The Moore & Wright 1966M/50 External Micrometer is a precision measuring instrument designed for accurate dimensional measurement in engineering and metalworking applications. Part of the respected 966 Series, this traditional micrometer features a durable blue textured frame finish combined with tungsten carbide measuring faces for extended service life and wear resistance. The micrometer incorporates a speeder-type ratchet mechanism that enables rapid spindle adjustment whilst maintaining consistent measuring pressure, ensuring repeatable accuracy across multiple measurements. A locking lever secures measurements in place for easy reading, whilst the included adjusting key allows for calibration maintenance. The 6.5mm spindle diameter provides robust construction suitable for workshop environments. Manufactured to BS870, DIN 863/1 and ISO 361 standards, this micrometer delivers professional-grade accuracy essential for quality control, machining verification and engineering inspection tasks. The 25-50mm measuring range with 0.01mm graduation makes it ideal for checking shaft diameters, material thickness and component dimensions where precision is critical.
