Overview

A workbench where boards or metal parts need holding down gets four C-clamps that close with a screw against a fixed frame. They are plain screw clamps with no quick release.

Four clamps in one set cover several holds at once, and the tensile figure gives a stated load limit. Fields disagree on the material, and the jaw reach is never given, so check the reach against your stock.

Who it's for

Woodworkers and metal hobbyists who need several basic clamps for benches and fixtures can use the set. Buyers who need a known throat depth, or one-handed operation, should shop other clamp types.

Pros and cons

Pros
  • Four clamps in one set
  • Stated tensile strength
  • Heavy duty style
  • Simple screw action
Cons
  • Material fields disagree
  • Throat depth not listed
  • Slow screw adjustment

Performance notes

A C-clamp holds by turning a screw against a fixed frame, so holding force depends on the stiffness of the frame and on the thread. The tensile rating gives the load limit. Without a listed throat depth, the reach to the work is the open question.
