Vermont Gage 112403510 Class Zz Minus Plug Pin Gage 3.51mm

Product Description

The VERMONT GAGE 112403510 is a Class ZZ Minus plug pin gage ground to a 3.51 mm diameter with a tolerance of 0.00508 mm. It is used to verify that a hole or bore does not exceed its maximum allowable size, making it a NoGo inspection gage. The steel construction and 10 microfinish surface provide consistent, repeatable contact with the workpiece. Each unit ships with a Certificate of Accuracy traceable to NIST, which is required for documented quality systems and calibration records. Machinists, quality technicians, and toolroom professionals use this gage in production inspection and measuring equipment setup.

This plug pin gage is suited for dimensional inspection in manufacturing environments where bore diameter control is critical. It is compatible with NoGo inspection procedures and can be used alongside set micrometers, verniers, and other precision measuring devices to establish and verify calibration. The 2-inch overall length fits standard pin gage handles and holding fixtures commonly found on the shop floor or in the metrology lab. It is appropriate for both high-volume production inspection and low-volume precision work where NIST-traceable documentation is required.

Key Features

• Class ZZ Minus tolerance ground to 0.00508 mm for NoGo inspection applications
• 3.51 mm diameter with 10 microfinish surface for accurate, repeatable bore contact
• Steel construction for durability in production inspection environments
• 2-inch overall length fits standard pin gage handles and holding fixtures
• Includes Certificate of Accuracy with NIST Traceability for quality system compliance

Compatibility

Designed for use in NoGo bore inspection procedures and as a reference standard for setting micrometers, verniers, and other precision measuring devices.

Installation Notes

Pin gages are handled and used by quality technicians and machinists; no installation in a mechanical system is required. Store the gage in its protective case when not in use to prevent surface damage and corrosion. Clean the gage pin and the bore being measured before use to avoid false readings caused by debris or oil film. Do not force the pin into an undersized bore, as this can damage the gage or alter its calibration.
