Mitutoyo Mechanical Screw Thread Micrometer

The Mitutoyo Mechanical Screw Thread Micrometer is a precision hand-held measuring tool for checking the pitch diameter of external screw threads. It is also called a thread micrometer or screw thread micrometer. Machinists, toolmakers, and quality inspectors use it to verify thread form and size in the shop or at the inspection bench.

Key Features:

• Mechanical (non-digital) design that needs no battery and gives a direct reading from the thimble and sleeve
• Pitch diameter measurement of external threads with interchangeable thread-specific anvil and spindle inserts
• Graduated in inch units for precise, repeatable readings
• Rigid frame construction that holds measurement accuracy and stability
• Ratchet or friction thimble that helps apply consistent measuring force
• Spindle lock to hold a measurement while you read or record it
• Built by Mitutoyo, a long-established maker of precision measuring instruments
