Vermont Gage 111337550 Class Zz Plus Plug Gage 0.3755 in

Product Description

The VERMONT GAGE 111337550 is a Class ZZ Plus plug gage designed to verify bore and hole diameters with precision in industrial and shop-floor inspection environments. The gage measures a nominal diameter of 0.3755 inches with a tolerance of 0.0002 inches, making it suitable for Go inspection work where accurate dimensional verification is required. Manufactured from tool steel and finished to a 10 microfinish surface quality, this plug gage delivers consistent, repeatable results. Each unit ships with a Certificate of Accuracy with NIST traceability, confirming conformance to established metrology standards. Licensed calibration technicians and quality control inspectors are the typical users of this instrument.

This plug gage is used in dimensional inspection applications where verifying hole or bore diameters to close tolerances is critical. It is appropriate for Go inspection routines on production lines, in quality labs, and in toolroom environments. It is also suited for setting and verifying micrometers, verniers, and other measuring devices where a reliable reference standard is needed. The 2.0-inch overall length provides a comfortable handling profile for bench and in-process inspection tasks across a range of manufacturing settings.

Key Features

• 0.0002 inch tolerance classification meeting Class ZZ Plus requirements
• 10 microfinish surface finish for smooth, repeatable gaging contact
• Tool steel construction for hardness and wear resistance
• Includes Certificate of Accuracy with NIST traceability
• Conforms to ASME B89.1 dimensional gage standards

Compatibility

Designed for Go inspection use and as a reference standard for setting micrometers, verniers, and other precision measuring devices in toolroom and quality control applications.

Installation Notes

Plug gages are handled and used by metrology technicians and quality control personnel, not installed in mechanical systems. Store the gage in its protective case when not in use to prevent damage to the precision-finished surface. Clean the gage and the bore being measured before use to eliminate debris that can affect readings. Avoid dropping or impact contact, as this can alter the gage geometry and invalidate its calibration.
