Vermont Gage 111406950 Class Zz Minus Plug Pin Gage

Product Description

The VERMONT GAGE 111406950 is a Class ZZ Minus plug pin gage machined from steel for dimensional inspection of small-diameter bores and holes. It measures 0.0695 inches in diameter with a tolerance of 0.0002 inches, making it suitable for NoGo inspection applications where close-tolerance verification is required. The overall length is 2 inches. Each gage ships with a Certificate of Accuracy bearing NIST traceability, confirming it meets Class ZZ Minus standards. Machinists, quality technicians, and tool room personnel use plug pin gages like this one to verify hole sizes quickly and reliably at the inspection bench or on the shop floor.

This pin gage is intended for NoGo inspection use, confirming that a drilled, reamed, or otherwise finished hole does not exceed its maximum material condition limit. It is also suitable for setting micrometers, verniers, and other measuring devices requiring a certified reference standard. Typical applications include precision machining shops, tool and die operations, metrology labs, and any production environment where small-bore hole tolerances must be verified. The 0.0695 inch diameter size serves fine-pitch fastener clearance holes and similar tight-tolerance features.

Key Features

• Class ZZ Minus tolerance of 0.0002 inches for NoGo inspection accuracy
• 0.0695 inch measurement diameter for small-bore verification
• 2 inch overall length for easy handling and measurement access
• Steel construction for durability and dimensional stability
• 10 Microfinish surface coating for consistent gage contact and wear resistance
• Includes Certificate of Accuracy with NIST traceability

Compatibility

Designed for use in NoGo plug gage inspection routines and as a reference standard for setting micrometers, verniers, and other precision measuring devices requiring a certified 0.0695 inch diameter reference.

Installation Notes

Pin gages are installed and used by quality technicians and machinists in inspection environments. Handle with clean, dry hands or lint-free gloves to prevent corrosion from skin oils. Store in a protective case when not in use to preserve the precision-ground surface finish. Do not force the gage into a hole; any resistance indicates the hole is at or below the NoGo limit, which is the intended function of this class of gage.
