Key Features
- M3 x 4mm Specification — These set screws are precisely dimensioned to M3 metric standard with a 4mm length, ensuring they fit correctly into Losi RC components and maintain proper engagement without over-tightening or bottoming out.
- Cup Point Design — The cup point head style creates a concave socket that grips cylindrical shafts and pins with superior holding power, making these screws ideal for securing rotating components and adjustable elements that must remain firmly in place during aggressive driving.
- Hex Driver Type — These screws feature a hexagonal socket head, allowing you to tighten and remove them with standard hex wrenches or hex drivers, ensuring you can work on your RC car with tools you already have in your collection.
- Machine Thread Construction — The machine thread design provides reliable, repeatable engagement with threaded holes in your RC components, delivering consistent clamping force and preventing loosening from vibration during high-speed running.
- Black Finish — The black colour provides corrosion resistance and a professional appearance, protecting the steel fasteners from rust and oxidation whilst maintaining the aesthetic appeal of your RC model's internal components.
- Pack of 10 Screws — This convenient pack includes ten individual set screws, providing multiple replacements for maintenance across several vehicles or ensuring you always have spares when you need them most.
- Genuine Losi Component — These are authentic OEM Losi parts manufactured to the same specifications and quality standards used in new Losi RC vehicles, guaranteeing compatibility and reliability across the full Losi product range.
Technical Performance
Losi set screws are manufactured to precise metric specifications, ensuring they perform reliably in the demanding environment of RC vehicle operation. The M3 x 4mm dimensions have been engineered to provide optimal engagement depth without creating stress concentration or causing thread stripping in the receiving component. The cup point design distributes clamping force across a wider contact area on cylindrical shafts compared to flat-point alternatives, dramatically reducing the risk of component rotation or slippage under load. The machine thread construction provides consistent pitch and reliable engagement, crucial for maintaining assembly integrity during acceleration, braking, and cornering forces that can exceed 2G in competitive RC racing. These fasteners are manufactured from hardened steel with a black finish that provides excellent corrosion resistance, essential for RC vehicles that may be exposed to damp UK weather conditions or driven through wet grass and muddy terrain. The hexagonal socket head allows precise torque application without risk of cam-out or bolt damage, critical when working on expensive carbon fibre and aluminium RC components where proper fastener engagement is essential. Whether you're maintaining a 1/10 scale RC car, a 1/8 scale buggy, or any other Losi-equipped model, these set screws deliver the engineering precision and reliability you expect from a leading RC manufacturer.

Frequently Asked Questions
- What are set screws used for in RC cars? — Set screws are precision fasteners used throughout RC vehicles to secure components that require tight, reliable holding without full penetration through the part. They're commonly used to lock shafts in place, secure adjustable components, hold pins and bushings, and maintain the position of critical assembly elements that experience vibration during high-speed driving.
- Why choose genuine Losi set screws instead of generic alternatives? — Genuine OEM Losi fasteners are manufactured to exact specifications that match the threaded holes and receiving components in Losi RC vehicles, ensuring perfect fit and reliable engagement. Generic alternatives may have slight variations in thread pitch, head geometry, or material specification that can result in poor seating, difficulty tightening, or premature loosening during use.
- Are these set screws compatible with all Losi RC models? — M3 x 4mm cup point set screws are used across many Losi RC vehicles and replacement components. However, we recommend confirming the specific fastener requirements for your particular model before ordering. Contact our team for assistance in identifying the correct fasteners for your Losi RC car.
- What tools do I need to install these set screws? — The hexagonal socket head requires a hex wrench or hex driver in the appropriate size (typically a 2mm or 2.5mm hex key, though size may vary). Most RC enthusiasts already have these common tools as part of their basic RC toolkit.
- How many set screws might I need? — This depends on your specific RC model and maintenance needs. A pack of 10 screws provides multiple replacements for several vehicles or a good spare supply for regular maintenance and repairs. For heavily used competition vehicles, having multiple packs on hand ensures you're never without essential fasteners.
- Is this suitable for beginners? — Absolutely. Beginners learning to maintain and repair their RC cars will find set screws relatively straightforward to work with, requiring only basic hex tools and understanding of fastener principles. Having genuine Losi fasteners ensures your learning experience involves proper components that won't complicate your maintenance tasks.
