Moore and Wright 1961M External Micrometer

The Moore & Wright 1961M External Micrometer is a precision measuring instrument designed for accurate external diameter measurement up to 25mm. This traditional micrometer combines robust construction with practical features that make it ideal for quality control, inspection work, and precision engineering applications across workshops and manufacturing environments.

Built to BS870, DIN 863/1, and ISO 3611 standards, this external micrometer features a pearl chrome plated frame with integrated insulation pads to minimise heat transfer during measurement. The tungsten carbide measuring faces deliver exceptional wear resistance and long-term accuracy, whilst the tapered bow frame design provides excellent visibility of the workpiece.

The micrometer incorporates a speeder-type ratchet for consistent measuring pressure, a locking lever to secure readings, and an adjusting key for calibration maintenance. With a 6.5mm spindle diameter and 0.01mm resolution, it delivers reliable measurements with flatness to 0.001mm, parallelism to 0.003mm, and accuracy to 0.003mm. Supplied in a protective plastic pocket case for secure storage and transport.
