Starrett 55213 Micrometer Case 232 232M Outside Micrometers

Product Description

The STARRETT 55213 is a replacement protective case designed for outside micrometers with a maximum measuring range of 0.5 inches. Constructed from steel and vinyl, it provides durable storage and protection for precision measuring instruments between uses. This case is an accessory item intended for use by machinists, metrologists, HVAC technicians, and other trade professionals who rely on outside micrometers for accurate measurement work. Keeping a micrometer properly housed prevents damage to the anvil, spindle, and thimble surfaces that would compromise measurement accuracy.

This case is matched to the 232 and 232M Series Outside Micrometers from STARRETT and is suited to shop, field, or service van environments where precision tools need secure, dedicated storage. It fits the standard 0.5-inch measuring range instruments in that product family and is sold individually.

Installation Notes

No installation is required for this accessory case. Before storing the micrometer, ensure the spindle is backed off to relieve clamping pressure on the anvil faces, which helps preserve calibration. Inspect the interior of the case periodically for debris or moisture that could damage the instrument. Handle the case and instrument together according to applicable shop metrology procedures.
