The MITUTOYO 101306 is a lug drop indicator back designed as a replacement or alternate-mount back for dial indicators. It fits AGD Group 2 dial indicators and is used when the original back must be swapped out for a specialized mounting or application requirement. The lug-style back provides a fixed mounting point that suits setups where a standard flat back cannot be used. Metrology technicians, machinists, and quality control professionals install this component when configuring indicators for surface plate work, machine tool setups, or fixture-based inspection routines.
This indicator back is intended for use with AGD Group 2 dial indicators. It is a direct replacement for worn, damaged, or application-incompatible backs on existing indicators. Typical installations include precision measurement setups in manufacturing, toolroom, and quality assurance environments where the indicator must be mounted in a fixed orientation using a lug attachment point.
Designed for use with AGD Group 2 dial indicators requiring a lug drop back configuration.
Installation is typically performed by a machinist or metrology technician during indicator servicing or setup. Power down or de-energize any associated machine tool or fixture before working on mounted indicators. Handle precision indicator components carefully to avoid damage to mating surfaces or threads. Verify that the replacement back is fully seated and secure before returning the indicator to service.
