Spi CMS160622009 Outside Micrometer Set 6-12 in 6 Pc

Product Description

The SPI CMS160622009 is a 6-piece mechanical outside micrometer set covering a measurement range of 6 to 12 inches. Each micrometer in the set features a ratchet stop thimble for consistent measuring force and a rotating spindle for smooth operation. Accuracy is rated at 0.0002 to 0.0003 inches across the range, making this set appropriate for precision measurement tasks in machining, fabrication, and quality control environments. The instruments carry an enamel finish and come calibrated with NIST traceability certification included. Machinists, toolmakers, and metrology technicians are the primary users of this set.

This micrometer set is suited for shop-floor and inspection room use where large-diameter external measurements are required. The 6-to-12-inch range makes it practical for measuring large shafts, bores, castings, and fabricated components in industrial and manufacturing settings. Each piece in the set addresses a distinct 1-inch interval within that range, providing full coverage without switching instrument families. The NIST-traceable calibration documentation supports quality management systems and audit requirements.

Compatibility

Designed as a general-purpose outside micrometer set for precision measurement of external dimensions in the 6 to 12 inch range in industrial and manufacturing applications.

Installation Notes

Outside micrometers require no installation but should be handled and stored carefully to preserve calibration. Keep instruments in their case when not in use and avoid dropping or subjecting them to impact. Verify calibration against a known standard before use, particularly after transport or extended storage. Recalibration should be performed by a qualified metrology technician if readings fall outside expected accuracy tolerances.
