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.

These steel setting standard kits contain precision ground rods used to set micrometers to a specific measurement and to check that the micrometer is accurate. 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. These rods may be plain or have one or more insulated handles to minimize any thermal expansion from the heat of the operator’s hand. These sets consist of varying lengths of standards in increments of 1” or 25mm.
