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 depth, also known as throat depth or simply throat, refers to the distance from the edge of the clamping mechanism (such as the jaws of a clamp) to the nearest obstruction or the fixed part of the clamp. In other words, it's the maximum depth or reach into which the clamp can securely hold an object.

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.
