Each package contains two (2) gears, and four (4) set screws!
Looking to make a compact, bulletproof geared drivetrain with Blitz, DartBox or other 4mm or 6mm shaft motors? Need a way to drive a lifting arm, saw arm or flipper? These steel pinion gears are for you! This is a standard 12 tooth mod 1 gear perfect 5mm and 6mm shaft gearmotors! These gears will lock onto the motor shaft with an included pair of steel set screws 90 degrees apart. These Module 1 gears are compatible with any other Mod 1 gears on the market, or those you can lasercut or 3D print. Blue Loctite (or other medium strength threadlocker) is recommended for use with the set screws. Make sure one set screw is secured on the flat of your motor shaft for ideal torque transfer.
