Fowler 52-526-333 Cold Rolled Steel with Black Oxide Plating Indic...

The Fowler 52-526-333 Indicator Point Extension Kit includes three indicator points that have 4-48 UNF internal and external threads, are constructed of cold-rolled steel and black oxide plating, and are designed to extend the reach of standard indicator contact points. The kit includes one each of 1", 2", and 3" indicator point extenders that are designed for use with dial, electronic and test indicators and indicator points that have a 4-48 UNF threads. The extenders are made from cold-rolled steel and have a black oxide plating that provides durability and rust-resistance.

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 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 reading indicates the degree of angular displacement of the arm. Test indicator gauges are commonly used in manufacturing, machining, and mechanical engineering. Standard test indicators measure the displacement of the arm perpendicular to the axis of the indicator. Dial and electronic indicators are very similar to test indicators, except that the axis of measurement is parallel to the axis of the indicator. Test indicators can be analog, with a mechanical dial, or electronic, with a digital display. Some electronic models transfer the data electronically to a computer for recording and potential manipulation.

The Fred V. Fowler Company manufactures inspection and measurement instruments such as electronic indicators, calipers, bore gages, and digital scales. The company, founded in 1946, is headquartered in Newton, MA.
