Overview
The ARRMA Button Head Screw 4x14mm (4) is an essential replacement hardware component designed for RC enthusiasts who maintain and service their high-performance RC vehicles. Whether you're running an ARRMA 1/10 brushless RC monster truck, a competitive 1/8 RC buggy, or any of the wide range of ARRMA models in the UK RC market, having quality replacement screws on hand is crucial for keeping your model in peak condition. These precision-engineered fasteners are manufactured to exacting standards and provide the reliability you need when rebuilding assemblies, performing maintenance, or customising your RC car setup.
Button head screws are a popular choice among RC builders and hobbyists because their distinctive low-profile, rounded head design sits flush with surfaces and reduces the risk of snagging on body panels or components. The M4 x 14mm specification makes these screws compatible with a vast range of ARRMA RC vehicles, from entry-level ready-to-run models to competition-grade builds. For anyone serious about RC hobbies in the UK, maintaining a supply of OEM replacement hardware ensures you can quickly get back to the track, trail, or bash field without unnecessary downtime.
This pack contains four individual screws, making it ideal for replacing worn fasteners, upgrading from standard hardware to premium alternatives, or stocking your RC workshop with genuine ARRMA parts. The strong steel construction and precision-manufactured threads ensure consistent performance and reliable assembly every time you need to service your RC machine.

Technical Performance
The ARRMA Button Head Screw 4x14mm represents the kind of precision hardware that separates professional RC builders from casual hobbyists. Manufactured to metric specifications, the M4 x 14mm dimensions provide the perfect balance between grip diameter and fastening length for countless ARRMA RC applications. The button head design, combined with hex socket drive, allows for efficient assembly and disassembly using standard hex keys whilst minimising the footprint of the fastener head — a critical consideration when working in confined spaces or near suspension geometry. The strong steel construction is specifically chosen to resist stripping, corrosion, and the fatigue stresses that accumulate through repeated RC driving sessions, whether you're running a brushless 1/8 RC buggy like the TYPHON at high speed, a powerful 1/10 brushless monster truck like the BIG ROCK or GRANITE, or a stadium truck variant like the SENTON. These screws are precision-manufactured to deliver consistent thread engagement, meaning you won't experience the frustration of stripped threads or loose fasteners that can ruin a driving session. The black finish provides corrosion resistance and a professional appearance that matches OEM ARRMA components. UK RC enthusiasts appreciate the reliability of genuine manufacturer hardware, and these screws deliver exactly that — no compromise, no frustration, just dependable fastening performance.
