Key Features
- Strong and durable steel construction — The screws are manufactured from high-quality steel that resists stripping and maintains its integrity through repeated assembly and disassembly cycles, which is essential for RC hobbyists who regularly service their vehicles.
- Precision manufactured threads — The precisely cut machine threads ensure a consistent, reliable fit every time, allowing for fast and secure servicing without the frustration of cross-threading or loose fasteners that compromise vehicle performance.
- Flat head countersunk design — The countersunk head profile ensures a flush, professional finish when installed, reducing drag and maintaining the aerodynamic profile of your RC vehicle whilst creating a clean appearance.
- Metric M4 x 16mm specification — These screws are specifically sized at 4mm diameter with 16mm overall length, matching the exact specifications of factory ARRMA components for perfect compatibility and fitment.
- Hex socket driver configuration — The hex socket head allows for secure, precise tightening with an Allen key, providing excellent tool engagement and reducing the risk of stripping the screw head during installation.
- Pack of four screws — Each pack contains four individual screws, giving you spares to keep in your RC toolkit and ensuring you're never caught short during maintenance or repairs.
Technical Performance
These M4 x 16mm flat head hex machine screws are engineered with precision manufacturing techniques that ensure consistent performance across every fastener in the pack. The steel construction provides exceptional strength-to-weight ratio, critical for RC applications where unnecessary weight can impact performance, yet durability cannot be compromised. The precision-cut machine threads offer superior holding power compared to standard fasteners, ensuring that once tightened, your components stay secure even during high-speed runs and aggressive bashings typical of ARRMA vehicles. The countersunk flat head design is particularly important for RC applications where aerodynamic efficiency matters; the flush installation profile eliminates protruding fastener heads that could catch air or create unexpected drag. The hex socket configuration provides a firm, positive engagement with your Allen key, minimising the risk of tool slip or screw head damage that can occur with Phillips or slotted drivers. Whether you're servicing a 1/5 scale speed demon like the KRATON 8S or maintaining one of the precision-engineered 1/7 scale machines such as the FELONY 6S AVC, these screws deliver the reliability that ARRMA is known for. British RC enthusiasts appreciate fasteners that won't fail mid-track or mid-bash, and these screws are engineered to that exact standard.

Frequently Asked Questions
- What ARRMA models are these screws compatible with? — These M4 x 16mm flat head hex machine screws are compatible with a comprehensive range of ARRMA vehicles including the 1/5 KRATON 8S (all variants including the EXB and AVC versions), 1/5 OUTCAST 8S (EXB and AVC models), plus numerous 1/7 scale models including the BIG ROCK 6S, FELONY 6S AVC, FIRETEAM 6S, INFRACTION 6S, LIMITLESS variants, and MOJAVE 6S, as well as several 1/8 scale KRATON, NOTORIOUS, OUTCAST, and TALION models. The extensive fitment list confirms these are genuine ARRMA fasteners designed for their complete product range.
- Are these suitable as replacement parts for maintenance? — Absolutely. These screws are specifically designed as replacement parts for kit-supplied items, making them ideal for routine maintenance, seasonal servicing, or replacing worn fasteners that may have stripped or corroded over extended use. UK hobbyists can confidently use these to restore their ARRMA vehicles to factory specification.
- What makes these better than standard fasteners from a hardware shop? — ARRMA's precision-manufactured machine screws are engineered specifically for RC vehicles, with precision-cut threads that ensure consistent fit and fast, frustration-free servicing. Standard hardware shop fasteners often have looser tolerances and inferior steel quality, resulting in stripped threads and unreliable performance. These genuine ARRMA parts guarantee compatibility and longevity.
- How should I store these screws to prevent corrosion? — Keep them in a dry location within your RC spares box. The steel construction is robust, but storing them in a sealed container away from moisture will maximise their lifespan and prevent any potential surface corrosion over extended periods.
- Can I use these for custom RC builds? — Yes, if you're working with ARRMA components or building custom setups using ARRMA parts, these M4 x 16mm screws can be used wherever this size specification is appropriate. However, always verify compatibility with your specific application before assembly.
