do you have an alternative and better product then the XYZ Mitee-bite clamps?

we would suggest a locating system clamp with tapered surfaces.
They provide a 0.01mm locating repeatability that is better then the XYZ Mitee-bite clamps which is +/-0.01mm

The pin and the bushing have a center hole so that you can insert a cap screw to clamp the plate.

It's a combination of the following Spanclamps:

APSTM8

and

APRTM8
