Frequently Asked Questions
- Are these screws compatible with my Losi RC vehicle? — Yes, the 4-40 x 1 1/4 inch cap head specification is a standard fastener used across many Losi RC platforms including buggies, trucks, and off-road models. Check your vehicle's manual or parts diagram to confirm compatibility before ordering, as screw requirements vary by model.
- What are cap head screws and why are they better than other types? — Cap head screws feature a distinctive domed head profile that provides superior grip and leverage compared to flat-head or button-head screws. This design reduces the risk of stripped heads during installation or removal and makes tightening and loosening much easier, particularly when working on tight suspension and chassis components in RC vehicles.
- How many screws do I get in this pack? — This pack contains six 4-40 x 1 1/4 inch cap head screws, providing multiple spares for repairs, replacements, or component upgrades across your Losi RC models.
- Will these screws work for upgrades and custom modifications? — The 4-40 x 1 1/4 inch specification is widely compatible with many Losi components and should work with most aftermarket parts designed for Losi vehicles. However, always verify compatibility with your specific parts before purchase, as different components may require different screw lengths or thread sizes.
- What should I do if I strip a screw head? — If you strip a screw head, stop immediately and replace it with a new one from this pack. Using a stripped screw risks damaging the component you're fastening. Always use the correct size hex wrench and apply steady pressure when tightening or loosening to prevent stripping.
