A Machinist Square with a Wide Base is a precision tool specifically designed for the needs of machinists, metalworkers, and engineers who require accurate right-angle measurement and marking in their work. The wide base adds stability and makes it particularly well-suited for use on large or heavy workpieces, providing a reliable reference for ensuring squareness and alignment.
Din 875 Grade 2, which is the normal standard for a decent workshop squares. A grade 2 square has always been recognised as being quite sufficient for normal workshop use.
A machinist square or engineer's square is the metalworkers' equivalent of a try square. It consists of a steel blade inserted and either welded or pinned into a heavier body at an angle of 90°. Usually a small notch is present at the inside corner of the square. This prevents small particles from accumulating at the juncture and affecting the square's reading.
