Vermont Gage 111270200 Class Zz Minus Plug Pin Gage

Product Description

The VERMONT GAGE 111270200 is a Class ZZ Minus plug pin gage designed to perform NoGo inspection checks on bored, drilled, or reamed holes to the 0.7020 inch diameter standard. Built from steel with a 10 micro finish, this pin gage delivers the dimensional consistency required for precision tolerance verification on the shop floor or inspection bench. Each unit ships with a Certificate of Accuracy traceable to NIST, supporting documentation requirements in quality-controlled environments. Machinists, quality technicians, and metrology professionals use this gage type to confirm that a feature does not exceed its maximum material condition.

This pin gage is suited for use in both production and inspection settings where hole diameter conformance must be verified against tight tolerances. The minus designation places the gage tolerance in the minus direction from nominal, making it appropriate for NoGo applications. It is also used as a reference tool when setting micrometers, verniers, and other measuring devices to a known diameter. Overall length is 2 inches, giving the gage adequate reach for standard blind and through-hole inspection tasks in general manufacturing and precision machining operations.

Key Features

• Class ZZ Minus tolerance class for NoGo hole inspection
• 0.7020 inch nominal measurement diameter
• Tolerance of 0.0002 inch for precise dimensional verification
• Steel construction with 10 micro surface finish
• Includes Certificate of Accuracy with NIST traceability
• Compatible as a reference standard for setting micrometers, verniers, and other measuring devices

Compatibility

Designed for NoGo inspection of features at 0.7020 inch diameter and for setting micrometers, verniers, and other measuring devices requiring a traceable reference standard at this diameter.

Installation Notes

Pin gages are handled and stored by metrology technicians and quality inspectors following standard gage care procedures. Keep the gage clean and lightly oiled when not in use to prevent corrosion of the steel surface. Handle with clean cotton gloves to avoid thermal expansion from hand contact affecting measurement accuracy. Store in a protective case away from abrasive tools and surfaces to preserve the finish and dimensional integrity.
