This is a great option for design engineers as it is incredibly accurate, but all engineers would benefit from investing in this combination square.

The Johnson’s Johnny square is clear to read and an easy tool to use. It is an excellent option for engineers who use saws, drills or other tools that require measurements on a daily basis. It is made from aluminium and glazed to prevent any glares that prohibit the user from incorrectly measuring or making a measurement. The measurements are etched into the surface of the square, which also maintains optimum visibility. 

The edges of the square are created by a CNC machine, which gives them high accuracy. One edge is especially thick to act as a saw guide when cutting a piece of wood or other material. The square is made from aluminium, which is very durable and long-lasting. This square will give you precise results for years or even decades. For an engineer having a precise and accurate square is a must-have when using power tools. The Johnson’s Johnny square is an excellent option for every engineer.

For any engineer that is looking to invest in a set of squares, then the Groz 3-Piece machinist squares are a perfect choice. Within the set are three different-sized squares; 2-inch, 4-inch and 6-inch. They are fabricated from polished, high-quality steel, meaning they will last a very long time. Like the Swanston, this set comes with an instructional manual to ensure the engineer understands the optimum way to use these tools to get the best results. 

The blade and stock are ground which ensures incredible accuracy. These squares even adhere to BS 939 Grade B accuracy standard, which ensures that the measurements detailed on these tools will always be within 16 microns or 0.00063 inches. This high accuracy is due to how Groz involves extreme care within its manufacturing process. The only issue is that some customers have found that the pins that hold the base and the blade together can get loose over time. But overall, this is an excellent set for any engineer looking to invest in a square set.
