Overview
The ARRMA Flat Head Hex Machine Screw M3.5x16mm (10) Z-ARA703016 is an essential replacement and upgrade component for RC enthusiasts across the UK who demand reliability and precision in their builds. Whether you're maintaining your existing ARRMA RC car, repairing damaged fasteners, or upgrading your vehicle for enhanced performance, these quality machine screws offer the durability and consistency that serious RC hobbyists expect. As a trusted authorised ARRMA dealer, RC Model Shop stocks this genuine component to ensure your RC vehicles remain in peak condition.
These flat head hex machine screws are engineered to exacting standards and represent the same quality components found in factory-built ARRMA RC models. For anyone running an ARRMA 1/5 Outcast 4X4 8S BLX or other compatible models, having spare fasteners on hand is essential for maintenance, repairs, and performance tuning. The pack of 10 screws ensures you have adequate spares for multiple repair jobs or projects, making this an affordable and practical investment for your RC hobby setup.
Machine screws like these are fundamental to RC car maintenance and building. Unlike standard screws, hex machine screws feature a hexagonal socket drive that allows for precise, secure fastening without cam-out or stripping, which is particularly important when working with aluminium and composite materials commonly found in high-performance RC vehicles. Whether you're a weekend basher enjoying off-road RC adventures or a serious competitor preparing your RC car for the track, quality fasteners are non-negotiable.
Key Features
- Genuine ARRMA Component — These are authentic ARRMA-manufactured screws, ensuring perfect compatibility with your RC car and guaranteed performance that matches factory specifications. Using genuine parts protects your investment and maintains the integrity of your vehicle.
- M3.5x16mm Specifications — The M3.5 diameter and 16mm length make these screws ideal for a wide range of assembly and repair applications on ARRMA RC models, providing versatility for multiple mounting points and fastening tasks throughout your vehicle.
- Hex Socket Drive — The hexagonal socket design prevents stripping and cam-out, which can occur with conventional Phillips or slotted fasteners, especially when working under pressure or using power tools on your RC car components.
- Machine Thread Construction — These screws feature machine thread design, which provides superior holding power and consistent engagement compared to wood screws or other fastener types, ensuring your components stay secure during intense racing or bashing sessions.
- Countersunk Flat Head Design — The flat head configuration sits flush with the mounting surface, reducing protrusions that could catch on obstacles or create aerodynamic drag on your RC vehicle, whilst maintaining a clean, professional appearance on your RC car.
- Steel Construction — Manufactured from durable steel, these fasteners offer excellent strength-to-weight ratio and corrosion resistance, particularly important if your RC car sees wet terrain or long-term storage between use.
- Pack of 10 Units — This generous quantity ensures you have multiple spares for repairs, maintenance, or building projects, eliminating the frustration of running out of fasteners mid-build when working on your RC car UK setup.
- Confirmed Compatible with ARRMA 1/5 Outcast 4X4 8S BLX — These screws are specifically designed to fit and function with the ARRMA Outcast 4X4 8S BLX EXB, a powerful brushless stunt truck, though their M3.5x16mm dimensions make them suitable for numerous other RC applications and vehicle types.
Technical Performance
The ARRMA Flat Head Hex Machine Screw M3.5x16mm represents precision fastening engineering designed specifically for the demands of modern RC hobby applications. Machine thread screws like these are engineered differently from conventional fasteners, featuring precisely cut threads that create consistent engagement depth and prevent the stripping issues that plague cheaper fasteners. The M3.5 diameter provides an ideal balance between holding strength and clearance, allowing designers to pack more components into tight spaces without sacrificing structural integrity. The 16mm length specification places these screws in the ideal range for mounting brackets, servo horns, damper towers, and suspension components common to ARRMA RC vehicles. Steel construction provides exceptional durability whilst remaining lightweight enough not to negatively impact your RC car's weight distribution or handling characteristics. The countersunk flat head design is particularly important for RC applications where components must sit flush with mounting surfaces to maintain proper geometry and avoid snagging during high-speed running or aggressive terrain interaction. The hex socket drive offers significant advantages over conventional fastener designs: it provides superior grip engagement, reduces the risk of bit slip and fastener damage, allows for faster installation using power tools or hex key wrenches, and prevents the cosmetic damage that Phillips screws often sustain during assembly. For anyone building, rebuilding, or maintaining RC cars and trucks in the UK market, having a supply of quality machine screws is as essential as having the right lubricants and maintenance fluids. These ARRMA-genuine components ensure your RC vehicle maintains factory-level assembly standards and performance characteristics.

Frequently Asked Questions
- What is a hex machine screw and how does it differ from other fasteners for RC cars? — Machine screws feature pre-cut, consistent threading designed to create uniform engagement in threaded holes, unlike wood screws which cut their own threads. The hexagonal socket provides superior grip compared to Phillips or slotted heads, preventing the bit slip and fastener damage that commonly occurs when working on RC cars. Machine screws maintain their integrity through repeated assembly and disassembly, making them ideal for RC maintenance and building work.
- Will these screws fit my ARRMA RC car? — These screws are confirmed compatible with the ARRMA 1/5 Outcast 4X4 8S BLX EXB Brushless Stunt Truck RTR. However, the M3.5x16mm dimensions are standard specifications found across numerous ARRMA models and other RC manufacturers' products. Before ordering, verify that your specific RC vehicle uses M3.5 fasteners and requires 16mm length screws at the mounting points you intend to service.
- How many screws should I buy for my RC car? — This pack contains 10 screws, which is suitable for a single comprehensive maintenance or rebuild session on a typical RC car. Given that fasteners can be lost during transport, damage during assembly, or consumed by multiple projects, many experienced RC enthusiasts in the UK maintain multiple packs of common sizes like M3.5x16mm. For serious competitors or those maintaining multiple RC vehicles, having two or three packs ensures you're never without spares.
- Are these genuine ARRMA parts? — Yes, these are authentic ARRMA-manufactured components supplied through authorised retailers like RC Model Shop. Genuine ARRMA fasteners guarantee compatibility, consistent quality, and specifications matching your vehicle's original assembly standards. Counterfeit or generic fasteners may appear cheaper but often feature inconsistent threading, poor material quality, and reduced holding strength, risking your RC investment.
- Can I use these screws with power tools or do I need to hand-tighten? — The hex socket design makes these screws compatible with both hand-operated hex keys and power tool drivers, allowing faster assembly work. However, experienced RC builders recommend controlled installation, particularly when working with plastic or composite materials, to avoid over-torquing and damaging threads or mounting points on your RC car.
- What makes flat head screws better than other head styles for RC applications? — Flat head (countersunk) screws sit flush with the mounting surface, eliminating protrusions that could catch terrain obstacles, reduce aerodynamics, or interfere with other components on your RC vehicle. This flush fit is particularly important on exposed mounting points on RC cars and trucks used for bashing or racing.
