Light-Duty C-Clamp

The Wilton H566N is a cast-iron C-clamp built for light-duty clamping tasks. It provides a maximum jaw opening of 1-1/4 inches and a throat depth of 1-3/16 inches. A zinc-plated steel spindle with a thumbscrew handle applies force through a flat, swivel jaw pad. The gray powder-coated finish protects the iron body from corrosion.

Workpiece Fit

This clamp suits jobs that need up to 550 lb of clamping force on small workpieces. The 1-1/4 inch maximum opening limits it to thinner materials. Buyers who need to clamp thicker stock or require higher pressure for heavy fabrication should look at larger or stronger models.

550 lb Clamping Force

The rated clamping force of 550 lb is the single figure that decides if this tool matches the job. It determines whether the clamp can hold the workpiece securely without slipping or damaging the material. Verify that your application stays within this limit before purchasing.

Questions about this item

How do I confirm the clamp is holding at its full 550 lb rating after tightening?

Tighten the zinc-plated steel spindle with the thumbscrew handle until the flat swivel pad contacts the workpiece evenly; the cast-iron frame and powder-coated finish keep the throat depth at 1 3/16 in so the rated force is applied squarely.

What comes in the box and what must I supply myself?

The clamp ships fully assembled — cast-iron body, steel spindle, zinc plating, powder-coated finish, flat swivel pad and thumbscrew handle are all included; no extra parts or accessories are required for basic clamping tasks.

Which Wilton C-Clamp model should I choose for a 1-1/4 in jaw opening and 550 lb capacity?

The H566N is the only model in this listing with a 1-1/4 in maximum jaw opening, 1 3/16 in throat depth and 550 lb clamping force, so it matches those exact requirements.
