Vermont Gage 112417310 Class Zz Minus Plug Pin Gage 17.31mm

Product Description

The VERMONT GAGE 112417310 is a Class ZZ minus plug pin gage machined to a 17.31 mm diameter with a tolerance of 0.00508 mm. It is designed for NoGo inspection work, confirming that a bored or reamed hole has not exceeded its maximum allowable size. The steel construction provides the hardness and stability required for repeatable dimensional inspection. Each gage ships with a Certificate of Accuracy traceable to NIST, supporting documentation requirements in calibrated shop and lab environments. Metrology technicians, toolroom machinists, and quality control inspectors are the primary users of this type of gage.

This plug pin gage is used in dimensional inspection of precision holes in manufacturing, toolroom, and quality assurance settings. It is suited for both production-floor go/no-go checks and bench-level measurement verification with micrometers, verniers, and other measuring devices. The minus classification means the gage is ground to the lower boundary of the tolerance band, making it appropriate for NoGo member applications where the gage must not enter a correctly sized hole. It is applicable in both light industrial and high-precision manufacturing environments.

Key Features

• Class ZZ minus tolerance ground to 0.00508 mm for NoGo inspection use
• 17.31 mm nominal diameter for precise hole size verification
• Steel construction for hardness, wear resistance, and dimensional stability
• Overall length of 2 inches for standard handle or direct hand-use applications
• Includes Certificate of Accuracy with NIST traceability for calibration recordkeeping
• 10 micro coating finish to protect against corrosion and handling wear

Compatibility

Designed for use as a NoGo inspection gage and as a setting standard for micrometers, verniers, and other dimensional measuring devices requiring a 17.31 mm reference.

Installation Notes

Plug pin gages are handled and used by metrology technicians and toolroom inspectors rather than installed in a system. Keep the gage clean and lightly oiled when not in use to prevent corrosion. Do not force the gage into a hole; a correctly sized NoGo gage should not enter the hole being inspected. Store in a protective case away from temperature extremes to maintain dimensional accuracy.
