A steel square, which is also known as a framing square or carpenter's square, is a tool that is widely used in woodworking, construction, and metalworking due to its versatility. It consists of a long metal blade with markings and a shorter perpendicular blade called the tongue. These markings on a steel square have different purposes and enable accurate measurements, angles, and cuts. Here are some of the most commonly used markings and their functions:
1. Blade Length: The blade is typically marked in inches or centimeters, allowing for quick measurements of length or width.
2. Graduated Scales: These scales, found along the blade and tongue, are often marked in inches or fractions of an inch. They aid in measuring distances, marking points, and performing precise layout work.
3. Rafter Tables: These tables are printed on the blade of the square and provide information for making common rafter cuts. They assist in determining lengths, angles, and pitches for roof framing.
4. Degree Scale: Some steel squares have a protractor-like scale on the tongue, showing degrees ranging from 0 to 90. This scale is utilized to accurately measure and mark angles, particularly when framing or cutting bevels.
5. Squaring: The primary function of a steel square is to check and ensure squareness. The 90-degree angle formed by the blade and tongue allows for precise right-angled cuts, corner layouts, and the squaring of frames and structures.
6. Scribing: Certain squares are designed with a scribing notch or hole near the tip of the tongue. This feature allows the square to be used as a marking or scribing gauge, enabling the creation of parallel lines or the transfer of measurements onto a workpiece.
7. Level: Some steel squares incorporate a built-in level bubble, indicating whether a surface or object is level or plumb. This feature is useful for aligning shelves, cabinets, or other vertical or horizontal installations.
In conclusion, the various markings on a steel square facilitate measurements, point marking, angle calculation, and the achievement of accurate and precise cuts in woodworking and construction tasks. This tool's versatility has made it a favorite among carpenters, woodworkers, and DIY enthusiasts alike.

The versatility of this tool makes it a favorite among carpenters, woodworkers, and DIY enthusiasts alike.
There are several markings on a steel square that serve different purposes. The most common markings are the graduations along the blade and tongue, which are used to measure and mark lengths or angles. The numbers on these graduations indicate inches, centimeters, or degrees, depending on the type of square. Additionally, there may be markings for rafter tables, brace tables, or other construction-related calculations. These markings help carpenters and other tradespeople quickly and accurately perform various tasks, such as marking cuts or determining angles.
