Vermont Gage 112413790 Class Zz Minus Plug Pin Gage

Product Description

The VERMONT GAGE 112413790 is a Class ZZ Minus plug pin gage designed for NoGo inspection applications in precision measurement environments. Machined from steel with a diameter of 13.79 mm and an overall length of 2 inches, this pin gage holds a tolerance of 0.00508 mm, making it suitable for verifying that a bore or hole does not exceed its maximum allowable size. It is a single-ended pin gage used in quality control, metrology labs, and on the shop floor. Each unit ships with a Certificate of Accuracy that carries NIST traceability, confirming the gage has been verified against a national standard.

This pin gage is used wherever dimensional verification of holes, bores, or slots is required. Typical applications include NoGo inspection checks on machined parts, setting and verifying micrometers, verniers, and other measuring devices, and general dimensional quality assurance in manufacturing environments. It is appropriate for both production floor use and toolroom metrology. The 13.79 mm diameter targets metric-dimensioned workpieces in aerospace, automotive, and general precision machining applications.

Key Features

• Class ZZ Minus tolerance class: 0.00508 mm tolerance for NoGo inspection use
• Steel construction with a 10 Micro coating and finish for wear resistance and surface integrity
• NIST-traceable Certificate of Accuracy included with each gage
• 2 inch overall length provides a stable grip for hand use or fixture mounting
• Single-piece design suited for micrometers, verniers, and other measuring device calibration

Compatibility

Designed for use as a NoGo inspection gage and for setting micrometers, verniers, and other measuring devices requiring a 13.79 mm reference standard.

Installation Notes

Pin gages are handled and used by quality technicians, machinists, and metrologists. Always clean the gage and the workpiece bore before use to prevent measurement error caused by debris or oil film. Store the gage in its protective case when not in use to avoid nicks or corrosion that would compromise the tolerance class. Do not force the gage into a bore; if resistance is felt, the hole is at or below the NoGo limit.
