A universal clamp apparatus for orthopedic exterior fixators is disclosed. Preferably, the universal clamp apparatus has two pin/rod clamps, each having seating grooves for attaching to a frame rod associated with a frame of the fixator and/or a bone pin for implantation in a bone fragment. A clamp screw extends through and connects the first and second pin/rod clamps. An ergonomically designed knob having at least one collapsible or non-collapsible turn lever acts as a torque amplifier when rotated by hand without tools to tighten and untighten the pin/rod clamps to the frame rod and/or bone pin by movement along the clamp screw. The pin/rod clamps have planar sides that are contiguous and have radial ratchet grooves that are in mating engagement and provide a ratcheting mechanism so that the rotation of the pin/rod clamps relative to each other occurs in incremental rotational steps.
