Overview
A threaded screw drives the pad against the work in each of these two C-clamps, closing against a fixed frame cast in iron. They are plain screw clamps with no quick release.
Two clamps cover a basic hold on a bench or fixture, and the tensile figure gives a load limit to work from. The material fields disagree, so the metal type is unclear.
Who it's for
Hobbyists and shop users who hold stock down while they cut, glue or weld get two basic clamps. People who must know the reach, or who want faster action, should compare other clamp types.
Pros and cons
- Two clamps in the pack
- Stated tensile strength
- Heavy duty style
- Simple screw action
- Material fields disagree
- Throat depth not listed
- Slow screw adjustment
Performance notes
Holding force comes from the screw thread and the stiffness of the frame, so a stiff frame resists spreading under load. The tensile figure marks the limit for the frame. Reach to the work depends on a throat depth the listing does not state.
