#25 Pitch Set-Screw Sprocket (8mm REX™ Bore, 12 Tooth)

SKU: Build System: goBILDA

The 8mm REX bore of this 12 Tooth sprocket enables awesome positive drive on 8mm REX™ shafting–such as that of our 5203 or 5204 Series Yellow Jacket Planetary Gear Motors.

Importantly, its 8mm long protrusion matches the thickness of standard Sonic Hubs. This makes exact alignment a breeze when it’s paired with a larger sprocket mounted to a Sonic Hub!

Its steel construction also excellently resists wear, tear, and corrosion.
