Key Features
- Socket Head Cap Design — These screws feature a hexagonal socket in the head rather than a slotted or Phillips drive, allowing you to apply greater torque without risk of stripping the screw head, which is essential for securing critical components on your RC car.
- 4-40 Thread Specification — The 4-40 metric sizing is a standard specification across many Losi RC models and compatible platforms, ensuring perfect compatibility and reliable fitment for your specific vehicle without the need to source alternative fasteners.
- 1/2 Inch Length — This length specification provides the ideal fastening depth for numerous assembly points on RC vehicles, offering sufficient thread engagement while maintaining the lightweight profile necessary for RC performance.
- Black Colour Finish — The black finish provides both aesthetic appeal and protection against corrosion, ensuring these screws maintain their appearance and structural integrity even after exposure to dirt, mud, and outdoor RC bashing conditions.
- Pack of 10 — With 10 screws per pack, you receive excellent value and redundancy in your spare parts collection, meaning you'll always have replacements available for maintenance, repairs, or upgrades without needing to reorder immediately after a single repair job.
- Genuine Losi OEM Parts — These are authentic manufacturer parts, ensuring perfect fitment, reliability, and compatibility with your Losi RC vehicles and providing the peace of mind that comes with using genuine components rather than inferior aftermarket alternatives.
Technical Performance
The LOS Socket Head Screws Z-LOSA6204 represent the engineering precision that Losi applies to every component within their RC vehicle ecosystem. Socket head cap screws are engineered specifically for applications requiring high-strength fastening and repeated assembly and disassembly cycles, making them ideal for the RC hobby where vehicles are frequently maintained, upgraded, and repaired. The 4-40 thread specification provides the optimal balance between holding strength and weight consideration critical to RC car performance. The black colour finish indicates hardened steel construction with protective coating, ensuring these fasteners resist corrosion and maintain structural integrity through countless charging cycles, track sessions, and outdoor adventures. The 1/2 inch length has been precisely calculated to provide sufficient thread engagement on critical assembly points without creating excessive bulk or adding unnecessary weight to your RC setup. These screws are designed to be used with a standard hex driver, allowing you to apply consistent torque without the risk of tool slippage that can occur with Phillips or slotted drives, particularly important when working on precision RC assemblies where one stripped screw can compromise an entire component assembly.
