Framing-Square

A framing square, also known as a steel square or carpenter’s square, is an essential hand tool in construction and woodworking used to measure, mark, and verify angles, especially 90-degree (right) angles. Made of metal for durability and precision, it is commonly used for framing walls, laying rafters, stair building, and general layout work. Its long arm (blade) and shorter arm (tongue) make it ideal for creating straight, square lines and accurate cuts in carpentry tasks.
