Spi CMS160412053 Point Micrometer 1 Inch Ratchet Stop

Product Description

The SPI CMS160412053 is a mechanical point micrometer designed for precision measurement in tight or restricted areas where a standard flat anvil cannot reach. Measuring to an accuracy of 0.0001 inch over a 1-inch range, it features a ratchet-stop thimble for consistent measuring force and a 30-degree point angle on both the spindle and anvil. The carbide-tipped spindle and anvil resist wear during repetitive use. A painted frame with integrated heat shield protects against thermal transfer from the operator's hands, preserving measurement integrity. The tool ships with a case and a short-form certificate of calibration.

This micrometer suits machinists, toolmakers, and quality control technicians who need to measure grooves, keyways, gear teeth, and other narrow or tapered features. Its mechanical operation requires no batteries or electronic components, making it reliable in shop-floor environments with coolant mist, vibration, or temperature variation. The included calibration certificate supports quality management systems and documentation requirements.

Key Features

• 0.0001 inch accuracy over a 1-inch measuring range
• 30-degree point angle on both carbide spindle and carbide anvil for access to narrow features
• Ratchet-stop thimble for repeatable, consistent measuring force
• Rotating spindle design
• Painted frame with heat shield to minimize thermal influence
• Includes protective case and short-form certificate of calibration

Compatibility

Designed as an OEM-style precision measuring tool suitable for general metrology and inspection applications requiring a 1-inch range point micrometer.

Installation Notes

Point micrometers are used by machinists and quality technicians and require no permanent installation. Before use, verify the zero setting against the supplied calibration standard or gauge blocks in accordance with your facility calibration procedure. Store in the included case when not in use to protect the carbide contact points from impact and contamination. Avoid applying excess force beyond the ratchet-stop engagement to prevent measurement error or tip damage.
