Standard ground clamps have a spring at the pivot point of the handle to hold the clamp in place. The quick action handle provides fast clamping to flat and round surfaces.

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.

Flat-jaw ground clamps have textured jaws to grip flat surfaces such as bar stock and metal plate. A spring keeps the jaws tight to the surface.

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.

Cantilever ground clamps have a V-groove cut in the floating jaws to center and hold pipe without rolling. Floating jaws pivot to adjust to irregular shapes and uneven surfaces.

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.

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.
