Starrett 254Z-18 Master Vernier Height Gage

The Starrett 254Z-18 is a height gauge with a Vernier scale, a hand-operated slider, a grip-base design, a rust-resistant, satin chrome finish, a measurement range of 0 to 18", and is precise to 0.001". The adjustable 50-division Vernier scales are flush fitting to the main scale to eliminate parallax. Black lines and figures against the satin chrome finish eliminates glare and eases reading. The included scriber, used to mark position on the workpiece, is steel for hardness and durability. The scriber and base are designed for direct reading from zero (bottom of base). A quick-adjust release on the slide allows for fast positioning. A fine adjustment knob on the base isolates the column and slide from external pressures. The master bar is hardened and stabilized and the balanced design and weight of the base eliminates vibration. The base is hardened, ground, and lapped square with the bar and has finger grooves to provide ease of movement. The vertical bar is positioned near the center of the base for balance and stability. The tool will scribe lines, mount dial indicators, or electronic probes, and accept depth attachments (sold separately). The gauge comes with a case. Height gauges, sometimes referred to as gages, are precision measuring instruments that travel on a vertical column (also called the beam) to measure and/or mark the vertical distance from the base of an object in fine units. The vertical position of the gauge and its attached pointer are changed by turning a calibrated screw, or one or more feed wheels. Recorded rotations are read from a scale, a dial, counters, and/or an electronic display. A screw clamp holds the pointer to the gauge. The pointer is typically sharpened to act as a scriber, and can be used to mark a position on a workpiece by scratching its surface. On compatible units, the scriber may be replaced by an electronic touch-signal probe. Height gauges are typically used in manufacturing, machining, and mechanical engineering. The L.S. Starrett Company manufactures precision measuring tools, metrology and testing equipment, and saw blade products. The company was founded in 1880 and is headquartered in Athol, MA.
