Mitutoyo 125-120 125 Series Screw Thread Micrometer, 75 to 100 mm range 5.5 to 7 mm/3.5 to 4.5 TPI screws

Description

The Mitutoyo 125-120 125 Series Screw Thread Micrometer is a vernier-style micrometer designed to measure the pitch diameter of metric and unified screw threads. It features a 60° V-anvil and a conical spindle for accurate and repeatable measurements.

Key features

• Measures pitch diameter: The micrometer is designed to measure the pitch diameter, which is the effective diameter of a screw thread. This is a critical measurement for ensuring proper thread fit.
• 60° V-anvil and conical spindle: The specific 60° shape of the V-anvil and conical spindle allows the micrometer to seat accurately in the thread grooves, ensuring smooth and reliable measurements.
• Fixed anvil type: The 125-120 is a fixed-anvil micrometer, which means the anvil is not interchangeable. This design offers durability and stability for its specific thread range.
• Ratchet stop: The ratchet stop provides a constant, uniform measuring force. This prevents overtightening and helps ensure consistent, repeatable results between measurements and different users.
• Standard bar: A standard bar is included with the micrometer for setting the zero point. This allows for precise calibration and adjustment for accurate measurements.
• Satin-chrome finish: The thimble and sleeve have a satin-chrome finish. This reduces glare from lighting, making the vernier scale easier to read.
• Durable build: The micrometer features hardened steel measuring faces for durability. The frame has a baked enamel finish to protect it from wear and tear.
• Included case: The micrometer is supplied in a fitted plastic case for protection and safe storage.
