625046 0.250" to 0.3125" Clamping Shaft Coupler

0.250" to 0.3125" Clamping Shaft Coupler

Our clamping shaft couplers offer an inexpensive way to attach or lengthen various shafts. These couplers offer two equally spaced 5-40 tapped holes with screws and are precision machined from aluminum. Clamping couplers offer several advantages over set screw hubs. First, they do not damage the shaft which they are attached. Second, they offer more holding power in high torque applications. The disadvantage is that they are not as equally balanced for high speed use. These hubs use a 3/32” Hex Key (sold separately).
