4" X 3" Machinist square made of hardened tool steel.

Length of blade is measured from inner edge of beam to end of blade. The small notch at the inside corner prevents small particles from accumulating at the juncture and impacting the squares reading.

Typical use involves aligning the beam along one edge of an object with the blade across the body of the work. Using a strong light source behind the square will reveal any gaps showing the squareness of the work.

Customer Reviews (4.8 / 5 · 5 reviews)

Alexander ★★★★★

The beam is perfectly square to the blade, and the notch at the inner corner kept sawdust from interfering with my measurement. Slides smoothly against my workpieces and feels substantial in the hand.

David ★★★★★

I had a tiny burr on the edge when it arrived, but a quick pass with a stone cleaned it up perfectly. The notch at the inside corner is a thoughtful touch that keeps debris from messing up my measurements.

Riley Y. ★★★★★

The hardened tool steel feels incredibly solid in hand, and the blade length measurement from the inner edge is exactly what I needed for precise layout work. It's a simple but perfectly made tool.
