The tube clamp has four (4) equally spaced 6-32 tapped holes & are precision machined from aluminium.
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 side clamping machine screw is 6-32 and accepts a 7/64” hex key.
