Overview
The ARRMA Flat Head Screw 4x12mm (4) Z-AR722412 is an essential maintenance component for RC enthusiasts across the UK who own ARRMA vehicles. Whether you're a seasoned competitor running a brushless RC monster truck, or a weekend basher enjoying the latest 1/8 scale RTR models, having quality replacement fasteners in your spares box is crucial for keeping your RC car performing at its best. These high-quality flat head screws are precision-engineered to match the exacting standards ARRMA applies to their complete ready-to-run and kit vehicles, ensuring reliable performance during servicing and repairs.
RC maintenance is an unavoidable part of ownership, particularly when you're regularly running your vehicle across rough terrain or pushing it to its limits on a race track. The ARRMA Flat Head Screw 4x12mm pack contains four individual screws, bagged in practical multiples so you always have spares ready when you need them. This is exactly the kind of consumable that experienced RC hobbyists keep stocked in their workshop, as fasteners can be lost, stripped, or damaged during intensive use. With a customer rating of 3.9 out of 5 on the manufacturer page, these screws have proven themselves as reliable spares across a wide range of ARRMA models.
What sets these screws apart is their commitment to quality and durability. ARRMA has engineered these fasteners specifically for their vehicle range, meaning you can trust them to fit perfectly and perform consistently across every servicing cycle. From the 1/10 scale BIG ROCK and GRANITE monster trucks through to the full range of 1/8 scale buggies, speed trucks and stunt vehicles, right up to the impressive 1/5 and 1/7 scale models, these M4x12mm flat head screws are recognised as standard parts across the ARRMA lineup. If you own any ARRMA RC vehicle, these are the genuine replacement screws you should be using.
Key Features
- Super-strong steel material — Manufactured from premium steel that resists corrosion and maintains its structural integrity through repeated use, ensuring your RC vehicle stays securely fastened during the most demanding driving sessions.
- Precision manufactured threads — Every screw is produced to exacting specifications with carefully formed threads that engage smoothly and reliably, making assembly and disassembly straightforward during routine maintenance and repairs.
- Flat head countersunk design — The countersunk head style sits flush with the mounting surface, reducing aerodynamic drag and maintaining the clean appearance of your RC vehicle whilst providing secure fastening.
- M4x12mm specification — The 4mm diameter and 12mm length are specifically engineered for ARRMA's chassis components, ensuring perfect compatibility without the risk of over-tightening or under-fastening.
- Bagged in convenient multiples — This pack includes 4 screws, giving you immediate spares and the ability to keep additional sets in your spares box for ongoing maintenance and repairs.
- Genuine ARRMA parts — As manufacturer-approved components, these screws are guaranteed to meet the same quality standards as those supplied with new ARRMA vehicles.
Technical Performance
These flat head screws are engineered to the highest standards using super-strong steel construction that provides both durability and corrosion resistance. The M4x12mm sizing represents the standard fastener specification used across numerous ARRMA models, from small-scale 1/10 brushless RC monster trucks and stadium trucks through to the larger 1/5 and 1/7 scale RTR vehicles featuring advanced 6S and 8S brushless powerplants. The precision-manufactured threads are cut to exact tolerances, meaning they will engage smoothly whether you're assembling components during initial setup or performing routine maintenance after intensive use. The countersunk flat head design is particularly important in RC applications, as it prevents the fastener from protruding above the mounting surface, which could otherwise interfere with moving parts, reduce aerodynamic efficiency, or cause the screw to snag on terrain during rough driving. The black finish provides both an aesthetic appeal and protection against corrosion during extended storage or use in damp UK conditions. These screws use a hex driver type, meaning you'll need an appropriately sized hex key for installation and removal—a standard tool in any RC enthusiast's workshop.
