Technical Performance
The RC4WD Z-S0030 M4 20MM LONG THREADED SHAFT (SET SCREWS) represents the kind of precision engineering that defines RC4WD's reputation in the scale RC community. Each set screw is manufactured to exacting metric standards, ensuring that threading depth, shaft diameter, and length specifications remain consistent across every unit in the pack. The M4 specification means these shafts have a 4mm nominal diameter with metric fine threading, providing excellent holding power and vibration resistance when properly torqued. The 20mm overall length has been specifically engineered to work within the confined spaces of modern RC chassis and link assemblies whilst maintaining adequate thread engagement for secure connections. The set screw design minimises the risk of accidental loosening caused by vibration, a common problem in off-road RC environments where vehicles encounter rough terrain and high-frequency impacts. RC builders appreciate the reliability of metric fasteners because they integrate seamlessly with modern RC engineering practices and component specifications. Whether you're adjusting anti-roll bar mounts, installing solid link assemblies, or fine-tuning suspension geometry on your 1/10 scale RC crawler or other precision RC builds, these threaded shafts deliver the consistent performance and longevity that serious hobbyists expect from quality RC components.

Frequently Asked Questions
- Are these M4 threaded shafts compatible with my RC car? — Yes, these Z-S0030 set screws are compatible with any RC vehicle or scale model that uses M4 solid links or M4-specification connection points. They work across RC crawlers, buggies, trucks, and other platforms from RC4WD and other manufacturers that follow metric M4 standards. Before purchasing, simply verify that your RC components are specified for M4 connections.
- What tool do I need to install these set screws? — Installation and adjustment requires the RC4WD 2.0mm Metric Hex Driver Tool, which is a standard implement for metric fastener work. Once the set screws are initially installed with this tool, they can typically be tightened or loosened by hand for quick field adjustments during RC outings.
- How many set screws should I buy for my RC setup? — Each pack contains ten set screws. The quantity you need depends on your specific RC build and how many connection points you're establishing. Many RC builders keep multiple packs on hand because having spare fasteners means you can experiment with suspension geometry and component configurations without delay.
- Will these work with RC4WD solid links? — Yes, these M4 20mm long threaded shafts are explicitly designed to work with M4 solid links, which are commonly used in RC4WD builds and comparable scale RC projects. This makes them an ideal refresher pack if you're rebuilding existing link assemblies or establishing new connection points on your RC model.
- Are these set screws suitable for beginners? — Absolutely. These straightforward metric fasteners are perfect for RC builders of any experience level. Beginners appreciate their simplicity and the way they integrate with standard RC assembly practices, whilst experienced builders rely on them for precision maintenance and geometry adjustments across their RC fleets.
- What is the difference between set screws and standard bolts? — Set screws feature a conical or cylindrical point that digs into mating surfaces, creating a secure friction-based lock that resists vibration better than standard bolts with flat heads. In high-vibration RC environments where vehicles constantly encounter impacts, this design makes set screws the preferred fastener choice for critical connections.
