90 Degree Beveled Edge Engineering Square with Wide Base
Engineers squares are often used to check and calibrate machinery. If extreme accuracy is important, buy one with a stated tolerance. It is an all metal square, consisting of a blade and stock and usually silver soldered together. The stock is thicker than the blade, allowing the stock to be placed against an edge in order to mark a right angle, and also to make it stable, There should be a small slot that has been cut into the stock. This prevents small burrs caused by filing from altering the try-squares accuracy. Dirt can also collect on metal surfaces, again the slot helps prevent measuring angles inaccurately
