Slide ruler calipers take precise inside and outside measurements with a moveable jaw that travels along the ruler.

Measuring squares consist of two straight edges set at a 90-degree angle to each other. The primary purpose of these measuring tools is to check the accuracy of right angles to ensure that components remain perpendicular. Similarly, protractors are a measurement device used to measure angles.

Thickness gauges are used to measure the thickness of sheet metals, pipe, tubing, wire, and other materials.
