Engineering Square with Base
A machinist square or engineer’s square is the metalworkers’ equivalent of a try square. It consists of a steel blade inserted and either pinned into a heavier body at an angle of 90°. There is evidence of pinning at the intersection of the blade and body: The heads of three pins are visible as dark circles. A small notch has been added to the inside corner of the square to prevent small particles from accumulating and affecting the square’s reading.
