Spark-Duty Drop Forged C-Clamp, 0 -8-1/4 in. Opening, 4-15/16 in. Throat Depth

Get professional-grade clamping with 7,600 lbs. of force, opening to 8-1/4 in., and a 4-15/16 in. throat depth. Designed specifically for welding and steel fabrication, the copper-plated spindle prevents weld spatter from fusing to threads, extending clamp life in high-spatter environments. Drop forged steel construction provides the frame strength needed to hold heavy plate, structural members, and pipe fixtures under the thermal stresses of welding operations. The hardened acme thread spindle maintains smooth rotation even after prolonged heat exposure, ensuring consistent tightening throughout the workday. A swivel pad at the spindle tip conforms to workpiece surfaces, distributing clamping force and reducing the risk of surface deformation on critical weldments. The Spark-Duty series is the professional fabricator's choice for clamps that perform in demanding thermal environments.
