Insize Stainless Steel 135° Square with Wide Base

An engineer square, also known as a machinist square, is a precision measuring tool used in engineering, woodworking, and metalworking to check the accuracy of right angles and measure flatness. It consists of a steel blade and a stock, both machined to be perfectly perpendicular. The blade is inserted into the stock and secured, forming a 90-degree angle. Engineer squares are available in various sizes, typically ranging from 2 to 24 inches. They are essential for ensuring the squareness of machine setups, checking the accuracy of cuts and joints, and maintaining precision in various fabrication and construction tasks.
