Starrett 68126 Mechanical Micrometer 0.16 in Ratchet Stop

Product Description

The STARRETT 68126 is a mechanical micrometer designed for precision measurement in toolroom, machining, and inspection applications. It measures to a maximum range of 0.16 inches with a graduation of 0.0001 inches and an accuracy of 0.0001 inches, making it suitable for high-tolerance work where reliable, repeatable readings are critical. The ratchet stop thimble provides consistent measuring pressure, reducing operator-to-operator variation. Measuring faces are solid carbide for wear resistance during extended production use. This instrument is intended for use by machinists, metrology technicians, and precision manufacturing professionals.

The 68126 is suited for precision dimensional inspection in manufacturing, toolroom, and quality control environments. Its compact measuring range and fine graduation make it appropriate for gauging small-diameter features, bores, or components requiring close-tolerance verification. The micrometer accommodates extension rods up to 6 inches in length, expanding its reach for deep or recessed measurement applications. It ships with a case, contacts, a setting ring with a 0.16-inch diameter, and wrenches, providing a complete ready-to-use package for bench or field inspection work.

Compatibility

Designed as an OEM-style precision measuring instrument for toolroom, inspection, and machining applications requiring a 0.16-inch maximum range mechanical micrometer with ratchet stop thimble.

Installation Notes

This instrument should be handled and stored by a qualified metrology technician or machinist. Before use, verify the micrometer zero with the included setting ring and calibrate as needed per shop or ISO calibration procedures. Avoid dropping or subjecting the micrometer to impact, which can affect accuracy. Store in the provided case when not in use to protect the carbide measuring faces and maintain calibration.
