Insize Micrometer Setting Standard 6311-16 16inch 1pc

These individual setting standards are precision ground steel rods used to check and set outside micrometers. Also known as setting rods, they have precision ground and lapped flat or spherical ends to ensure only single points contact either measuring face of the micrometer. Rods may be plain or have one or more insulated handles to minimize any thermal expansion from the heat from an operator’s hand.
