Extra Hard Steel Pinion Gear 5mm Bore Mod0.8 16T (RRP8716)

This Extra-Hard 5mm-bore pinion gear, 0.8 module with 16 teeth, is built for durable performance in brushless RC car setups. Made from high-carbon steel and precision machined, it delivers reliable, smooth engagement with a matching spur gear. Each pinion is stamped with the tooth count for quick identification, and a 4mm set screw is included; a 2mm Allen wrench is required to tighten it (not included). It is designed to fit a 5mm motor shaft, with a 5mm-to-1/8-inch reducer sleeve required for motors with a 1/8-inch shaft.

Note on compatibility: 32 pitch gears and 0.8 module gears can be used together without increased noise or wear. The main difference is that 0.8 module gears have a slightly larger outside diameter per tooth (about 0.00027 inches).
