Which clamp provides high clamping torque for medium-sized workpieces?

• A. Quick Clamp
• B. Medium C Clamp
• C. Strap Clamp
• D. Pocket Hole Jig

Answer: (B)

Clamping torque comes from the clamp’s mechanism and how it’s meant to hold a piece. A medium C clamp uses a screw-driven mechanism that lets you apply a strong, controllable bite with a compact jaw area, which is ideal for medium-sized workpieces where you need solid pressure without a large clamping setup.

Quick clamps are convenient for fast, light holds but typically don’t reach the same high torque as a screw-driven clamp, so they’re not the best choice when you need maximum holding force. Strap clamps spread pressure along a long edge and are great for wide panels, but their force is distributed and depends on strap tension rather than delivering high torque at a single point. Pocket hole jigs are not clamps at all; they’re guides for drilling and don’t provide clamping force.

So, for high clamping torque on medium-sized workpieces, the medium C clamp is the best option.
