Vermont Gage 112115180 Class Zz Plus Plug Gage 15.18mm

Product Description

The VERMONT GAGE 112115180 is a Class ZZ Plus plug gage machined from tool steel and finished to a 10 micro surface coating. It measures 15.18 mm in diameter with a tolerance of 0.00508 mm, making it suitable for precision bore inspection in manufacturing and metrology environments. The overall length is 2.0000 inches. Each unit ships with a Certificate of Accuracy traceable to NIST, confirming it meets ASME B89.1 dimensional standards. Machinists, quality technicians, and metrology professionals use this type of gage to verify hole size during incoming inspection, in-process checks, and final part acceptance.

This plug gage is designed for go inspection applications where tight dimensional control is required. It is compatible with workflows involving micrometers, verniers, and other precision measuring devices as a calibration or reference standard. Typical use environments include machine shops, production floors, and quality labs handling turned, bored, or reamed components where 15.18 mm hole tolerances must be confirmed to ASME B89.1 requirements.

Key Features

• Tool steel construction for wear resistance and dimensional stability
• 10 micro surface finish coating for consistent gage contact
• Includes Certificate of Accuracy with NIST traceability
• Conforms to ASME B89.1 standards
• Compatible with micrometers, verniers, and other precision measuring devices

Compatibility

Designed for use as a go inspection plug gage with micrometers, verniers, and other precision measuring devices requiring a 15.18 mm diameter reference standard.

Installation Notes

Plug gages are handled and used by quality technicians and machinists in inspection settings. Store the gage in its protective case when not in use to prevent surface damage and corrosion. Clean the gage surface before each use with an appropriate solvent to remove oils and debris that could affect measurement accuracy. Avoid dropping or striking the gage, as impact damage will compromise dimensional integrity and void traceability.
