Starrett 64515 Dial Caliper 6 Inch Stainless Steel

Product Description

The STARRETT 64515 is a dial caliper designed for precise dimensional measurement in professional trade and industrial applications. It provides a 6-inch measurement range with a dial graduation of 0.001 inches and an accuracy of 0.001 inches, making it suitable for tasks that require tight tolerance verification. The caliper body and jaws are constructed from stainless steel with a satin chrome finish. The black-face dial improves readability in shop lighting. Licensed machinists, pipefitters, HVAC technicians, and tool-and-die professionals rely on instruments like this for verifying component dimensions, pipe fittings, and fabricated parts before installation or assembly.

This caliper supports four measurement types: outside, inside, depth, and step measurement. The 1.5-inch jaw length accommodates a wide range of workpiece geometries. The 0.1-inch-per-revolution dial movement allows smooth, readable progression across the full 6-inch range. A protective case is included, making this instrument appropriate for field service, shop benches, and quality-control inspection points alike. It suits both residential and commercial trade environments wherever precise measurement of hardware, tubing, fittings, or mechanical components is required.

Installation Notes

Before use, verify the caliper zeroes correctly with jaws fully closed and clean any debris from the measuring surfaces. Store the instrument in the included case when not in use to protect the dial mechanism and measuring surfaces from damage. Avoid exposing the instrument to heavy impacts or dropping, as this can affect calibration accuracy. Periodic calibration against a certified gauge block is recommended for quality-critical applications.
