Technical Performance
These cap head hex machine screws are manufactured to professional standards using quality steel that resists corrosion and maintains structural integrity through repeated use, fastening cycles, and the occasional impact or vibration that comes with aggressive RC driving. The precision-engineered threads ensure that fastening is predictable and reliable, with no stripped threads or loose connections that could compromise your RC truck's structural integrity. The metric M3 specification means a 3mm diameter shaft with threads that grip securely into ARRMA chassis and component holes, whilst the 16mm overall length positions them perfectly for numerous assembly points across ARRMA's extensive model range, including 1/10 scale brushless RC monster trucks like the GRANITE, KRATON, SENTON and VORTEKS, 1/10 scale brushed models, and even larger scale vehicles including 1/7 and 1/8 scale RC buggies and stadium trucks. The cap head design isn't just aesthetic — it provides a wide gripping surface that distributes torque evenly and prevents the hex driver from slipping, which is crucial when you're servicing a vehicle after a day of racing or bashing. Whether you're replacing fasteners that have corroded, stripped, or simply gone missing, or building additional chassis assemblies from spare parts, these ARRMA screws deliver the quality and reliability that competitive and casual RC enthusiasts alike have come to expect from genuine manufacturer components.
