Hex Bore, Face Tapped Clamping Hubs, 0.770" Pattern
These hex bore clamping hubs offer a way to attach hub mount gears or wheels to a 3/8” or 1/2” hex shaft. 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 disadvantage is they are not as equally balanced for high speed use. The side clamping machine screw is 6-32 and accepts a 7/64” hex key. Hex key sold separately.
