C-Clamp

A C-shaped clamp with a threaded spindle for firm, adjustable clamping across a range of thicknesses.

What is it?

The C-clamp is a C-shaped frame with a threadable spindle that clamps material between the fixed jaw and clamp pad. It holds work of many thicknesses and is a workshop standard for gluing and holding.

What is it used for?

  • Gluing and clamping workpieces
  • Holding parts to a bench
  • Light fixture and repair clamping

How to choose

Match throat depth and opening to the work thickness. Steel for strength, deeper throat for reach.

Anatomy

Understanding the parts of a c-clamp helps you use, maintain, and buy it with confidence.

  • Body: the main working portion of the tool
  • Working end: the part that contacts the material
  • Handle: the part you grip for control and leverage

Materials & construction

Quality c-clamps are made from hardened, heat-treated steel (often chrome-vanadium or high-carbon) chosen for strength, edge retention, and resistance to wear and corrosion.

Safety & maintenance

  • Inspect the tool before use and replace any that are worn or damaged
  • Use the right tool for the job and apply controlled force
  • Store tools clean and dry to prevent corrosion
  • Wear appropriate eye protection for the work
