Overview
The Losi 5-40 x 1/2 inch Button Head Screws (8) Z-LOSA6278 are precision fasteners manufactured by Losi, one of the most respected names in RC car and RC truck engineering. These button head screws are an essential component for RC enthusiasts who maintain, repair, and upgrade their RC vehicles. Whether you own a Losi RC buggy, RC rock crawler, or any other RC model that uses 5-40 threading, having quality replacement screws on hand is crucial for keeping your RC car UK-ready and performing at its best.
Button head screws are a favourite among RC hobbyists because they offer a lower profile than traditional socket head screws, making them ideal for applications where clearance is tight or where you want a cleaner aesthetic on your RC vehicle. These Losi screws come in a pack of eight, providing excellent value for spare parts. Whether you are a competitive racer, a weekend basher, or someone who simply enjoys maintaining their RC collection, these fasteners will prove invaluable in your hobby toolkit.
RC enthusiasts know that the smallest components often make the biggest difference in reliability and performance. The Losi 5-40 x 1/2 inch Button Head Screws are manufactured to the exacting standards you would expect from Losi, ensuring they work perfectly with your RC car or truck components and deliver the durability needed for serious RC play.
Key Features
- Button Head Design — The button head profile sits lower and more flush than standard socket head screws, making them perfect for RC applications where space is limited or where you want a refined, professional appearance on your RC model.
- 5-40 Thread Size — These screws use the 5-40 thread specification, which is a common fastening size across many Losi RC vehicles and components, ensuring compatibility with your existing setup.
- 1/2 Inch Length — The 1/2 inch length is ideal for securing lightweight RC components and parts, providing the right penetration depth without being too long for delicate RC assemblies.
- Machine Thread Type — The machine thread configuration means these screws work with pre-drilled or threaded holes, allowing for quick and secure assembly without damaging surrounding RC components.
- Hex Driver Type — The hex driver type makes installation and removal quick and easy with a standard hex key or driver, a tool every RC modeller should have in their workshop.
- Silver Colour Finish — The silver finish gives your RC model a polished, professional look whilst providing corrosion resistance for outdoor RC bashing and racing.
- Pack of Eight Screws — Eight screws per pack means you have spares for multiple applications or future repairs, reducing downtime on your RC car UK adventures.
- Genuine Losi Component — As official Losi fasteners, these screws are engineered to the same high standards as every other Losi component, guaranteeing fit, finish and reliability.
Technical Performance
The Losi 5-40 x 1/2 inch Button Head Screws represent the kind of precision engineering that separates quality RC components from budget alternatives. Manufactured from durable materials with a silver finish, these screws provide excellent corrosion resistance, making them suitable for both indoor track racing and outdoor RC bashers who face variable weather conditions. The button head design is particularly advantageous for RC vehicles where every millimetre of clearance matters. The 5-40 thread specification is a metric-compatible fastening standard widely used across the Losi RC product range, from 1/10 scale rock crawlers to 1/8 scale buggies and beyond. The hex driver type ensures that you can use any standard hex key from your RC toolkit, and the machine thread design means these screws integrate seamlessly with Losi's pre-drilled and threaded holes. The 1/2 inch length provides optimal grip length for typical RC component applications without excessive protrusion. Whether you are reassembling your RC car UK after maintenance, replacing stripped fasteners, or building up a new RC model from the ground up, these screws deliver the reliability and consistency that serious RC enthusiasts demand.

Frequently Asked Questions
- What are button head screws used for in RC models? — Button head screws are used throughout RC vehicles for securing components like suspension arms, servo mounts, shock towers and body panels. The lower profile design makes them ideal for tight spaces where standard socket head screws would interfere with other components. The Losi 5-40 x 1/2 inch specification is particularly common in Losi's mid-scale RC buggies, crawlers and trucks.
- Are these screws compatible with my Losi RC vehicle? — These 5-40 x 1/2 inch button head screws are designed as Losi components and will be compatible with any Losi RC model that uses 5-40 threading. If you are unsure whether your specific RC vehicle uses this size, consult your RC model's instruction manual or contact RC Model Shop for advice.
- How many screws come in this pack? — Each pack contains eight screws, providing excellent value and ensuring you have spare fasteners for repairs or multiple applications across your RC collection.
- What is the difference between button head and socket head screws? — Button head screws feature a more rounded, lower profile compared to socket head screws, which have a taller, more angular shape. This makes button head screws ideal for RC applications where you need minimal profile and good aesthetic appearance. The button head design also reduces the risk of snagging on nearby components during assembly and disassembly.
- Can I use these for outdoor RC bashing? — Yes, absolutely. The silver finish provides corrosion resistance, making these screws suitable for outdoor use. However, if you regularly use your RC car in wet or extremely corrosive environments, inspect fasteners regularly for any signs of corrosion and replace as needed.
- What tools do I need to install these screws? — You will need a hex key or driver that matches the hex socket in the button head. Most standard RC tool sets include appropriately sized hex drivers, making installation straightforward for any RC enthusiast.
