Technical Performance
These M3x20mm button head cross machine screws represent the kind of precision engineering that ARRMA applies throughout its RC vehicle lineup. The 3mm diameter provides an excellent balance between holding strength and component compatibility, allowing these fasteners to be used in numerous locations throughout your RC car without over-sizing or creating stress concentrations in plastic or composite materials. The 20mm length ensures adequate engagement depth for secure mounting whilst remaining short enough to work in confined spaces where larger fasteners would not fit. The super-strong steel material has been selected for its reliability and resistance to corrosion, ensuring these screws maintain their integrity through repeated use, exposure to dirt and moisture during outdoor RC operation, and multiple removal and re-installation cycles during maintenance. The precision-manufactured threads guarantee consistent pitch and geometry, which is essential for achieving proper torque values without risking thread stripping in plastic components. The button head profile provides a clean, finished appearance whilst the cross-drive recess ensures reliable tool engagement and reduces the risk of damage to the fastener head during installation. For RC enthusiasts in the UK who regularly service their ARRMA ready to run vehicles or perform upgrades and repairs, having a supply of these authentic replacement screws is a practical investment in maintaining optimal vehicle performance and appearance. The pack of 10 provides excellent value, ensuring you're never caught short when undertaking mid-season maintenance or performing repairs at the track or field.
