Key Features
- Genuine Losi Specification — These screws are manufactured to Losi's original equipment standards, ensuring perfect compatibility with Losi RC vehicles and components. Using genuine manufacturer parts guarantees reliability and longevity where aftermarket alternatives may compromise performance.
- Button Head Design — The button head profile provides an attractive, low-profile fastening solution that reduces snagging and sits flush with surrounding components. This design is particularly useful in tight spaces and minimises the risk of loose items catching on protruding screw heads during high-speed operation.
- 540 x 1 1/4 Inch Dimensions — The precise 540 diameter with 1 1/4 inch length specification ensures these screws fit exactly where Losi engineers intended them to fit. Correct sizing is critical in RC vehicles where even small mismatches can affect assembly integrity and component alignment.
- Eight-Pack Quantity — This convenient eight-pack provides multiple fasteners for comprehensive repairs, maintenance routines, or as backup spares in your RC toolbox. Having several screws on hand means you're prepared for unexpected breakages or when undertaking jobs requiring multiple fasteners.
- Durable Construction — Manufactured from quality materials appropriate for RC applications, these screws withstand repeated assembly and disassembly cycles, vibration from motor operation, and the environmental stresses typical of RC car use both indoors and outdoors.
Technical Performance
The Losi 540 x 1 1/4 inch BH Screw represents precision fastening engineering designed specifically for the demands of RC vehicles. The button head design minimises profile height whilst maintaining excellent grip and torque resistance, critical characteristics when fastening components in the compact, vibration-prone environment of an RC car chassis. The 540 diameter specification aligns with Losi's engineering standards, ensuring these screws interface perfectly with corresponding threaded holes throughout Losi vehicle designs. The 1 1/4 inch length provides sufficient engagement depth for reliable mechanical strength whilst avoiding over-extension that could interfere with adjacent components. As an RC enthusiast in the UK, you'll appreciate that these genuine Losi fasteners are engineered for reliability in both dry and damp conditions typical of UK outdoor RC sessions. Whether you're running your RC vehicle on track, in grass, or in controlled indoor environments, these fasteners maintain their integrity throughout extended use cycles. The pack of eight provides excellent value and ensures you have spares readily available rather than facing downtime waiting for replacement stock when maintenance is required.

Frequently Asked Questions
- What are button head screws used for in RC cars? — Button head (BH) screws are fasteners with a distinctive rounded, low-profile head design. In RC vehicles, they're used throughout the chassis, suspension mounts, electronics trays, and component assemblies where a compact fastening solution is needed. The button head minimises snagging and looks more refined than traditional fastener styles.
- Why buy genuine Losi replacement screws rather than generic alternatives? — Genuine Losi fasteners are manufactured to exact original equipment specifications, guaranteeing perfect fit and compatibility with your Losi RC vehicle. Generic screws may vary slightly in dimension, thread pitch, or material composition, potentially leading to loose assemblies, stripped threads, or misalignment. Using genuine parts maintains your vehicle's performance and longevity.
- Are these screws suitable for outdoor RC use in the UK? — Yes, these button head screws are designed for use in Losi RC vehicles which are intended for both indoor and outdoor operation. The durable construction handles typical UK weather conditions and the vibration-intensive environment of RC car operation. However, avoid submersion in water unless your specific Losi model is designed to be waterproof.
- How many screws do I need for typical RC car maintenance? — This pack contains eight screws, which is sufficient for replacing fasteners in a specific assembly area or for multiple smaller repairs. If you're performing comprehensive chassis rebuild or maintaining multiple RC vehicles, keeping several packs on hand is advisable.
- Do these screws fit all Losi RC models? — The 540 x 1 1/4 inch specification is used across multiple Losi vehicle designs, but compatibility depends on your specific model. Check your Losi vehicle's documentation or contact RC Model Shop to confirm these screws are appropriate for your particular model before ordering.
- What is the advantage of button head design over other screw styles? — Button head screws have a rounded, low-profile head that looks cleaner and more professional than standard flat-head or pan-head alternatives. The low profile reduces the risk of components snagging on the screw head during operation or transport, and the hexagonal socket provides excellent torque control during installation and removal.
