Mitutoyo 103-181 Series 103 Outside Micrometer with ratchet stop, 4 to 5", 0.001"

Description

The Mitutoyo 103-181 is a standard, inch-unit outside micrometer designed for precise measurement of outside diameters between 4 and 5 inches. The vernier scale provides a graduation of 0.001", and it is equipped with a ratchet stop for consistent, repeatable pressure.

Key features

• Precise measurements: It has a 4-to-5-inch range with a graduation of 0.001 inch and an accuracy of $\pm$0.00015 inch, making it suitable for applications requiring high exactitude.
  
• Ratchet stop: This mechanism ensures consistent measuring pressure on the workpiece, which is critical for repeatable results. Once the right pressure is applied, it clicks to prevent over-tightening or damage to the object being measured.
  
• Carbide-tipped measuring faces: The anvil and spindle are tipped with carbide, which offers superior wear resistance. This keeps the measuring faces flat for longer and maintains the micrometer's accuracy over time.
  
• Spindle lock: A locking nut is included to secure the spindle at a specific position, which holds the measurement in place. This is useful for taking a reading after the micrometer has been removed from the workpiece.
