Brown & Sharpe TESA 74.108942 Reducing Sleeve for Dial Test Indicator, Metric

Dial test indicator gauges, also called gages, are precision instruments that measure short linear distances. They are commonly used for detecting deviations from tolerance limits, such as small variations in flatness or height of an inspected workpiece, and permit measurement in narrow grooves or small bores. A dial test indicator gauge consists of a ball-tipped contact point on a levered arm, also called a measuring insert, which pivots from a hinge point. The dial indicates the degree of angular displacement of the arm. Dial test indicator gauges are commonly used in manufacturing, machining, and mechanical engineering.
