Spi CMS161205007 Outside Micrometer 6 Inch

Product Description

The SPI CMS161205007 is a mechanical outside micrometer designed for precise external dimensional measurement in machining, metrology, and quality control environments. It covers a full 6-inch measurement range with a graduation of 0.0001 inches and a stated accuracy of 0.0002 inches. The measuring faces are solid carbide for long-term wear resistance. A ratchet stop thimble ensures consistent measuring force on every reading, reducing operator-to-operator variation. This tool ships calibrated with NIST traceability certification included, making it suitable for controlled inspection environments and ISO-compliant shop floors. Machinists, tool-and-die technicians, and metrology professionals are the primary users.

The CMS161205007 is suited for precision measurement tasks in manufacturing, maintenance, and inspection applications where tight tolerances must be verified on external features such as shafts, pins, and bearing seats. The 6-inch range makes it applicable to mid-size workpieces common in general machining and fabrication. The included protective case and Short Form Certificate of Calibration with NIST-traceable standards support both shop-floor use and documented inspection workflows.

Key Features

• 6-inch measurement range for mid-size external dimensions
• 0.0001 inch graduation for high-resolution readings
• 0.0002 inch stated accuracy
• Solid carbide measuring faces resist wear over extended service
• Ratchet stop thimble provides repeatable measuring force
• Ships calibrated with NIST traceability certification, case, and Short Form Certificate of Calibration
• Satin chrome finish reduces glare and corrosion

Compatibility

Designed as an OEM-style mechanical outside micrometer for general-purpose external measurement applications across machining, inspection, and quality assurance environments.

Installation Notes

Outside micrometers require no installation but should be handled by calibration technicians or machinists familiar with proper zeroing and anvil-cleaning procedures before use. Store in the included case when not in use to protect the measuring faces and maintain calibration integrity. Verify the zero setting against a reference standard before each measurement session. Do not force the thimble beyond the measurement range, as this can damage the spindle threads.
