Overview
The Starrett No. 63 micrometer head is a precision fixture-mounted measuring instrument designed for integration into gaging and machine tool setups. This used unit combines the renowned Starrett measurement standard with an i2 New England Affiliated Technologies mounting head for flexible installation. The 0-2″ range with .0001″ graduation provides repeatable accuracy across a wide range of dimensional checks common in job shops, tool rooms, and manufacturing environments.
Key Features
- Long-range measurement: 0-2″ range with .0001″ graduation for fine resolution work
- Ratchet stop mechanism: Ensures repeatable, consistent measurement force and prevents over-tightening
- Lock nut design: Holds the measured value in place for hands-free reading and documentation
- Carbide contacts: Durable measuring surfaces resist wear and maintain accuracy through extended use
- Vernier scale: Long spindle travel allows direct reading to .001″ with vernier capability for .0001″ resolution
- Fixture-ready stem: Plain stem design accepts mounting in clamps, fixtures, or custom assembly configurations
