Need a tool that will quickly and accurately measure the dimensions of small components? Thanks to its resolution of 0.0001 in, this external micrometer from RS PRO is ideal for precision engineering work. As its measuring faces are made from highly durable carbide, the faces won't chip and cause inaccurate readings. The easy-to-use thimble on the micrometer features a knurled surface that provides excellent grip with or without gloves. There's a ratchet stop at the thimble's end to guarantee repeatable measures, which saves time when you need to measure multiple objects of the same size. As part of the RS PRO range, this product has been tested by engineers for quality and reliability. You'll commonly find this type of micrometer used in manufacturing operations as a quality control instrument.
