The Mitutoyo hub micrometer is designed for precise measurements of hub thickness and shoulder inside a bore.
Features & Benefits
The Mitutoyo hub micrometer features high-grade hardened steel on its frame, spindle and anvil to deliver precise, repeatable thickness and shoulder measurements. The micrometer’s ratchet-stop mechanism provides uniform pressure on a workpiece for precise, repeatable measurements. An inch Vernier scale provides outside diameter measurements.
- Available in Metric and Inch models
- Measuring surfaces on the anvil and spindle are constructed of carbide to reduce wear
- Ratchet mechanism provides an audible click to ensure measurement is performed at a constant force
- Satin chrome finish on the sleeve and laser etched measurements on thimble for easier reading
- Frame has a baked enamel finish for durability and longer lifespan
- Includes a standard bar except for 0-25mm / 0-1” model
- Supplied in fitted plastic case
