Spi CMS160622049 Outside Micrometer Set 3 Piece

Product Description

The SPI CMS160622049 is a 3-piece mechanical outside micrometer set designed for precision linear measurement in metalworking, machining, and quality-control applications. The set covers a measurement range of 0 to 75 mm with a graduation of 0.01 mm and an accuracy of 0.004 to 0.005 mm, making it suitable for close-tolerance inspection work. Each micrometer features a ratchet stop thimble for consistent measuring force and a rotating spindle. The set arrives NIST-traceable calibrated, supporting documented quality processes. Machinists, tool-and-die technicians, and metrology professionals are the typical end users.

This set is appropriate for use in machine shops, manufacturing facilities, and inspection departments where outside diameter, thickness, and width measurements must be verified to tight tolerances. The three-micrometer configuration spans three distinct measurement ranges within the 0 to 75 mm total span, allowing a single set to cover small-part work through medium-range workpiece dimensions. The enamel finish provides surface protection in a shop environment. No digital counter is included, keeping operation straightforward and battery-free.

Key Features

• 3-piece set covering 0 to 75 mm total measurement range
• 0.01 mm graduation with 0.004 to 0.005 mm accuracy
• Ratchet stop thimble ensures repeatable, consistent measuring force
• Rotating spindle for smooth, controlled advancement
• NIST-traceable calibration certificate included
• Enamel finish for durability in shop environments

Compatibility

Designed as a general-purpose outside micrometer set for use with any workpiece or fixture requiring outside linear measurement in the 0 to 75 mm range. No system-specific or model-specific compatibility restrictions apply.

Installation Notes

Outside micrometers require no installation but should be handled and stored with care to preserve calibration. Before use, verify the zero setting on each micrometer against its reference standard and clean the measuring faces with a lint-free cloth. Do not overtighten the thimble; use the ratchet stop to apply consistent force on every measurement. Store each micrometer in its protective case when not in use to prevent thermal distortion and surface damage.
