Overview

The ARRMA Button Head Hex Machine Screw 3x3mm (10) Z-AR721303 is an essential replacement part for RC enthusiasts and serious hobbyists across the UK. Whether you're maintaining your RC car, RC truck, or any ARRMA model, these precision-engineered fasteners are designed to keep your machine running smoothly and reliably. ARRMA is a globally recognised manufacturer of high-performance RC vehicles, and their spare parts are engineered to the same exacting standards as their complete models. These button head screws are ideal for anyone who operates RC cars UK-wide, from casual weekend bashers to competitive racers who demand the highest quality components.

Fasteners might seem like small details, but they're absolutely critical to the performance and longevity of your RC hobby setup. Stripped screws, loose connections, and poor-quality threads can lead to mechanical failures, lost races, and frustrating downtime. This is why ARRMA manufactures their own screws rather than relying on generic alternatives. The button head hex machine screw is one of the most commonly used fasteners in RC vehicle assembly and maintenance, making this 10-pack an excellent addition to any spare parts collection. Whether you're rebuilding a damaged component, customising your setup, or simply restocking your maintenance kit, these screws represent genuine OEM parts that will fit perfectly and perform reliably.

RC model enthusiasts in the UK know that proper maintenance is the foundation of long-term enjoyment and competitive success. Having genuine ARRMA replacement parts on hand means you can perform quick repairs and upgrades without waiting for delivery times or compromising on quality. This pack of 10 button head screws covers multiple repair scenarios and ensures you're never caught short during a servicing session.

Key Features

  • Strong and durable steel construction — These button head 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 vehicles that undergo frequent maintenance and adjustment.
  • Precision manufactured threads — The machine threads are produced to exacting tolerances, ensuring a consistent and secure fit every time you use them, which eliminates the frustration of loose screws or cross-threaded fasteners that can damage expensive RC components.
  • Button head design — The rounded button-style head provides a low-profile appearance while offering excellent grip for hex key tools, making them ideal for tight spaces and allowing for quick engagement without the risk of slipping or stripping the head.
  • M3 x 3mm specification — These screws are sized at M3 (metric 3mm diameter) with a 3mm length, making them perfect for precise assembly work on smaller components where compact fastening is required.
  • Hex socket driver — The hex socket design means you can use standard Allen keys or hex drivers, which are tools every RC enthusiast already owns and keeps in their maintenance kit.
  • Pack of 10 — One pack provides enough screws to complete multiple repairs or full component rebuilds, reducing the number of orders you need to place and keeping your spare parts drawer well-stocked.
  • Genuine OEM part — These are official ARRMA parts designed specifically for ARRMA vehicles, guaranteeing compatibility and performance with your equipment.

Technical Performance

The ARRMA Button Head Hex Machine Screw 3x3mm represents the kind of precision engineering that separates professional-grade RC components from budget alternatives. Manufactured from hardened steel with carefully controlled thread specifications, these screws are designed to withstand the vibration, impact, and thermal stress that RC vehicles experience during operation. The M3 diameter is the standard size for countless fastening applications across RC buggies, trucks, and crawlers, making this a genuinely versatile spare part. The 3mm length is specifically engineered to fasten components without protruding excessively, which is important in tightly packed RC chassis and body panels where space is at a premium. The button head design provides a low-profile appearance while the hex socket ensures positive engagement with your driver tool, eliminating the wobble and potential damage that can occur with phillips or slot-head screws. The precision machined threads ensure that every insertion and removal cycle maintains thread integrity, which is critical for RC vehicles that undergo regular disassembly for cleaning, upgrade, and repair. Black finish prevents corrosion and maintains the aesthetic appearance of your machine. These are the exact same screws supplied in ARRMA factory kits, meaning you're getting components trusted by the manufacturer itself.

Frequently Asked Questions

  • What ARRMA models are these screws compatible with? — These button head hex machine screws are compatible with the Arrma 1/10 QUAKE 223S DSC 2WD RTR Brushless Monster Truck series, available in Red, Purple, and Green variants. However, due to their standard M3 x 3mm specification, they're also suitable for numerous other ARRMA models and many RC vehicles from other manufacturers that use metric fasteners of this size.
  • Are these genuine ARRMA parts or aftermarket replacements? — These are genuine OEM ARRMA parts, manufactured by ARRMA specifically for use in their vehicles. This ensures perfect compatibility, quality assurance, and performance. Choosing genuine parts over generic fasteners is always recommended for mission-critical components like screws that hold major assemblies together.
  • Why would I need replacement screws for my RC car? — RC vehicles undergo regular assembly and disassembly during maintenance, cleaning, upgrades, and repairs. Over time, fasteners can become stripped, lost, or damaged through normal use. Having genuine replacement screws ensures you can always complete any maintenance task without compromising quality or fit.
  • Will these fit other RC brands besides ARRMA? — The M3 x 3mm metric specification is a standard size used across the RC industry, so these screws may fit other brands that use metric fasteners. However, we always recommend using genuine parts specified for your particular model to ensure perfect compatibility and warranty protection.
  • How many screws come in a pack? — Each pack contains 10 button head hex machine screws, providing enough fasteners for multiple component repairs or complete rebuilds of smaller assemblies.
  • What tools do I need to install these screws? — You'll need a standard hex Allen key tool (also called a hex driver or hex bit) that matches the socket size. These tools are inexpensive and are included with most RC toolkit sets.
