This Werka professional outside micrometer is a high-precision measurement tool designed for accurate dimensional measurements. With a measurement range of 0-1 inch and ultra-fine graduations of 0.0001 inch, it provides exceptional accuracy for critical measuring tasks. The micrometer features a robust construction with a hammered finish frame for durability and stability during use. Its thimble and sleeve are clearly marked with precise graduations for easy reading, while the spindle and anvil faces are carefully machined to ensure measurement accuracy. The ratchet stop mechanism helps maintain consistent measuring pressure, preventing over-tightening that could affect readings. The lock nut allows measurements to be preserved for reference. This precision instrument is ideal for machinists, toolmakers, quality control professionals, and anyone requiring highly accurate measurements in manufacturing, engineering, or inspection applications.
