6" X 4" 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.

Joseph C. ★★★★★

The notch in the inner corner is a thoughtful detail—it keeps the edge clean when I'm working with metal shavings. The beam sits flush against my work stop without any wobble, making setup on my mill consistently accurate.

Thomas ★★★★★

This hardened steel square feels really solid in the hand, and the 6-inch blade length is perfect for my small layout work. The notch at the inside corner seems like a smart detail to keep things clean.

Natalie ★★★★★

The notch at the inside corner is a nice touch—keeps metal shavings from messing up the seating, so it reads true every time. Feels properly dense and solid in the hand, and the hardened steel edges haven’t shown a mark after a week of shop use.
