Clamps are fastening tools that use pressure to secure workpieces to each other or to a workspace, and prevent movement. Clamp style varies widely, depending on general and specialized applications. Many clamps are for temporary use during construction, repair, or alignment of a workpiece, while others may be used to secure a component in its final installation or assembly.
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.
