Sealey External MicroMetre Set (3)

The Sealey External Micrometer Set (3) is a precision measuring set designed for accurately measuring the outside dimensions of components, shafts, pins, bushes and other machined parts. The set contains three metric external micrometers covering measurements from 0 to 75 mm, providing a practical range for general engineering, machining, automotive and workshop applications.

Each micrometer features a steel yoke, satin chrome finished thimble and sleeve, machined grip surfaces and a locking mechanism to help secure measurements during inspection.

IMPORTANT INFORMATION

Micrometers should be handled carefully and kept clean to maintain accurate measurements. Before taking a measurement, ensure the measuring faces and component are free from dirt, swarf and other material that could affect the reading.

Store the micrometers in the supplied case when not in use and avoid excessive force when closing the measuring faces. For critical measurements, ensure the instrument is correctly calibrated and used in accordance with good workshop measuring practice.
