Overview

The ARRMA Cap Head Screw M2.5x20mm (10) Z-ARA723463 is an essential replacement hardware component for RC car enthusiasts and serious bashers across the UK. Whether you're maintaining your ARRMA RC vehicle, performing routine servicing, or rebuilding after a hard day at the track, these precision-manufactured cap head screws are the genuine OEM parts you need to keep your model running at peak performance. ARRMA is renowned for producing high-quality RC cars and trucks, from entry-level ready-to-run models to competition-grade builds, and these fasteners are engineered to the same exacting standards as the vehicles themselves.

If you own an ARRMA 1/8 monster truck, 1/10 buggy, short course truck, or any other model in the ARRMA range, you'll appreciate the importance of using genuine replacement parts. Over time, fasteners can wear, strip, or become lost during maintenance and repair work. Having a supply of high-quality cap head screws means you can get back on the track faster without compromising on build integrity or performance. These screws are designed to work seamlessly with ARRMA suspension components, chassis parts, and body mounts, ensuring perfect fit and reliable assembly every single time.

Key Features

• Strong and Durable Steel Construction — These cap head screws are manufactured from high-quality steel that provides exceptional strength and longevity, ensuring they won't strip, bend, or break under the demanding conditions of RC driving and track use.
• Precision Manufactured Threads — Every screw features precision-engineered threads that provide a consistent, reliable fit into ARRMA chassis and suspension components, eliminating the frustration of loose or poorly fitting fasteners.
• Black Finish — The professional black colour matches standard ARRMA hardware and offers a clean, finished appearance across your RC vehicle.
• M2.5 x 20mm Specification — Designed specifically for ARRMA models, these screws feature the exact dimensions required for chassis mounts, suspension arms, and body attachments.
• Hex Head Driver Type — The cap head design with hex socket (Allen key) drive provides excellent grip and torque application, preventing slippage and cam-out when tightening or loosening.
• Machine Thread Design — The machine threading profile ensures smooth, rapid assembly and disassembly during maintenance and part replacement, making servicing quicker and easier.
• Pack of 10 — This convenient multi-pack gives you plenty of spares for multiple repairs, upgrades, or building replacement parts without needing to order repeatedly.
• Genuine ARRMA OEM Part — As official manufacturer parts, these screws are guaranteed compatible with all ARRMA models and meet factory specifications for fit and performance.

Technical Performance

The M2.5x20mm cap head screw is a fundamental fastening component used throughout ARRMA RC vehicles. With a 2.5mm diameter and 20mm length, these screws are sized perfectly for medium-load applications on 1/10 scale and 1/8 scale RC buggies, short course trucks, and monster trucks. The cap head design provides superior strength compared to flat head or pan head alternatives, whilst the hex socket drive allows for precise torque application without stripping the head. The machine thread profile ensures that repeated assembly and disassembly—essential for regular maintenance and upgrades—won't cause thread damage or loosening. The steel construction provides excellent corrosion resistance compared to cheaper alternatives, meaning your hardware will remain functional even after use in damp conditions or exposure to muddy terrain. Whether you're replacing worn fasteners, building a new suspension arm setup, or assembling custom chassis modifications, these genuine ARRMA screws deliver the reliability and durability you expect from a professional RC manufacturer.

Frequently Asked Questions

• Which ARRMA RC models use M2.5x20mm cap head screws? — These screws are commonly used across ARRMA's range including monster trucks, buggies, short course trucks, and stadium trucks. Check your vehicle's manual or parts diagram to confirm compatibility before ordering, or contact our team for specific model guidance.
• Why should I use genuine ARRMA fasteners instead of generic hardware store screws? — Genuine OEM parts are manufactured to exact factory specifications, ensuring perfect fit, correct thread pitch, and material composition. Generic alternatives may have slightly different dimensions, inferior steel quality, or thread profiles that don't match your ARRMA components, potentially leading to loose connections, damage, or performance issues.
• How many screws come in this pack? — This pack contains 10 individual M2.5x20mm cap head screws, providing enough spares for multiple repairs or chassis modifications without needing to reorder immediately.
• What type of tool do I need to install these screws? — These cap head screws feature a hex socket drive, meaning you'll need a hex key (Allen key) of the appropriate size. ARRMA tool kits or multi-tool sets typically include the correct sizes needed for assembly and maintenance.
• Are these screws suitable for beginners building their first RC car? — Absolutely. If you're assembling an ARRMA RTR (ready-to-run) model and need to replace fasteners, or if you're building from a kit, these genuine screws are essential. Using OEM parts ensures proper assembly and helps your model run reliably from the start.
• How do these cap head screws differ from other fastener types? — Cap head screws offer superior load-bearing capacity and strength compared to flat head or pan head screws due to their domed top design. The hex socket drive prevents slippage and cam-out, making them ideal for applications requiring precise torque. Machine threading allows for smooth, repeatable assembly and disassembly during maintenance.
• Can I use these screws to upgrade other RC brands? — Whilst the M2.5x20mm size is a common metric fastener, we recommend using them only for ARRMA models as specified. Other brands may use different thread pitches or specifications that could cause compatibility issues.
