Spi CMS160622051 Outside Micrometer Set 6 Pc 0-150mm

Product Description

The SPI CMS160622051 is a 6-piece mechanical outside micrometer set covering a metric measurement range of 0.00 to 150.00 mm. Each micrometer features a ratchet stop thimble for consistent, repeatable measuring pressure and a rotating spindle for smooth thread engagement. The set carries an accuracy rating of 0.004 to 0.005 mm and a graduation of 0.01 mm, making it suitable for precision dimensional inspection work. All micrometers are calibrated and ship with NIST traceability certification included. The enamel finish provides corrosion resistance in shop environments. This set is installed and used by machinists, toolmakers, quality-control technicians, and precision trade professionals who require verified metric measurement across multiple ranges.

This set is well suited for production floors, tool rooms, and inspection stations where multiple measurement ranges are needed without swapping instruments. The 6-piece configuration typically covers incremental 25 mm ranges from 0 to 150 mm, allowing a single set to handle a broad variety of workpiece diameters. The ratchet stop thimble ensures each measurement is taken at a controlled, standardized pressure, which is critical for repeatable readings across different operators or shifts.

Compatibility

Designed as a general-purpose metric outside micrometer set for use in precision measurement, quality inspection, and machining applications requiring coverage from 0 to 150 mm.

Installation Notes

Outside micrometers require no mechanical installation. Store in the provided case to protect calibrated surfaces. Clean spindle and anvil faces before each use to prevent measurement error. Recalibrate with a certified gauge block or standard if the instrument is dropped or subjected to impact. Verification against the included NIST-traceable certification standard is recommended before first use and at regular service intervals.
