Mitutoyo 148-112-10 Micrometer Head 0-0.5 in Flat Spindle

Product Description

The MITUTOYO 148-112-10 is a replacement micrometer head with a measuring range of 0 to 0.5 inches and a graduation of 0.001 inches. It features a flat spindle face and a plain thimble design, making it suited for precision measurement applications where a bare head is integrated into a custom fixture, gauge stand, or OEM instrument. The spindle is rotating and the measuring face is constructed from steel. Accuracy is rated at plus or minus 0.0001 inches. Machinists, metrologists, and precision instrument technicians use this head as a drop-in component in custom or production measurement setups.

This micrometer head is intended for integration into fixtures, automated gauging systems, or custom-built measurement tools in machine shops, tool rooms, and quality control environments. It ships as a single unit without extension rods or a clamp nut. The plain thimble and flat spindle configuration suits applications where direct contact with a flat workpiece surface is required and no thimble locking mechanism is needed at the head level.

Key Features

• Measuring range: 0 to 0.5 inches
• Graduation of 0.001 inches with accuracy to plus or minus 0.0001 inches
• Flat spindle face for direct contact with flat workpiece surfaces
• Plain thimble — no ratchet or friction thimble mechanism
• Rotating spindle design
• Steel measuring face for durability in production environments
• No digital counter — analog graduation reading

Compatibility

Designed as a replacement or integration micrometer head for precision fixtures, gauging systems, and custom measurement instruments requiring a 0 to 0.5 inch range flat-spindle head.

Installation Notes

Installation of this micrometer head is typically performed by a machinist or metrologist integrating the component into a fixture or gauge assembly. Ensure the mounting bore and thread engagement match the head specifications before installation. Handle the spindle and measuring face carefully to avoid nicks or contamination that would affect measurement accuracy. Calibrate the assembled instrument after installation before taking measurements.
