Vermont Gage 112212700 Class Zz Minus Plug Pin Gage 12.70mm

Product Description

The VERMONT GAGE 112212700 is a Class ZZ Minus plug pin gage machined from steel for dimensional inspection of bores and holes at 12.70 mm diameter. It carries a tolerance of 0.00508 mm, making it suitable for NoGo inspection applications where confirming an upper limit of bore size is required. The gage measures 2 inches in overall length and ships with a Certificate of Accuracy traceable to NIST standards. Machinists, quality technicians, and metrology professionals use this type of plug gage for incoming inspection, in-process checks, and calibration verification of micrometers, verniers, and other measuring devices.

This pin gage is applied in precision measurement environments including machine shops, manufacturing facilities, and quality control labs. It is suited for checking hole and bore diameters on machined components where a NoGo condition must be confirmed. The 10 microfinish surface coating supports consistent, repeatable gage-to-workpiece contact. It is commonly used alongside ring gages, comparators, and bench micrometers as part of a complete go/nogo inspection process for tolerance verification on production and prototype parts.

Key Features

• Class ZZ Minus tolerance class at 0.00508 mm for NoGo inspection
• 12.70 mm measurement diameter in steel construction
• 10 microfinish surface coating for consistent contact and wear resistance
• Overall length of 2 inches for standard plug gage handling
• Includes Certificate of Accuracy with NIST traceability
• Suitable for use with micrometers, verniers, and other measuring devices

Compatibility

Designed for use in NoGo bore and hole inspection setups and as a calibration reference for set micrometers, verniers, and comparable precision measuring instruments.

Installation Notes

Plug pin gages are handled and used by quality technicians and machinists following standard metrology practices. Store the gage in its protective case when not in use to prevent surface damage and corrosion. Clean the gage and the workpiece bore before each measurement to avoid false readings from debris or oil contamination. Do not force the gage into a bore; light hand pressure is sufficient for a valid NoGo check.
