Overview
The Losi Flat Head Screws in Steel with Black Oxide finish represent essential replacement fasteners for RC car builders and enthusiasts across the UK. These M4 x 25mm screws are precision-engineered components designed to meet the demanding requirements of modern RC vehicles, particularly Losi models. Whether you're maintaining your current RC car, rebuilding after a serious bash, or assembling a new model from scratch, having quality replacement screws on hand is crucial for keeping your RC hobby running smoothly.
As a UK RC hobbyist, you understand that reliable fasteners are the backbone of any well-maintained RC car or truck. These Losi-branded screws ensure you're using genuine components that match OEM specifications perfectly, eliminating the guesswork that comes with generic hardware store alternatives. The black oxide steel construction provides excellent corrosion resistance, making these screws suitable for both indoor track racing and outdoor bashing sessions across British weather conditions.
This pack contains 10 individual screws, providing you with multiple spare fasteners to complete repairs, replacements, or full-scale restoration projects on compatible Losi vehicles. The flat head design allows for flush mounting in countersunk holes, creating a clean, professional appearance whilst maintaining structural integrity under the stresses of high-speed RC driving.
Key Features
- Steel Construction with Black Oxide Finish — The screws are manufactured from durable steel and treated with a black oxide coating, which provides superior corrosion resistance compared to standard steel fasteners, making them ideal for RC cars exposed to outdoor conditions and moisture across the UK.
- Precise M4 x 25mm Specification — These screws conform to metric M4 diameter with a 25mm overall length, ensuring they fit perfectly into the counterbored holes on compatible Losi vehicles without any trial-and-error fitting.
- Flat Head Design — The countersunk flat head profile allows the screw to sit flush with the mounting surface, providing a neat finish and reducing the risk of the screw head catching or snagging during assembly or disassembly.
- Genuine Losi Components — As official Losi-branded fasteners, these screws are engineered to OEM specifications and will perform exactly as the manufacturer intended on your RC car or truck.
- Pack of 10 — With 10 screws per pack, you'll have enough spares to complete multiple repairs, replacements, or to stock up for future maintenance without constantly reordering from your RC hobby supplier.
- Universal Compatibility — These screws are designed for use across a range of Losi 1/6 scale models, including the Losi Super Baja Rey SBR 2.0 4WD Brushless Desert Truck RTR, making them a versatile addition to any RC enthusiast's spares collection.
Technical Performance
The Losi Flat Head Screws represent precision engineering in fastener design. Manufactured from quality steel and finished with black oxide coating, these screws deliver the corrosion resistance necessary for RC vehicles that regularly face British weather conditions, from drizzle to muddy outdoor tracks. The M4 diameter provides robust holding power suitable for the mechanical stresses experienced in modern RC cars and trucks, whilst the 25mm length is specifically calculated to penetrate mounting surfaces deeply without protruding excessively or stripping internal threads. The flat head countersunk design is critical in RC applications, as it eliminates protrusions that could catch on terrain during high-speed running or cause aerodynamic drag on competition vehicles. Black oxide finishing not only enhances corrosion resistance but also eliminates glare and provides a professional appearance. These fasteners meet the exacting standards demanded by Losi's engineering team, ensuring compatibility with the Losi 1/6 Super Baja Rey SBR 2.0 4WD Brushless Desert Truck RTR and other compatible models. Whether you're racing at an indoor track, bashing in a quarry, or rebuilding your RC truck after a hard weekend session, these screws will maintain their structural integrity under the constant vibration, impact, and thermal cycling that RC vehicles endure.
What's in the Box
- 10 x Losi Flat Head Screws, M4 x 25mm, Steel with Black Oxide Finish
Frequently Asked Questions
- Are these screws compatible with my Losi RC car? — These M4 x 25mm flat head screws are confirmed compatible with the Losi 1/6 Super Baja Rey SBR 2.0 4WD Brushless Desert Truck RTR in both Yellow and Blue variants. If you own a different Losi model, we recommend checking your vehicle's parts diagram or contacting our RC specialists to confirm compatibility before ordering.
- What is black oxide finish and why does it matter? — Black oxide is a chemical coating applied to steel that significantly improves corrosion resistance compared to bare steel. For RC cars in the UK, where outdoor conditions can expose your vehicle to moisture, salt spray, and humidity, this finish prevents rust formation and maintains the screw's integrity over time, extending the lifespan of both the fastener and the assembled component.
- How many screws do I need per repair? — The number of screws required depends on your specific repair or build project. Common applications use 2-4 screws per assembly point, so this pack of 10 provides enough spares for multiple repairs or complete structural rebuilds on compatible Losi vehicles, with extras left over for future maintenance.
- Why use genuine Losi screws instead of generic hardware store alternatives? — Genuine Losi screws are engineered to exact OEM specifications, ensuring proper fit, thread compatibility, and holding power on Losi vehicles. Generic fasteners may have slightly different dimensions, incompatible thread pitches, or inferior materials that could result in loose assemblies, cross-threading, or structural failure during high-speed RC driving.
- Can I use these screws on other RC vehicle brands? — Whilst the M4 x 25mm specification is a metric standard, compatibility depends on the specific hole patterns and thread pitches of other RC brands. We recommend using brand-matched fasteners for your RC vehicles to ensure perfect fit and performance. Contact our RC specialists for advice if you're unsure.
- Are these screws waterproof? — The black oxide finish provides excellent corrosion resistance and is suitable for outdoor use in wet conditions. However, the screws themselves are not inherently waterproof; the black oxide coating prevents rust formation whilst protecting the steel beneath, making them ideal for RC cars that regularly encounter mud, water, and damp British weather.
