Product Description

The STARRETT 71841 is a replacement micrometer rod designed for use with 449 Series Micrometer Depth Gages. This accessory extends the measurement capability of the depth gage, allowing accurate depth readings up to 4.0000 inches. The rod serves as the measuring anvil in the depth gage assembly, contacting the reference surface to deliver precise linear measurements. It is a direct-fit accessory for technicians and machinists who maintain, repair, or expand the range of their existing 449 Series instruments. Proper rod selection is critical to maintaining measurement accuracy in precision metrology applications.

This rod is intended for use with the STARRETT 449 Series Micrometer Depth Gages in professional machining, tooling, and inspection environments. It is suited for bench-top metrology work where depth measurement of bores, slots, counterbores, and steps is required. The rod type anvil design is standard for micrometer depth gage accessories in both production and quality-control settings.
