Clamping capacity, also known as clamping span, refers to the maximum distance or size that a clamp can effectively grip or hold. In other words, it's the maximum width or diameter of the object that the clamp can accommodate.

Clamping force is the pressure a clamp applies to hold an object in place. It's determined by the clamp's design, materials, tightening mechanism, and user's force. It's often measured in pounds or newtons. Proper clamping force ensures stability without damaging the object or the clamp itself.
