Overview
The Corally Steel Nylstop Nut M4 Black Coated is an essential fastening component for RC enthusiasts across the UK who demand precision engineering and reliability in their builds. Whether you're maintaining a high-performance RC car, buggy, or truck, these hexagon nylstop nuts are engineered to prevent vibration-induced loosening during aggressive driving and competition use. As a dedicated RC car UK retailer, we understand that the smallest components can make the biggest difference in your model's performance and longevity, which is why we stock genuine Corally fasteners that meet OEM specifications.
These premium steel nylstop nuts are black coated for enhanced corrosion resistance and a professional finish that complements modern RC builds. The M4 thread size makes them ideal for suspension components, drive shafts, and structural assemblies on popular 1/10 scale RC vehicles and larger models. Each pack contains 10 individual nuts, providing you with spare fasteners for maintenance, repairs, or complete rebuild projects. The nylon insert within each nut creates a locking feature that maintains bolt tension under vibration and repeated impacts, ensuring your RC model stays assembled during bashful off-road adventures or competitive racing.
For anyone building, modifying, or maintaining RC vehicles in the UK, these Corally fasteners represent outstanding value and engineering quality. The hexagon design allows for quick installation and removal using standard tools, making them perfect for pit maintenance, component upgrades, or emergency repairs during track days. Whether you're a seasoned RC competitor or a weekend basher exploring the RC hobby UK community, having quality nylstop nuts in your spare parts collection is essential for keeping your model race-ready.
Key Features
- M4 Thread Size — These nylstop nuts are specifically engineered for M4 fasteners, making them compatible with a wide range of RC suspension mounts, drive train components, and structural assemblies found on 1/10 scale and larger RC vehicles. The M4 size is one of the most commonly used thread specifications in quality RC models.
- Hexagon Design — The six-sided hexagon profile allows you to grip the nut securely with standard hex tools or wrenches during installation and removal, providing positive engagement and preventing rounding of corners even when working with older or well-used fasteners.
- Steel Construction with Black Coating — These nuts are manufactured from hardened steel and finished with a black coating that provides superior corrosion resistance compared to bare metal fasteners. The black coating also offers a professional, finished appearance that complements modern carbon-fibre and anodised aluminium chassis.
- Nylstop Locking Feature — Each nut incorporates a nylon insert that creates a self-locking mechanism, preventing the fastener from loosening due to vibration during high-speed driving or aggressive off-road use. This is essential for maintaining structural integrity during competitive RC racing and everyday bashful driving.
- Pack of 10 Units — This generous quantity provides you with multiple spare nuts for repairs, replacements, and complete rebuild projects, ensuring you'll always have the correct fasteners on hand when maintaining your RC collection.
- OEM Quality — As Corally genuine fasteners, these nuts meet original equipment manufacturer specifications and are trusted by professional RC teams and everyday enthusiasts alike throughout the UK RC community.
Technical Performance
The Corally Steel Nylstop Nut M4 Black Coated represents the fastening standard expected by discerning RC enthusiasts who refuse to compromise on component quality. Manufactured from hardened steel and finished with a robust black coating, these nuts deliver the performance necessary for demanding applications where vibration and impact forces are constant concerns. The M4 thread specification ensures compatibility with a comprehensive range of RC suspension components, drive shafts, and chassis assemblies found across popular 1/10 scale platforms and larger vehicles. The hexagon profile is precision-engineered to standard industrial specifications, allowing positive engagement with standard metric tools whilst resisting deformation during installation and removal. The nylon insert locking mechanism functions through a slight interference fit created between the threaded core and the nylon insert, creating friction that prevents rotation whilst allowing one-time installation without excessive torque requirements. This design has been proven through decades of industrial and RC applications, delivering superior vibration resistance compared to simple castle nuts or split pins. For RC builders in the UK working on brushless-powered vehicles or high-torque suspension systems, these fasteners provide the engineering assurance needed for consistent performance session after session.

Frequently Asked Questions
- What makes a nylstop nut different from a regular nut? — A nylstop nut incorporates a nylon insert that grips the bolt thread, creating a self-locking mechanism that prevents loosening caused by vibration. This is critical for RC vehicles where constant impacts and vibration during driving can cause regular fasteners to gradually work loose. Unlike castle nuts that require split pins or Loctite threadlocker, nylstop nuts provide permanent vibration resistance without requiring additional components.
- Is the M4 size suitable for my RC car? — M4 fasteners are among the most commonly used thread sizes in quality RC vehicles, particularly on 1/10 scale buggies, trucks, and on-road racers. M4 nylstop nuts are typically used for suspension mounting points, drive shaft assemblies, and structural chassis connections. Check your RC model's manual or examine existing fasteners to confirm M4 compatibility before ordering.
- Why is the black coating important? — The black coating provides enhanced corrosion resistance, protecting the steel underneath from rust and oxidation when exposed to moisture during wet-weather RC driving or outdoor storage. The black finish also delivers a professional appearance that complements modern carbon-fibre chassis and anodised aluminium components commonly found on contemporary RC models.
- Can I reuse nylstop nuts after removal? — Yes, nylstop nuts can typically be reused several times before the nylon insert becomes worn and loses its locking effectiveness. However, for critical suspension and drive components, many RC teams replace them with fresh nuts periodically to ensure maximum vibration resistance and structural security.
- How many nuts will I need? — This depends on your specific RC model and intended use. A typical 1/10 scale RC buggy might use 20-30 M4 fasteners across suspension, drive train, and chassis assemblies. The pack of 10 is ideal for spare parts storage, component upgrades, or builds where you need reliable fasteners for critical connections. Many experienced RC builders keep multiple packs in their workshop for reliability.
- Are these genuine Corally parts? — Yes, these are genuine Team Corally fasteners manufactured to OEM specifications and sold through authorised RC retailers across the UK. Genuine Corally fasteners ensure compatibility with your RC model and deliver the quality engineering you expect from this respected brand.
