Spring-loaded ground clamps have a spring at the end of the handle to create a stronger connection to the workpiece than standard ground clamps. The quick action handle provides fast clamping to flat and round surfaces.

C-style ground clamps have wide jaws for clamping thick materials. They tighten to the workpiece using the integrated hand screw, which allows the clamp tension to be manually adjusted for work where a standard clamp might be dislodged.

The magnetic holding power on these ground clamps can be turned on and off so the clamp can be easily positioned. Turning the magnet off also prevents metal shavings and parts from being attracted to the magnet when it's not in use. Magnetic ground clamps attach to any magnetic surface. They're often used on large surfaces where an edge isn't convenient for attaching standard clamps.
