Key Features
- Super-strong steel material — These screws are manufactured from high-quality steel that resists stripping, breaking and corrosion, ensuring long-lasting durability through countless maintenance cycles and runs on the track or off-road course.
- Precision manufactured threads — Every thread is cut to exact specifications, allowing for fast and easy assembly without cross-threading or jamming, which saves valuable time during maintenance and repairs of your RC vehicle.
- Button head design with hex socket — The recessed hex socket accommodates standard hex drivers, providing plenty of grip for efficient fastening without slipping or damaging the screw head, and the button head profile gives a clean, professional appearance to your RC car.
- M3x16mm specification — This size is perfectly proportioned for use on ARRMA RC vehicles, fitting cleanly into designated screw holes without interference or protrusion that could affect aerodynamics or create catching points.
- Machine thread construction — Machine threads on these screws ensure compatibility with tapped holes in ARRMA vehicle chassis and body components, creating secure, reliable fastening that won't strip when properly torqued.
- Bagged in multiples of 10 — Rather than selling individual screws, ARRMA provides these in convenient 10-packs, ensuring you always have spares available without needing to purchase multiple packs for routine maintenance or accidental loss.
- Genuine ARRMA component — As an official ARRMA part (Z-AR721316), you can be confident these screws are engineered to work perfectly with your specific RC model and maintain manufacturer specifications.
Technical Performance
These ARRMA button head screws represent the kind of attention to detail that separates quality RC hardware from inferior alternatives. The M3x16mm dimensions provide the ideal balance between strength and weight, crucial considerations in RC car design where every gram matters and fasteners must withstand significant stress without adding unnecessary mass. The super-strong steel construction means these screws can be torqued securely without fear of stripping, and they resist vibration loosening through extended driving sessions. The precision-manufactured threads ensure that whether you're assembling a brand-new ARRMA 1/16 Mini Kraton 3S or maintaining a well-used 1/5 scale Outcast 4X4 8S BLX EXB brushless stunt truck, the screws will engage smoothly and hold reliably. Black finish provides corrosion resistance and a professional appearance across your RC car UK build. The hex socket design works with standard metric hex keys (size 2.0mm for M3 fasteners), making these screws accessible to anyone with basic RC car tools. Whether you're performing routine maintenance, making suspension adjustments, or reassembling components after repairs, having genuine ARRMA hardware ensures your RC vehicle maintains its original engineering integrity and performance characteristics.

Frequently Asked Questions
- What ARRMA vehicles are these button head screws compatible with? — These M3x16mm button head screws are compatible with multiple ARRMA models including the 1/16 Mini Kraton 3S Red, the 1/16 Mini Kraton 3S in Teal and Blue (with battery and charger included versions), and the 1/5 Outcast 4X4 8S BLX EXB Brushless Stunt Truck RTR in Black. Always check your vehicle's parts diagram to confirm screw placement before installation.
- Are these genuine ARRMA parts? — Yes, the ARRMA Button Head Screw 3x16mm (10) is the official genuine component with part number Z-AR721316, manufactured by ARRMA to their exact specifications. Using genuine components ensures compatibility, reliability and maintains your vehicle's performance and warranty status.
- How many screws do I get in this pack? — This pack contains 10 individual button head hex screws, M3x16mm specification. This quantity is perfect for having spares available for routine maintenance, replacements, or repairs without needing to purchase multiple packs.
- What size hex key do I need? — M3 button head hex screws typically require a 2.0mm hex key (Allen key) for installation and removal. Check your ARRMA instruction manual or parts diagram for the specific tool size recommended for your model.
- Can I use these screws on other RC car brands? — While the M3x16mm dimensions are standard, these screws are engineered specifically for ARRMA vehicles. Using non-genuine parts on other RC car brands may result in compatibility issues. Always use manufacturer-recommended fasteners for your specific ready to run RC vehicle.
- How do I prevent these screws from loosening during driving? — Apply a small amount of thread-locking compound (medium strength, removable type) to the screw threads before installation. This prevents vibration loosening during high-speed driving or jumps while still allowing future removal for maintenance. Do not over-tighten, as this can strip the threads.
