Unique-Bargains 10-2.5A wire cap connector 10 teeth 2.5mm 20pcs

20-piece gear wheel set

This pack supplies twenty white plastic gear wheels each cut with ten teeth and a 2.5mm centre hole. The parts measure 25mm in diameter by 4mm thick and are intended for DIY science, product design or small mechanical models. The small size and light material make them suitable for low-torque educational or hobby projects.

Verify shaft size and torque needs

Before ordering confirm that the driving shaft is exactly 2.5mm in diameter so the bore fits without modification. Ensure the application torque stays within the limits of a small plastic gear, as higher loads will strip the teeth or deform the bore. The white colour may show wear or dirt more visibly than darker plastics.

Fits RC cars and custom mechanisms

The gear wheels install directly onto a 2.5mm motor or axle shaft in RC toy cars or scratch-built mechanisms. They transmit motion between parallel shafts spaced to match the 25mm pitch diameter, freeing the builder from machining custom gears. No additional hardware is included, so retainers or set screws must be sourced separately.
