- 5/8 Inch Length — The specific length is precisely engineered for Losi component applications, ensuring proper fastening depth without bottoming out or creating excessive protrusion that could affect component fit or clearance.
- Pack of Six — With six screws included, you have multiple spares available for different maintenance tasks, allowing you to keep extra fasteners in your RC spares collection for convenience and peace of mind.

Technical Performance
The Losi 4-40 x 5/8 inch Flat Head Screws represent the precision engineering standards that Losi applies to all their replacement fasteners. The 4-40 thread designation refers to a #4 screw with 40 threads per inch, a standard specification widely used in precision RC applications where fine-threaded fasteners are required for secure, vibration-resistant assembly. The 5/8 inch length is precisely calculated to provide adequate engagement depth in Losi components whilst maintaining proper clearance and avoiding over-tightening issues. Flat head (countersunk) screws are specifically engineered to sit flush with mounting surfaces, which is critical for RC applications where aerodynamics and body fit are important considerations. The fastener material is engineered for durability and corrosion resistance, essential properties for fasteners that must withstand the stress of RC racing, outdoor use, and exposure to moisture from wet terrain. Whether you're reassembling a Losi buggy after a major maintenance session, replacing fasteners that have vibrated loose during high-speed running, or building up spare component assemblies, these screws deliver the reliability and precision fit that serious RC enthusiasts demand. The pack of six provides practical value, allowing you to maintain a stock of replacement fasteners without excessive cost.

Frequently Asked Questions
- What are flat head screws used for in RC cars? — Flat head (countersunk) screws are used in applications where a flush finish is required, such as mounting body panels, securing electronics enclosures, attaching trim pieces, and fastening components where protruding screw heads would interfere with fit or aerodynamics. The countersunk design allows the screw head to sit level with the mounting surface.
- Will these screws fit my Losi RC vehicle? — Yes, these genuine Losi OEM fasteners are manufactured to precise specifications for Losi RC vehicles. The 4-40 x 5/8 inch size is a standard specification used across many Losi models and components. However, you should verify the specific requirement for your particular model before ordering, as different Losi vehicles may use different fastener sizes.
- How many screws should I order? — This pack contains six screws, which is useful for multiple repair or maintenance tasks. Many RC enthusiasts keep several packs in their spares box, as fasteners are easily lost or damaged during field use and maintenance work.
- Are these screws compatible with other RC brands? — While the 4-40 x 5/8 inch specification is a standard fastener size that may fit other RC vehicles, these are genuine Losi parts specifically engineered for Losi vehicles. For compatibility with other brands, you should verify the fastener specification in your vehicle's documentation.
- What is the difference between flat head and button head screws? — Flat head screws (countersunk) sit flush with the mounting surface when properly installed, providing a smooth, aerodynamic finish ideal for body panels and exposed components. Button head screws have a rounded head that protrudes above the mounting surface, making them easier to grip with tools but less suitable for applications requiring a smooth finish.
