Starrett 71843 Micrometer Rod 6 Inch 449 Series Depth Gages

Product Description

The STARRETT 71843 is a replacement micrometer rod accessory designed for use with 449 Series Micrometer Depth Gages. This rod-type anvil extension allows technicians and machinists to expand the measurement range of their depth gage setup. With a maximum measurement capacity of 6 inches, the 71843 provides reliable, repeatable depth readings in precision measurement applications. It is a direct-fit accessory intended for professionals who require accurate depth gauging across a variety of bore, slot, and step measurement tasks in manufacturing, inspection, and tool-and-die environments.

This micrometer rod is suited for use in machine shops, quality control departments, and fabrication facilities where the 449 Series Micrometer Depth Gage is already in service. The rod design allows for straightforward extension of the gage's measurement range, making it practical for deeper bore or stepped-surface inspections. Dimensional accuracy is critical in these environments, and this rod is built to maintain the precision expected of depth gage tooling in production and inspection settings.

Installation Notes

Installation of this micrometer rod should be performed by a qualified machinist or metrology technician familiar with depth gage assembly. Ensure the depth gage is removed from service and not under load before swapping or attaching rod extensions. Follow the 449 Series Micrometer Depth Gage manufacturer instructions for proper rod seating and lock-down procedure to maintain measurement accuracy. Avoid overtightening any clamping mechanism, as this can affect gage calibration.
