Steel Pinion Gear 1/8" Bore 48P 12T (RRP1012)

12-tooth, 48-pitch pinion gear crafted from hard nickel-plated alloy steel is designed to mesh with a plastic spur gear for durable, long-lasting performance. The tooth count is stamped on the gear for quick identification, and it features a 1/8 inch bore to fit standard shafts.

One 5-40 set screw is included for secure mounting, and a 1/16 inch Allen wrench fits the set screw (not included). This pinion provides smooth, precise engagement with compatible spur gears, offering reliable power transfer in drive-train setups that call for 48 pitch, 12T pinions.
