Frequently Asked Questions

• What are set screws used for on RC vehicles? — Set screws, also known as grub screws, are used to secure components like pinion gears, shafts and other drivetrain parts in place. They work by creating a fixed connection between two components without requiring a bolt to pass all the way through, making them ideal for precise RC applications where space is limited and weight must be minimised.
• Are these M3 x 5mm set screws compatible with my RC4WD vehicle? — These screws are specifically engineered for RC4WD applications and are confirmed as direct fits for RC4WD Punisher Shafts and the Z-S0118 component. They are also suitable for pinion gear work on RC4WD TF2 and G2 platforms. If you own other RC4WD models, consult your build documentation or contact us to confirm compatibility with your specific vehicle.
• What tool do I need to install these set screws? — These M3 x 5mm set screws require the RC4WD 1.5mm Metric Hex Driver Tool for installation and adjustment. This is the standard tool for working with RC4WD fasteners, and most RC builders in the UK will already have one in their workshop.
• Why choose Grade 2 steel instead of cheaper alternatives? — Grade 2 steel provides superior hardness and strength compared to lower-grade fastening materials. This means your set screws will resist stripping, handle repeated tightening and loosening without degrading, and maintain secure holding strength through the vibrations and stresses inherent in RC driving. For RC enthusiasts who want reliability over false economy, Grade 2 steel is the only sensible choice.
• How many set screws come in this pack? — This pack contains 10 individual M3 x 5mm set screws, providing sufficient quantity for multiple assemblies, replacements and future projects without requiring frequent re-ordering.
• Can I use these screws for other RC vehicle brands? — While these screws are specifically engineered for RC4WD applications, the M3 x 5mm specification is a standard metric size that may be compatible with other RC vehicles using similar components. However, we recommend confirming compatibility with your specific vehicle before purchase to ensure perfect fitment and performance.
