Our brand new 90° Clamping Tube Hubs offer a great way to attach our .625” diameter hollow tubes together. Eight (8) equally spaced through holes are consistent with all of our other items that have the same 0.770” hub pattern. Precision machined from 6061 T6 aluminum, these clamping hubs 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 included side clamping machine screws are 6-32 and accept a 7/64” hex key.
