Overview
These ARRMA Button Head Screws in M4x43mm size are essential spare parts for maintaining and servicing your RC vehicle. Whether you own an ARRMA 1/5 scale brushless speed truck like the KRATON 8S or a high-performance stunt truck such as the OUTCAST 8S, having quality replacement hardware is crucial for keeping your RC car UK-ready and race-prepared. The pack contains four precision-engineered screws, ensuring you always have spares on hand when undertaking routine maintenance or repairs on your ARRMA RC models.
Button head screws are the preferred fastening solution for RC hobbyists across the UK who demand reliability and professional results. Unlike standard hex head fasteners, button head screws provide a more streamlined appearance and lower profile, making them ideal for applications where clearance is important. These screws are manufactured to the highest standards, delivering the consistency and durability that ARRMA vehicles are known for. Whether you're a competitive racer, a weekend basher enjoying your brushless RC truck, or an enthusiast performing regular maintenance, these button head screws are an indispensable addition to your spare parts collection.
RC car maintenance is a fundamental part of the hobby, and having the correct replacement parts ensures your vehicle performs at its best. The M4x43mm specification makes these screws compatible with multiple ARRMA models across their 1/5 scale range, from the lightning-fast KRATON 8S 4X4 RTR Brushless Speed Truck to the gravity-defying OUTCAST 8S AVC 4X4 RTR Brushless Stunt Truck. Keep your RC vehicle in top condition with these authentic ARRMA hardware components.
Key Features
- Strong Steel Material — These button head screws are constructed from high-quality steel that provides exceptional durability and longevity, ensuring they won't strip or break during normal use and will maintain a consistent fit every time you fasten them.
- Precision Manufactured Threads — The threads are precision-engineered to exacting tolerances, guaranteeing fast and easy assembly or disassembly during maintenance and repairs without cross-threading or damage to the fastening points.
- Pack of Four Spares — You receive four screws in each pack, which is ideal for keeping spare fasteners readily available so you're never caught without the correct hardware when servicing your ARRMA RC vehicle.
- M4x43mm Specification — The M4 diameter and 43mm length combination is specifically designed for ARRMA applications, ensuring perfect fitment and compatibility across multiple models in the ARRMA 1/5 scale range.
- Low Profile Button Head Design — The button head configuration provides a streamlined, compact profile that minimises protrusion, making these screws ideal for applications where space is limited or where a cleaner appearance is desired on your RC car.
Technical Performance
These ARRMA Button Head Screws represent the engineering excellence that defines the ARRMA brand. Manufactured from strong steel with precision-cut threads, they deliver the reliability and consistency demanded by UK RC enthusiasts who maintain brushless RC vehicles like the KRATON 8S EXB 4X4 Roller and OUTCAST 8S EXB AVC 4X4 RTR models. The M4x43mm dimensions are carefully specified to interface perfectly with mounting points across ARRMA's 1/5 scale vehicle range. The button head design offers distinct advantages over traditional hex head fasteners, including a lower profile that reduces the risk of snags or contact with surrounding components during high-speed operation or extreme stunting. The precision threading ensures that assembly and disassembly during routine maintenance are straightforward and efficient, minimising the risk of thread damage that could compromise future repairs. Whether you're performing suspension adjustments, replacing worn components, or conducting regular service on your 8S brushless electric RC truck, these screws provide the same level of quality and durability that ARRMA's engineers demand throughout their vehicles.

Frequently Asked Questions
- Are these button head screws compatible with my ARRMA RC vehicle? — These M4x43mm button head screws are listed as standard parts for multiple ARRMA 1/5 scale models including the KRATON 8S 4X4 RTR, KRATON 8S EXB, KRATON 8S EXB AVC, OUTCAST 8S AVC, OUTCAST 8S EXB, and their variants. Check your vehicle's parts list or contact us to confirm fitment with your specific model.
- How often should I replace these screws on my RC car? — Button head screws generally have an excellent lifespan when properly maintained. You should inspect them regularly for signs of wear, corrosion, or thread damage. Replace them if you notice stripping, deformation, or difficulty fastening. Having spare packs on hand is ideal for competitive racing or frequent bashing sessions.
- What makes button head screws better than hex head screws? — Button head screws offer a lower, more streamlined profile compared to traditional hex head fasteners, which reduces the overall height of the fastening point. This is particularly beneficial in RC applications where clearance is tight or where you want to minimise protrusion that could catch on obstacles during bashing or racing.
- Can I use these screws on other RC brands besides ARRMA? — Whilst these screws are specifically designed for ARRMA vehicles, the M4x43mm specification is a standard metric size. However, fitment compatibility depends on the specific mounting point design of your vehicle. Always verify that the dimensions and thread pattern match your application before using these screws on non-ARRMA models.
- Why do I need spare button head screws? — During regular maintenance, cleaning, and repairs of your ARRMA RC vehicle, fasteners can become damaged, stripped, or lost. Keeping spare packs of the correct screws ensures you can complete your maintenance without delays and can replace damaged hardware immediately, keeping your vehicle in race-ready condition.
