Precision Rules & Squares provide accurate measurements in various workshop applications. Precision squares, also called machinist squares and engineer's squares, consists of two blades welded or pinned at a 90-degree angle. They are used as a guide to ensure corner joints of workpieces are perfectly perpendicular. Precision rules are basic measuring tools for linear distance. They are commonly made from steel with etched measurement markings for strength and durability.
