Our verdict

A light alloy steel C-clamp from Irwin with a pad on the screw end. The strength figure is listed in pounds per square inch, which is a pressure rating and not a clamping force.

Overview

A hobbyist or woodworker holding glued stock gets a small alloy steel C-clamp with a pad to protect the surface. It is a regular C-clamp style in silver, sold as a single unit.

A light frame with a pad suits delicate surfaces and quick setups. The strength figure is given as a pressure value, so real clamping force cannot be read from the listing, and no throat depth is stated.

Who it's for

Glue-ups, small frames and craft projects that must not be dented suit a padded C-clamp. Heavy fabrication needs a larger clamp rated in pounds of force.

Pros and cons

Pros
  • Pad protects the work surface
  • Alloy steel frame
  • Regular C-clamp style
Cons
  • Strength given as a pressure figure
  • Throat depth not listed
  • Warranty terms not detailed
  • Single clamp only

Performance notes

The pad spreads the screw pressure across a wider area, which is why it marks soft wood less than a bare screw tip. Clamping force depends on the screw torque and the frame. The listed strength is a pressure rating, so it does not translate to a load limit.
