Technical Performance
The ARRMA Wheel Hex Metal 12mm represents a fundamental engineering solution for connecting wheels to axles in modern RC vehicles. At 12mm, this hex size is the industry standard for 1/10 and 1/8 scale RC cars, trucks and buggies manufactured to competitive specifications. The aluminium construction provides optimal material properties: sufficient strength to handle the forces generated by 3S and higher LiPo battery systems powering brushless motors, whilst remaining lightweight enough that it doesn't compromise acceleration or handling characteristics. The precision manufacturing means that tolerances are tight enough to prevent the play and slop that can develop in lesser-quality components, which is crucial when you're driving fast ready to run RC vehicles over rough terrain. The included 10 x 2.5mm steel pins are specifically dimensioned to provide maximum grip on the axle whilst maintaining the ability to be installed and removed without excessive force or tool damage. The set screws are M3 x 3mm specification, matching ARRMA's engineering standards across their entire vehicle range from the entry-level brushed models through to the high-performance brushless systems. This component works in harmony with ARRMA's drivetrain systems whether you're running a 2WD or 4WD configuration, and whether your vehicle features a brushed or brushless motor. The combination of aluminium hex body, steel pin and set screw creates a system that balances durability, weight savings and maintenance accessibility.

Frequently Asked Questions
- Will this ARRMA wheel hex fit my 1/10 RC monster truck or short course vehicle? — Yes, the 12mm hex specification is the standard across ARRMA's 1/10 scale vehicle range including the Granite, Senton, Vorteks, Big Rock, Fury and Gorgon models, as well as select 1/8 scale vehicles like the Infraction and Vendetta. Check your vehicle's model number against the fitment list provided to confirm compatibility.
- Is this suitable for beginners working on their RC cars? — Absolutely. The wheel hex is one of the most straightforward components to install on any RC vehicle. Once you understand the basic procedure of sliding the hex onto the axle, inserting the pin, and tightening the set screw, you'll have confidence replacing or upgrading this component. Our team at RC Model Shop can provide guidance if you're uncertain about installation.
- Why would I need replacement wheel hexes for my ready to run ARRMA vehicle? — Wheel hexes can experience wear over time, particularly if you're an aggressive driver who regularly tackles rough terrain, jumps or high-speed runs. They can also become damaged in crashes. Stocking spare hexes means you can quickly get back on the track without waiting for replacement parts. Additionally, some owners purchase spare hexes to experiment with different wheel and tyre combinations without constantly changing components.
- What is the difference between the 12mm aluminium hex and other hex options? — The 12mm size is ARRMA's standard across most of their vehicle range. Aluminium construction provides a balance of strength and weight that works perfectly with modern brushless systems and 3S LiPo batteries. ARRMA engineers their vehicles around this specification, so using genuine ARRMA hexes ensures perfect fitment and performance.
- How do I know if my ARRMA vehicle uses 12mm hexes? — The fitment table on the product page lists all compatible ARRMA models. Common compatible vehicles include the Big Rock series, Granite series, Senton series, Vorteks series, Fury series, Gorgon series, Infraction series and Vendetta series. If your model is listed, the 12mm hex is the correct choice.
- Are these genuine ARRMA parts or aftermarket alternatives? — These are official ARRMA parts, manufactured to OEM specifications and distributed through authorised retailers. Genuine parts ensure perfect compatibility, optimal performance and reliability with your ARRMA vehicle.
