16T 0.8Mod 1/8 Bore CNC Steel Pinion Gear (ARA311078)

This 16-tooth, 0.8-module CNC steel pinion gear is built for 1/8-inch (3.175 mm) motor shafts, helping to tune the gear ratio on an RC vehicle. Precision CNC machining delivers accurate teeth and durable performance in demanding conditions.

With a wide tooth profile for smooth meshing, the gear features a laser-etched tooth count for quick identification and a threaded hole for a securing set screw. An M4 x 4 mm set screw is included to lock the gear firmly onto the shaft.
