Designed for RC cars, this 29-tooth, 0.8-module Safe-D5 pinion gear transfers motor power to the drivetrain with smooth, reliable engagement.

Made from tough steel for lasting performance in demanding RC conditions, it features a wide tooth profile for consistent meshing and a D-shaped bore that matches the motor shaft to help keep the pinion secure even if the set screw backs out. It fits 5mm motor shafts and includes an M4 x 4mm set screw plus a 3.2mm E-clip for retention.
