This shaft coupler is perfect for connecting two shafts together. It is made of durable metal and features a 2mm coupling on one end, with a 5mm coupling on the other. It is easy to use and makes connecting shafts a breeze.

These work well for connecting motors to driveshafts and other intermediate connections. The coupler has two set screws on each side to hold each shaft in place. On the 2mm side these couplers work well with our 3-6V Hobby Motor and 2mm Diameter Shaft. The 5mm side will fit on most of our Stepper Motors and DC Motors.
