Overview

The Losi Set Screw M3 x 3mm (10) is an essential spare parts component for RC enthusiasts and hobbyists who maintain their own RC models. Whether you're running a Losi RC car, buggy, truck or other scale model, set screws are fundamental fastening components that secure various mechanical elements in place. This pack contains ten individual M3 x 3mm set screws, providing you with multiple replacements to keep your RC vehicle in peak operating condition. As a UK RC hobbyist, having spare set screws on hand is crucial for quick repairs and maintenance between racing sessions or casual bashing adventures.

Set screws play a vital role in RC model assembly and maintenance, holding everything from motor shafts to gear carriers and suspension components securely in position. The M3 x 3mm specification makes these screws compatible with a wide range of Losi RC models and similar scale vehicles. Whether you're a seasoned RC racer maintaining competition equipment, a weekend basher enjoying off-road adventures, or a dedicated RC enthusiast constantly tuning and upgrading your setup, having spare set screws ensures you're never held back by missing fasteners. These are genuine Losi parts manufactured to the exact specifications your RC car demands.

Sourcing quality spare parts from an authorised UK RC retailer like RC Model Shop ensures you receive genuine Losi components that fit perfectly and perform reliably. Rather than settling for generic fasteners from general hardware stores, Losi set screws are engineered specifically for RC applications and designed to withstand the vibrations, impacts and stresses of RC model operation. Keeping a stock of these essential spares means you can perform quick field repairs at the track, get back in the action, and maintain your RC models without delays.

Key Features

  • M3 x 3mm Specification — These set screws conform to M3 metric threading and 3mm length, making them compatible with a comprehensive range of Losi RC vehicles and similar scale models that utilise this standard fastener size.
  • Pack of Ten — This pack contains ten individual set screws, providing multiple spares so you have replacements on hand for repairs, maintenance and regular wear replacement without needing to reorder frequently.
  • Genuine Losi Parts — Manufactured by Losi specifically for RC applications, these set screws meet the exact engineering specifications and quality standards required for reliable RC model performance.
  • Essential Maintenance Component — Set screws are fundamental fastening elements that secure motor shafts, gear carriers, suspension linkages and numerous other mechanical assemblies, making replacements essential for any serious RC enthusiast.
  • Quick Field Repairs — Having spare set screws available means you can perform rapid repairs at the track, field or bashing location without waiting for delivery or supply shortages interrupting your RC sessions.

Technical Performance

The Losi Set Screw M3 x 3mm represents a precision fastening solution engineered for the demanding requirements of RC model operation. These metric-threaded set screws are manufactured to exacting standards that ensure they seat properly in threaded holes, hold securely under vibration and rotational stress, and can be removed and reinstalled multiple times without stripping or becoming damaged. The M3 x 3mm sizing makes these screws ideally suited for smaller-scale RC applications where precise fastening in confined spaces is required. Whether securing motor shafts to pinion gears, holding suspension arms in place, or fastening various mechanical assemblies throughout your Losi RC vehicle, these set screws deliver the reliability and consistency that serious RC enthusiasts demand. The quality of genuine Losi fasteners ensures compatibility and performance that generic hardware store alternatives simply cannot match, particularly when subjected to the repetitive impacts, vibrations and stresses inherent in RC model racing and bashing.

Frequently Asked Questions

  • What are set screws and why do I need them for my RC car? — Set screws are headless fasteners with internal threads that secure components onto shafts and in drilled holes. In RC vehicles, they hold critical elements like motor shafts, gear carriers and suspension linkages firmly in place. Over time, vibration and impact can loosen or strip set screws, making replacements essential for maintaining your RC model's performance and preventing component failure during operation.
  • Will these M3 x 3mm set screws fit my Losi RC model? — The M3 x 3mm specification is a standard metric sizing used across many Losi RC vehicles and similar scale models. To confirm compatibility with your specific model, consult your vehicle's instruction manual or parts diagram. Having spare set screws of this size is valuable for any RC enthusiast with multiple Losi models or compatible vehicles.
  • How often do I need to replace set screws on my RC car? — Set screw replacement frequency depends on your driving style and maintenance habits. Aggressive bashing and racing put more stress on fasteners and may require more frequent replacement. Regular inspection during maintenance sessions helps identify loose or damaged set screws before they cause problems. Keeping spare set screws on hand ensures you can perform immediate replacements whenever needed.
  • Are these genuine Losi parts or generic alternatives? — These are genuine Losi set screws manufactured specifically for Losi RC vehicles. Genuine parts ensure proper fit, correct metallurgy for RC application demands, and compatibility with your RC model. Authorised UK retailers like RC Model Shop supply only authentic Losi parts, guaranteeing quality and reliability that generic fasteners cannot provide.
  • Do I need any special tools to install set screws? — Set screws typically require a hex key or similar wrench tool that fits the internal socket of the fastener. Most RC enthusiasts already own the necessary tools as part of their basic RC tool kit. Installation is straightforward: simply insert the hex key, thread the set screw into the receiving hole, and tighten to secure the component in place.
