Mitutoyo 102-702 Mechanical Outside Micrometer

Product Description

The MITUTOYO 102-702 is a mechanical outside micrometer designed for precise external dimensional measurement in manufacturing, machining, and inspection environments. It features a 0.01 inch graduation and delivers an accuracy of 0.0001 inches, making it suitable for close-tolerance work. The thimble uses a ratchet stop mechanism to apply consistent measuring force, reducing operator-induced error. Both the anvil and measuring face are solid carbide for long-term wear resistance. The frame includes heat-insulating panels, allowing extended handling without thermal expansion affecting measurement accuracy. Machinists, quality control technicians, and tool and die professionals are the primary users of this instrument.

The 102-702 is used in precision measurement applications across machine shops, fabrication facilities, and quality inspection stations. It is suited for both production-floor spot checks and formal inspection workflows. The spindle diameter is 6.35 mm with a throat depth of 30.00 mm, providing clearance for a range of workpiece profiles. The instrument is packaged with a plastic case for storage and transport protection, and ships with a proprietary inspection certification.

Key Features

Compatibility

Designed as an OEM-style precision measuring instrument for use in general machining and inspection applications requiring mechanical outside micrometer capability.

Installation Notes

This instrument requires no installation and is used as a handheld measuring device. Before use, verify zero calibration against a known reference standard and clean both measuring faces with a lint-free cloth. Store in the included plastic case away from heat sources and contaminants. Calibration should be performed at regular intervals per your facility quality management procedures.
