Technical Performance
These M3x5mm set screws represent the kind of engineering excellence you'd expect from ARRMA, a leading manufacturer in the RC hobby. The super-tough steel material provides exceptional strength-to-weight ratio, critical for precision fastening in high-vibration environments. The precision-manufactured threads ensure that repeated installation and removal cycles don't cause the screw to become loose or stripped, maintaining a secure grip over the life of your RC vehicle. Whether you're working with brushless RC motors, suspension brackets, or electronic components, these screws deliver consistent performance. The hex head design ensures compatibility with standard RC tool sets and hex key drivers, eliminating the need for specialised equipment. Machine thread construction means these screws create their own threading path, making them ideal for securing into pre-drilled holes in plastic and metal components common to ARRMA RC cars. The 5mm length is engineered to provide adequate penetration for secure fastening whilst avoiding over-tightening that could damage delicate RC components.

Carrying spare set screws in your RC tool box means you can perform emergency repairs on the track or at the field without interrupting your session.

Beginners will find them useful for learning basic assembly and maintenance, whilst experienced racers appreciate having OEM replacements on hand for emergency repairs.
