Pro-Grip Clamp Hubs (6mm & 8mm bore)

Reliable Holding Power for Wheels and More!

If you need reliable torque transfer from a motor to a 3D printed wheel, pulley, arm, or gear, Pro-Grip hubs are perfect for you! Designed to work with a wide range of motors including Blitz Lite, Blitz Pro, DartBox Pro, and 6mm shaft DartBox Gearmotors. Made from strong yet lightweight 6061 aluminum with a symmetric single-part design. These secure to a shaft with two included M3 screws, tightened down to your liking for reliable torque transfer. The tightening torque can be tuned to allow slip to prevent damage to a gearbox or mechanism being backdriven on impact for peak reliability. Secure our wheels, gears, pulleys or whatever else with 4X M4 mounting screws.
