For RC modellers in the UK and beyond, having quality fasteners in various sizes ensures that repairs and upgrades can be completed quickly without compromising on quality or safety.
Key Features
- 5-40 Thread Size — These screws feature a 5-40 machine thread, which is a standard sizing convention in the RC hobby that ensures compatibility with Losi components and other precision RC parts that utilise this specification.
- 1/2 Inch Length — The 1/2 inch length is ideal for securing lighter components, electronics mounting plates, body clips, and other applications where a shorter fastener is required without sacrificing holding power.
- Flat Head Design — The countersunk flat head profile allows these screws to mount flush with surfaces, creating a clean appearance and preventing snagging on body panels or other components whilst maintaining a professional appearance on your RC vehicle.
- Hex Head Driver — The hex head driver provides positive engagement with standard hex key tools, reducing the risk of stripping compared to other driver types and making installation quick and reliable.
- Machine Thread Construction — These are machine thread screws rather than wood screws, meaning they are designed to work with threaded inserts or pre-tapped holes, typical in precision RC engineering where consistent hole specifications are essential.
- Pack of 10 — This convenient 10-pack gives you multiple spares, ensuring you always have replacements available for repairs, maintenance, or building new RC setups without needing to purchase larger quantities.
- Genuine Losi Component — As official Losi spare parts, these screws are manufactured to the same exacting standards as the original equipment, guaranteeing perfect fit and reliability in your RC car builds and repairs.
Technical Performance
The Losi 5-40 x 1/2 inch Flat Head Screws represent the level of quality and precision engineering that separates professional RC maintenance from casual repairs. Machine thread screws are specifically engineered for use in applications where threaded holes already exist, such as in aluminium chassis plates, servo mounting blocks, or electronics trays commonly found on modern RC buggies and trucks. The 5-40 specification is a metric-compatible sizing standard widely adopted throughout the RC hobby, particularly in 1/10 scale and smaller vehicles where compact, lightweight fasteners are essential. The flat head or countersunk design ensures these screws sit flush with mounting surfaces, which is particularly important in aerodynamic applications where protruding fasteners can create unwanted drag or cause interference with body panels during collisions or rough terrain driving. The hex head driver provides superior grip compared to slotted or Phillips head alternatives, making installation and removal significantly easier whether you are working in a dedicated RC workshop or in the field at a racing event. These screws are ideal for securing electronics enclosures, body retention clips, servo mounts, suspension components, and countless other applications across the Losi range of RC cars and trucks. For anyone serious about maintaining their RC vehicle to the highest standard, stocking genuine replacement fasteners ensures that repairs can be completed without compromise, maintaining both the structural integrity and the aesthetic appearance of your carefully built machine.

Frequently Asked Questions
- What size hole do I need for 5-40 flat head screws? — The 5-40 specification indicates a standard machine thread size commonly used in RC vehicles. These screws are designed for use in pre-tapped holes that match the 5-40 specification. You should refer to your Losi vehicle manual or contact the manufacturer if you are unsure about the correct hole size for your specific application.
- Are these screws compatible with all Losi RC vehicles? — These genuine Losi screws are designed to be compatible with Losi vehicles that specify 5-40 x 1/2 inch fasteners. Compatibility varies by model and application, so you should check your vehicle's manual or parts list to confirm these screws are appropriate for your specific RC car or truck.
- What is the difference between flat head and other screw types? — Flat head or countersunk screws mount flush with surfaces, creating a clean, professional appearance and preventing components from snagging. Other screw types like button head cap screws or pan head screws protrude above the surface, which can be useful in some applications but may interfere with body panels or create drag in aerodynamic applications.
- Why choose genuine Losi screws over generic alternatives? — Genuine Losi components are manufactured to exact specifications, ensuring perfect fit and reliability in your Losi vehicles. Generic fasteners may have slight dimensional variations that can affect assembly, performance, or longevity. For serious RC enthusiasts, maintaining authenticity and quality standards is essential for optimal performance and vehicle lifespan.
- How many screws do I need for a typical repair? — The number of screws needed depends on your specific application and which components you are assembling or repairing. This 10-pack provides excellent value with multiple spares, making it suitable for keeping in your RC toolkit for various maintenance and repair tasks. Many RC builders purchase multiple packs to maintain comprehensive spare parts inventory.
