Mitutoyo 126-143 Screw Thread Micrometer Interchangeable Tips, 6 to 7”

Description

The Mitutoyo 126-143 Screw Thread Micrometer is a 6-7" vernier micrometer designed for measuring the pitch diameter of screw threads. It is an analog model that requires optional, interchangeable V-anvil and conical spindle tips to function. 

key features

• Interchangeable measuring faces: The micrometer's main feature is its ability to use interchangeable V-anvil and conical spindle tips, which are sold separately. This allows for the measurement of various thread diameters and pitches, including Unified (60°) and Whitworth (55°) threads.
  
• Direct pitch diameter measurement: The tool provides a direct reading of the screw thread's pitch diameter without requiring additional calculations.
  
• Ratchet stop: A ratchet-stop mechanism applies a constant and uniform force to the workpiece during measurement. This is crucial for obtaining consistent and repeatable readings.
  
• Spindle lock: The micrometer is equipped with a spindle lock that secures the spindle after a measurement is taken to preserve the reading.
  
• Vernier scale: The micrometer has a vernier scale on its thimble and sleeve for precise outside diameter (OD) measurements.
  
• Heat shield: The frame is built with an integrated heat shield to protect the instrument from errors caused by body heat affecting the temperature of the micrometer.
  
• Protective finishes: The thimble and sleeve have a satin chrome finish for easy reading, while the frame features a durable baked enamel finish.
  
• High-grade materials: The construction uses high-grade steel to ensure long-term durability and stability.
