loosen under the constant vibration and impacts experienced by RC cars during high-speed running, jumping, and bashing. Whether you're securing body panels on a brushless RC short course truck, attaching components to a TRX-4 crawler, or maintaining a Rustler Ultimate VXL 4x4, these fasteners deliver the reliability that keeps your RC vehicle performing at its best across endless UK driving sessions.

• How often should I replace these screws on my RC car? — Regular inspection is recommended, especially after heavy use, crashes, or when performing maintenance. Replace any screw that shows signs of stripping, corrosion, or damage. For active RC hobbyists in the UK, keeping a spare pack in your maintenance kit is wise preventative practice.
• Why is the hex-drive design better than Phillips or flathead screws? — The hex socket provides superior grip and engagement compared to Phillips or flathead designs, significantly reducing the risk of the driver slipping or the screw head rounding out during repeated fastening and unfastening cycles common in RC maintenance and repair work.
• What size hex key do I need to use with these screws? — The hex-drive heads on 3x8mm machine screws typically accept a 2.0mm or 2.5mm hex key, though you should verify with your specific Traxxas model documentation. A quality hex driver set is essential for any RC hobbyist's toolkit.
• Can I use these screws on other RC brands besides Traxxas? — While these are Traxxas-specific fasteners, other RC brands may use M3 x 8mm machine screws with hex drives. However, to guarantee fit and function, use only the manufacturer-specified parts for your particular RC vehicle model.
