Pinion Gear 1/8" Bore 32P 12T (RRP0120)

32P alloy pinion gear with a 1/8-inch bore and 12 teeth, designed for use with plastic spur gears. Not heat treated and not stamped with the tooth count, this pinion is a straightforward, economical option for 32P gear systems. A 5-40 set screw is included to secure it to the shaft, and a 1/16-inch Allen wrench is required to tighten the screw (wrench not included).

Designed for standard 1/8-inch shaft configurations, this pinion pairs with plastic spur gears to form a reliable 32P gear train. The included set screw keeps the gear firmly attached to the shaft, making installation straightforward for hobbyists.
