Parallel Handscrew Clamps
The matching jaws are ground flat for a firm grip and even pressure when clamping smooth surfaces. The two screws turn independently to make small, individual adjustments to each jaw.
Parallel-Jaw Bar Clamps/Spreaders

The large, flat jaws remain parallel when clamping to apply even pressure without denting or marring the workpiece. Reverse the arms to use these clamps as spreaders. Pull the handle to lock or release the clamping arm.
