About Protractors & Machinist Squares

Protractors & Machinist Squares are tools used to measure angles and dimensions, often in the manufacturing and engineering industries. They can be used to check the accuracy of machined parts or to create precise layouts on a variety of materials.

Types of Protractors & Machinist Squares

Protractors come in many shapes and sizes, from small handheld models to large industrial-grade tools. Some protractors are adjustable for more accurate measurements, while others have fixed blades that allow for faster readings. Machinist squares also vary in size and shape, with some featuring extra features like scribed lines or a built-in level.

How Protractors & Machinist Squares are Made

Most protractor tools are made from stainless steel or hardened steel alloys that provide strength and durability. Many machinist squares are constructed from aluminum alloy due to its lightweight nature and corrosion resistance. Both types of tools typically feature precision etched markings that help ensure accuracy.

Industries that use Protractors & Machinist Squares

Protractor & machinist squares are used across many industries including automotive repair, woodworking, metal fabrication, electrical engineering, HVAC installation, and general construction. Professionals rely on these tools to accurately measure angles and dimensions quickly when working with complex projects.
