Why Is a Square Used
A square is used as a measurement device because it consists of two straight edges set at right angles to each other.
Carpenters and machinists utilize squares to check right angles, draw lines before cutting, and locate holes.
There are two main types of squares: carpenter’s squares and machinist squares.
Machinist squares include the precision steel square and the combination square set, which consists of a steel ruler and three attachments: center head, protractor, and square head.
In drafting, a T square is used to establish a horizontal reference on the drafting board.
Did You Know?
1. The use of squares as symbols or units of measurement can be traced back to the ancient Egyptians, who used specially constructed rods with squared ends called “corner rods” for accurate measurements in construction and land surveying.
2. The concept of a square was central to the ancient Greek philosopher Pythagoras and his famous theorem. Pythagoras believed that squares and right angles represented harmony in the universe, and his theorem showed the relationship between the sides of a right-angled triangle and the areas of the squares constructed on those sides.
3. In medieval times, squares were often used symbolically in maps and drawings to represent stability, fairness, and order. The concept of a “square deal” originated from this symbolism, suggesting a fair and equitable agreement or arrangement.
4. The ancient Chinese recognized the square as a fundamental shape representing the four cardinal directions: North, South, East, and West. This concept was incorporated into various aspects of their culture, including architecture, astrology, and the practice of Feng Shui.
5. Squares have a long history in art and design, with many famous artists utilizing the shape in their work. One example is the Dutch painter Piet Mondrian, who became known for his iconic paintings with geometric compositions consisting of colored squares and rectangles. His style, known as “De Stijl,” had a significant impact on abstract art and influenced various artistic movements.

- Additionally, squares are used to determine the levelness of surfaces and the vertical alignment of walls, providing stability and balance to the overall structure.
For machinists, squares play an indispensable role in the manufacturing process. Whether in metalworking or precision engineering, squares are essential for creating precise angles and dimensions. Machinists rely on squares to check the accuracy of right angles, making sure that parts fit together flawlessly.
- They also use squares to align milling machines and drill presses, guaranteeing that holes are precisely located and centered.
Overall, squares are indispensable tools for both carpenters and machinists, contributing to the quality and strength of their finished products.
Types Of Squares: Carpenter’s Square Vs Machinist Square
Within the realm of squares, there are two main categories: carpenter’s squares and machinist squares.
Carpenter’s squares, also known as framing squares, are typically made of wood, steel, or aluminum. They consist of two arms, one longer than the other, forming a right angle. Carpenter’s squares are commonly used for large-scale construction projects, such as framing houses or building outdoor structures. They are durable, easy to handle, and provide a reliable reference for establishing right angles.
On the other hand, machinist squares are specifically designed for precise measurements in machining and metalworking applications. The precision steel square is a common type of machinist square, constructed with high-quality steel. It offers exceptional accuracy and is essential for aligning workpieces, setting up machines, and checking the perpendicularity of surfaces.
Another type of machinist square is the combination square set, which consists of a steel ruler and three attachments: the centre head, protractor, and square head. This versatile tool provides the machinist with the ability to measure, mark, and layout with precision and ease.

Precision And Versatility: The Combination Square Set
The combination square set is a true gem in the realm of squares, providing both precision and versatility to the machinist. The steel ruler, typically graduated in both metric and imperial measurements, allows for accurate linear measurements. The centre head attachment is invaluable for drawing diametral lines on cylinder ends and locating the center of circular objects. The protractor attachment can be set at any angle relative to the ruler, making it ideal for measuring and marking angular cuts or shapes. Lastly, the square head attachment, with two surfaces set at right angles and two surfaces set at 45 degrees, enables the machinist to establish and check right angles quickly and conveniently.
The combination square set offers the machinist a tool that meets multiple needs, reducing the need for multiple tools and enhancing efficiency. Its precision and versatility make it an indispensable companion in a machinist’s arsenal, ensuring accuracy and consistency throughout the manufacturing process.
