0-0.25" Range Small Micrometer Head with Clamp Nut Hardened and Ground Head Anvil Quick and 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.

Applications

Optics: Used in production and inspection equipment for DVD, MD, and CD reading lenses, as well as writable optical heads
Liquid Crystal Projection: Critical for prismatic positioning and film loading processes to ensure image clarity
Fiber Optic Technology: Ensures accuracy in manufacturing and testing equipment for optical communication systems
LCD Production: Used in display manufacturing processes for high-precision equipment adjustment
Semiconductor Industry: Widely used in production and inspection equipment to ensure process accuracy
Mechanical Engineering: Essential for machine tool adjustment, precision tools, and special gauges requiring micrometer-level accuracy

Precautions

Perform precise calibration before use by verifying repeatable readings within 1/10 of the range
Select appropriate measurement range (0-5mm, 0-6.5mm, 0-13mm, 0-15mm, 0-25mm or 0-50mm) to ensure measurement precision
Maintain micrometer head perpendicular to measurement object
Ensure stable contact with measured object before taking readings
Read measurements vertically to avoid angle-induced deviations
