Vermont Gage 111425150 Class Zz Minus Plug Pin Gage 0.2515 in

Product Description

The VERMONT GAGE 111425150 is a Class ZZ minus plug pin gage used to perform NoGo inspection on precision bored or reamed holes. It provides a fast, reliable go/no-go reference for machinists, quality control technicians, and metrologists verifying hole diameter tolerances on the shop floor or in an inspection lab. The gage measures 0.2515 inches in diameter with a tolerance of 0.0002 inches, and it comes with a Certificate of Accuracy traceable to NIST. The steel construction and 10 microfinish surface deliver consistent contact and long service life under routine inspection use.

This pin gage is suited for use in manufacturing and machining environments where hole diameter verification is required on production parts. It is commonly used alongside set micrometers, verniers, and other precision measuring devices to confirm that bored, drilled, or reamed holes fall within a specified minus tolerance. The 2-inch overall length keeps it easy to handle for single-handed checks on parts held in a vise or fixture. It is appropriate for both high-volume production inspection and low-volume tool room applications.

Key Features

• Class ZZ minus tolerance for NoGo inspection applications
• 0.2515 inch measurement diameter with 0.0002 inch tolerance
• NIST-traceable Certificate of Accuracy included
• 10 microfinish surface for repeatable, low-wear contact
• Steel construction for durability in production environments
• 2 inch overall length for easy single-handed use

Compatibility

Designed for use as a NoGo plug gage in standard pin gage sets and inspection routines involving set micrometers, verniers, and other precision measuring devices requiring a 0.2515 inch diameter reference.

Installation Notes

Pin gages are handled and used by quality control technicians and machinists — no installation in the traditional sense is required. Keep the gage clean and lightly oiled when stored to prevent corrosion on the steel surface. Do not force the pin into a hole; proper NoGo inspection relies on the pin not entering the feature under hand pressure alone. Store the gage in its case away from other metal tools to avoid nicks or surface damage that would affect measurement accuracy.
