C-Clamp Set — Heavy Duty

The Zeptix Supplies Heavy Duty C-Clamp Set delivers the raw clamping force needed for metalworking, welding setup, and heavy assembly where lighter clamps would flex. Each clamp is drop-forged from carbon steel and finished in a durable black oxide that resists rust in damp shop environments. The copper-plated acme-thread screw turns smoothly under load and resists the weld-spatter adhesion that freezes plain-steel screws, and the swivel pad at the tip distributes pressure evenly without marring the work surface. The deep throat provides reach beyond the edge of the workpiece, and the wide frame distributes clamping stress without distortion. Use them for holding steel plates during tack welding, securing jigs to drill-press tables, pressing bearings into housings, or any situation where you need serious, immovable holding power. Available as a pair of 4-inch clamps for lighter fabrication or a set of four 6-inch clamps for heavy structural work. These are the no-compromise clamps that outlast the tools they hold together.
