Vermont Gage 111205500 Class Zz Minus Plug Gage 0.055 in

Product Description

The VERMONT GAGE 111205500 is a Class ZZ Minus plug pin gage manufactured from steel for precision dimensional inspection work. This pin gage is ground and finished to a 10 microfinish surface and carries a tolerance of 0.0002 inches in the minus direction, making it a NoGo inspection gage used to verify that a hole or bore does not exceed the maximum allowable limit. At 0.0550 inches in diameter and 2 inches in overall length, it is suited for inspecting small-diameter bores and holes on production floors, inspection benches, and in tool rooms. Each unit ships with a Certificate of Accuracy that includes NIST traceability.

This pin gage is used in quality control and dimensional inspection applications where tight tolerance verification is required. It is appropriate for checking small bores in machined components, verifying hole dimensions on precision assemblies, and setting or checking micrometers, verniers, and other measuring devices. The NoGo designation means this gage is used to confirm that a hole is not oversized beyond the specified limit. It is handled by machinists, quality technicians, and tool room personnel working to standard inspection protocols.

Key Features

• Class ZZ Minus tolerance of 0.0002 inches for NoGo inspection use
• 0.0550 inch measurement diameter for small-bore dimensional checks
• Steel construction with 10 microfinish surface for accurate, repeatable contact
• 2 inch overall length for convenient handling during bench and floor inspection
• Includes Certificate of Accuracy with NIST traceability for quality documentation
• Suitable for setting and checking micrometers, verniers, and other measuring instruments

Compatibility

Designed for use as a NoGo pin gage in standard plug gage inspection setups, and for setting or checking micrometers, verniers, and other dimensional measuring devices requiring a 0.0550 inch reference.

Installation Notes

Pin gages are handled by qualified inspection or tool room personnel following standard metrology practices. Store gages in a clean, dry environment and handle with lint-free gloves or a clean cloth to prevent corrosion and surface contamination. Do not force the gage into a bore; a NoGo gage that enters a hole indicates the hole is out of tolerance. Clean gaging surfaces before and after use per your facility inspection procedure.
