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. The purpose of this action is to check for squareness or to mark out the body of the workpiece. An engineer’s square is a simple yet versatile hand tool, widely used across many industries, disciplines and projects. Also called machinist squares, they are normally L-shaped metal tools sold in various sizes. Engineers squares are used to accurately check and mark angles, or to verify the squareness of straight edges and lines. High-quality squares are precision made to form a perfect 90-degree right angle, against which you can test all manner of edges, planes and corners on a workpiece.
