Engineers squares, also called machinist or precision squares, are essential hand tools for engineers, machinists, and craftsmen to mark and check accurate right angles and straight edges in their work. These squares are specialised measuring instruments with a flat, straight and perpendicular edge, forming a 90-degree angle. These L-shaped metal tools are typically made from hardened or tool steel materials, ensuring precise accuracy with robust accuracy and durability in the long run.
Furthermore, an engineer square comes in various types, with a combination square being the most common type. This square comprises a steel blade with a scale/ruler and perpendicular stock at either end. The integrated stock slides along the blade for setting the required angle or measurement. Additionally, professional engineers squares are a preferred choice for various carpentry and metalworking applications, among others.
Engineers Square vs Try Square: The Key Differences
Engineers and try squares are both angle measurement and marking tools with almost similar functions. However, they differ slightly based on their material construction, accuracy, and integration of grooves or relief. Engineers squares are entirely made of hardened steel compared to try squares made of wood. Moreover, try squares do not feature as much accuracy as edge squares. Additionally, engineers squares feature grooves or relief, while try squares do not feature.
Engineers Square Set: The Importance
Engineers squares can be found in a highly precision engineer square set that comprises various squares of multiple sizes, numbers, and other related tools. These engineers square sets offer various benefits in terms of packing numerous tools in a single package. These sets are also beneficial for engineers to carry out different tasks on the go instead of carrying individual tools, thus reducing time and effort.
Typical Applications and Functions of Engineers Squares
Engineers squares find applications in woodworking, metalworking, fabrication and welding, and other engineering tasks with various functions, such as:
- Checking Right Angles – These squares are used to verify the perpendicularity of surfaces or structures.
- Marking Straight Lines – Engineers squares provide a reliable guide for drawing straight lines or scribing marks.
- Setting Up Tools & Machinery: These marking and measuring squares help ensure the proper alignment of workpieces, tools, and machines.
- Measuring & Layout: Bespoke squares can serve as measuring instruments for accurate length and depth measurements.
- Checking Flatness: Mechanistic squares can determine the surface flatness by comparing it against the straight edge.
