Graduation 0.001 Inch Manual Small Micrometer Head Range 0 To 0.25 Inch Hardened Ground Head Anvil Clamp Nut Quick Easy Adjustment
This micrometer head features a measurement range up to 13mm with a total length of 61mm. The carbide-tipped spindle provides exceptional flatness, accuracy, and durability. The ratchet thimble mechanism ensures even, constant measurement force.
As an adjustable positioning device, this micrometer head enables precise adjustments down to micrometer-level accuracy. The differential mechanism uses gear principles to convert rotational motion into precise linear movements, allowing exact control of minute distances.
Customization services are available for special applications, including custom spindle tips and precision lead screws manufactured to your specifications.
