a measuring and marking tool with a straight edge and a perpendicular arm, typically made of steel, used in carpentry and construction for checking right angles and laying out accurate measurements
A steel square, also called a framing square, is a flat, L-shaped tool used in construction and woodworking for measuring and marking right angles, as well as for layout and cutting tasks. It consists of two straight edges joined at a 90-degree angle, with one longer side called the blade and a shorter side called the tongue. The tool has measurement markings along both sides, allowing for precise measurements and angle calculations. Steel squares are commonly used for tasks like framing, roofing, and stair building, ensuring accuracy in creating straight and angled cuts.
