Try Square

A fixed 90-degree tool for checking and laying out right angles on wood.

What is it?

The try square combines a steel blade and a stock set at exactly 90 degrees. Woodworkers use it to check square edges and faces and to lay out precise right-angle lines.

What is it used for?

  • Checking right angles on stock
  • Laying out square cuts and joints
  • Verifying machine setups

How to choose

Choose blade length by the work (6 or 12 inch common). A cast or rosewood stock with a graduation-stamped blade is a precision staple.

Anatomy

Understanding the parts of a try square 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 try squares 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
