Vermont Gage 111115700 Class Zz Plus Plug Gage 0.157 in

Product Description

The VERMONT GAGE 111115700 is a Class ZZ Plus plug gage designed for precise go inspection of bored, drilled, or reamed holes. It measures a nominal diameter of 0.157 inches with a tolerance of 0.0002 inches, making it suitable for high-accuracy dimensional verification. The gage is machined from tool steel and features a 10 microfinish surface on the measuring member. Each unit ships with a Certificate of Accuracy traceable to NIST, supporting quality documentation requirements. This tool is used by machinists, quality control technicians, and tool-room personnel who need reliable, repeatable measurement in production and inspection environments.

This plug gage is built for go inspection tasks in manufacturing and metrology settings. It is commonly used alongside set micrometers, verniers, and other precision measuring devices to verify hole diameters in machined parts. Typical applications include checking tolerance compliance on production components in job shops, general manufacturing facilities, and quality labs. The 2.0-inch overall length provides a standard handling profile for single-end plug gage use. Conformance to ASME B89.1 ensures the gage meets recognized dimensional metrology standards.

Installation Notes

Plug gages are installed and used by quality control technicians and machinists in inspection and tool-room environments. Handle measuring surfaces with care and avoid dropping or striking the gage member against hard surfaces, as this can affect calibration. Clean the gage and the part being inspected before use to remove chips, coolant, and debris. Store the gage in its protective case when not in use to prevent corrosion and surface damage to the tool steel.
