12-Pack 6-Inch C-Clamp Set

This 12-pack of PONY 2660 C-clamps supplies a workshop or job site with consistent 6-inch opening capacity and 3-1/2-inch throat depth. Each clamp is built from ductile iron casting with a zinc-plated acme threaded screw for smooth adjustment. The powder-coated orange finish resists corrosion during daily use. A load limit of 1,000 pounds per clamp handles demanding woodworking and household tasks.

Upgrade from single-clamp purchases

Buying the 12-pack replaces the need to source individual clamps over time and ensures uniform jaw dimensions across every workpiece. The jump is worth it when a project requires multiple identical clamping points or when a shop wants to standardise on one model for repeatable setups. Builders who need deeper throat depth or larger opening capacity will need a different clamp design.

Sustained clamping under full load

Under the rated 1,000-pound load limit the ductile iron frame resists deflection and the acme thread maintains pressure without slipping during long glue-ups or fabrication holds. The zinc-plated screw threads continue to turn smoothly after repeated tightening cycles. The powder-coated finish protects the casting from moisture and shop chemicals during extended clamping sessions.

Questions about this item

How much clearance does the 3-1/2 inch throat depth give between the screw and the frame?

The 3-1/2 inch throat depth measures from the centre of the screw to the inside of the frame, so that is the maximum reach over a workpiece edge.

What is the correct way to apply force with the zinc plated acme threaded screw?

Tighten the screw by hand until the pads contact the work, then give a firm turn with the tommy bar — do not use a cheater pipe or impact driver.

When should the ductile iron clamp casting be retired from service?

Replace any clamp that shows cracks, bent frames, stripped acme threads or a load limit that can no longer hold 1,000 pounds.
