Starrett 68005 Mechanical Outside Micrometer 2 in

Product Description

The STARRETT 68005 is a mechanical outside micrometer designed for precise linear measurement in trade and industrial applications. It delivers a measurement range of 2 inches with a graduation of 0.0001 inches and an accuracy of 0.000050 inches, making it suitable for exacting dimensional inspection work. The ratchet stop thimble ensures consistent measuring pressure on every reading, reducing operator error. Measuring faces are solid carbide for long service life. A satin chrome finish resists corrosion in shop environments. This tool is used by machinists, pipefitters, HVAC technicians, and fabricators who require reliable outside diameter and thickness measurements.

The STARRETT 68005 is suited for residential and commercial mechanical, HVAC, and fabrication environments where accurate outside measurement of parts, tubing, shafts, or fittings is required. The 2-inch range covers a wide variety of standard component sizes encountered in service and manufacturing work. The ratchet stop thimble and ring-style lock nut make single-handed operation straightforward during field or bench service. No digital counter or rotating spindle is included, keeping the instrument simple and reliable.

Installation Notes

Outside micrometers are handheld precision instruments and do not require installation. Handle with care to avoid dropping, which can affect calibration. Clean measuring faces with a lint-free cloth before and after use. Store in the provided case away from temperature extremes to maintain accuracy. Periodic calibration against a certified gauge block is recommended per standard metrology practice.
