Built for fast, no-fuss clamping, this 12 inch heavy duty F-Clamp is made from drop forged, heat treated, nickel chrome plated steel for rugged performance. Its 120mm throat and simple slide-and-tighten setup make it up to 90% faster than C-Clamps. A copper coated screw and handle help protect against weld spatter, so you can keep working with less cleanup and more confidence.
