Key Features

Using genuine parts protects your investment and ensures consistent performance.
• Button Head Design — The button head profile provides a clean, professional appearance whilst offering excellent holding power and durability during intense off-road RC driving. This design minimises snagging on terrain or obstacles compared to traditional socket head alternatives.

• Kingpin Application — These screws are specifically engineered as kingpin fasteners, meaning they secure the critical pivot points in your RC vehicle's suspension system where steering geometry and suspension travel are defined. Proper kingpin fastening is absolutely essential for safe, predictable handling.
• Pack of Eight — This generous eight-screw pack ensures you have multiple replacements for maintenance, repairs, and upgrades, plus spares for future sessions without needing to reorder frequently.

Technical Performance

FTX Outback Button Head Screw M3*6 components are engineered using high-strength materials selected specifically to withstand the constant stress cycling experienced during RC off-road driving. The M3 metric thread provides a fine pitch that allows precise adjustment of kingpin preload, critical for tuning suspension responsiveness and steering feel. Button head screws distribute clamping force across a wider area than equivalent socket head designs, reducing the risk of deformation in composite or plastic suspension arms. The 6mm length is optimised for FTX's suspension geometry, ensuring proper engagement with threaded inserts or through-holes without bottoming out or creating binding. These screws maintain consistent holding power through repeated impact events, vibration cycles, and thermal stress that occur during intense RC racing or bashing sessions. The standard configuration means these parts are immediately recognisable and compatible across multiple FTX Outback model generations, making them an intelligent choice for anyone building a spares inventory for their RC vehicle collection.

Frequently Asked Questions

• What are kingpin screws and why do they matter in RC vehicles? — Kingpin screws are the fasteners that secure the kingpin itself, which is the main pivot point in your RC suspension system. This is where the steering linkage connects to the upright or knuckle, making kingpin fastening absolutely critical for steering geometry, suspension alignment, and overall handling performance. A loose kingpin screw will cause unpredictable steering response, excessive play in the front end, and potential loss of vehicle control during driving.
• Are these screws compatible with all FTX Outback models? — These screws are designed as standard kingpin fasteners for the FTX Outback range, making them compatible with multiple Outback versions and generations. However, always verify your specific model number against the product specifications before ordering, as some older or variant models may use different fastener configurations.
• What is the difference between button head and socket head cap screws? — Button head screws feature a domed top profile that's more compact and aesthetically cleaner than socket head cap screws, whilst delivering equivalent holding power. Button heads are less likely to snag on terrain, vegetation, or chassis components during aggressive RC driving. Socket head cap screws have a higher profile dome and slightly larger contact area, but button heads are often preferred for RC applications where weight and clearance matter.
• How often should I replace kingpin screws? — In normal recreational RC use, kingpin screws rarely require replacement unless they become damaged, stripped, or lost during a crash or maintenance session. However, competitive racers running multiple heat cycles often carry spares to replace fasteners showing any sign of loosening or corrosion. Inspect your kingpin screws regularly for thread damage or deformation, and replace them if you notice any issues affecting secure fastening.
• Can I use these screws as general replacement fasteners for other FTX parts? — Whilst these screws are M3*6 dimension, they are specifically engineered and selected for kingpin applications in FTX Outback vehicles. Other M3*6 screws may technically fit the hole, but using non-approved fasteners could compromise the precise suspension geometry and steering performance your RC vehicle requires. Always use genuine FTX parts for critical suspension fastening to maintain your vehicle's engineering integrity.
• Is this a suitable spare part for beginners? — Yes, absolutely. If you're new to RC and own an FTX Outback, having a pack of spare kingpin screws is one of the most practical and sensible spares you can carry. Beginners often experience crashes and may accidentally damage fasteners during maintenance or repairs, making spare screws invaluable for keeping your RC vehicle operational without waiting for delivery on replacement parts.
