Mitutoyo 250-312 Series 250 Digit Micrometer Head, 0-1"

Features:

• Mic head has a 18mm / .71" thimble diameter
• Spindle range is 25mm / 1"
• Spindle diameter 6.35mm / .25"
• Spindle pitch is 0.5mm / .0197" per rev
• Mic head total length (at stroke end) mm / 6.33"
• Flat spindle faces are constructed of carbide and have lapped surfaces for more accurate measurements over time
• Scale is laser etched for easier reading with a hard chrome plating surface that resists corrosion

The mechanical digit counter on the Mitutoyo Series 250 micrometer head displays spindle displacements numerically that is easy to see when working. The micrometer's ratchet stop mechanism provides a constant measuring force on the spindle to ensure accurate, repeatable measurements. The combination of the ratchet thimble and speeder enables a rapid spindle feed when measuring widely different dimensions and easier one-handed measurements.
