Vermont Gage 112313750 Class Zz Plus Plug Gage 13.75mm

Product Description

The VERMONT GAGE 112313750 is a Class ZZ Plus plug gage designed for precision bore and hole inspection in metrology and quality-control applications. Machined from tool steel, this gage measures 13.75 mm in diameter and holds a tolerance of 0.005 mm, making it suitable for go inspection work where tight dimensional verification is required. The contact surface carries a 10 microfinish rating, ensuring consistent, repeatable gauge contact with the workpiece. Each unit ships with a Certificate of Accuracy traceable to NIST, meeting the documentation requirements common in ISO- and AS9100-registered facilities. Manufactured to ASME B89.1 standards.

This plug gage is used wherever precise hole diameter verification is needed, including production floor go inspection routines, setup verification for CNC and conventional machining operations, and calibration checks on micrometers, verniers, and other measuring devices. The 13.75 mm size covers a common range in mechanical, hydraulic, and precision-assembly work. The 2.0-inch overall length fits standard handle holders used in most inspection and machine-shop environments, allowing fast one-hand operation during high-volume checks.

Key Features

• Class ZZ Plus tolerance: 0.005 mm for high-accuracy go inspection
• 10 microfinish contact surface for consistent, repeatable measurement
• Tool steel construction for wear resistance and long service life
• Conforms to ASME B89.1 dimensional gage standards
• Includes Certificate of Accuracy with NIST traceability for documentation compliance
• 2.0-inch overall length fits standard gage handle holders

Compatibility

Designed as an OEM-style go plug gage for use with standard gage handle holders in bore inspection applications. Compatible with micrometers, verniers, and other measuring devices as a reference or calibration standard, as noted in manufacturer application data.

Installation Notes

Plug gages are handled and used by quality technicians and machinists; no permanent installation is required. Before use, clean the gage and workpiece bore with a lint-free cloth to remove chips, oil, or debris that could affect measurement accuracy. Never force a plug gage into an undersized bore, as this can damage both the gage and the part. Store in a protective case away from temperature extremes to maintain calibration integrity.
