Mitutoyo 3424S-19 Dial Indicator, #4-48 UNF Thread, 0.375" Stem Diameter

For measuring surface fluctuations in fractional inches, this standard dial indicator has a 0.375" diameter stem, a #4-48 UNF contact point thread mount, and a choice of white or black face. It includes a rotating bezel and limit markings, and it displays units in fractional inches. For a choice of mounting possibilities, choose between flat or lug back. The stem design allows for a wide clamping range, no through screw holes on the frame for dust and water resistance, and an involute curved lifting lever for smooth movement of the spindle and dovetail junction for toolless connection. Face and thread size, as well as bezel and stem diameter, meet ANSI, Japanese Industrial Standard (JIS) B7503-1997, and American Gage Design (AGD) criteria. Product Dimensions (cm): 32.26 x 10.16 x 7.87   The Mitutoyo dial indicator features a black or white face, a flat or lug stem, a 0.375" stem diameter, and an inch measurement. The choice of a black or white dial and a contrasting hand aid in reading measures. For a range of mounting choices, the dial indicator comes with a flat or lug back. Flat back dial indicators are either clamp-mounted on the stem or plate-mounted on the back. Lug back dial indicators have a protrusion with a hole through which the indicator may be mounted with a lug or nut and bolt. The lug on lug back dial test indicator is normally positioned horizontally. Most indicators' backs may be turned to a vertical position. It has a stem design with a large clamping range, no through screw holes on the frame for dust and water resistance, and an involute curved lifting lever with smooth movement of the spindle and dovetail junction for a tool-free connection. For face and thread size, as well as bezel and stem diameter, this dial indicator fulfills ANSI, Japanese Industrial Standard (JIS) B7503-1997, and American Gage Design (AGD) criteria. Three-digit dial readings, such as 0-10-0, indicate that the indicator has a balanced dial. Dial readings that contain two digits, such as 0-100, imply that the dial is continuous. Balanced dials are used to read the difference between two points on a surface. Continuous dials are used for direct measurements and offer a wider measuring range than balanced dials. Jeweled bearings for high sensitivity and precision, a revolution counter to monitor overall change, waterproof, dustproof, shockproof, a white or black face, and reverse reading for depth or bore gauge measurement are all optional features. Dial gauges, dial calipers, and probe indicators are other names for dial indicators. These precision measuring instruments are used to measure tiny linear distances and item sizes precisely. The dial amplifies the measurement, making it easier to read with the naked eye. Dial indicators are commonly used in manufacturing, labs, and other industrial or mechanical domains when a tiny measurement must be detected, recorded, or conveyed, such as when monitoring the variation in tolerance of a workpiece. Standard dial indicators detect displacement along the indicator's axis. Dial test indicators are quite similar to dial indicators, with the exception that the axis of measurement is perpendicular to the indicator's axis. Dial and dial test indicators can be either analog (mechanical dial) or electronic (digital display). Some electronic models electronically convey data to a computer for recording and future modification.
