Vermont Gage 911219700 Class Zz Minus Plug Pin Gage 0.1970 in

Product Description

The VERMONT GAGE 911219700 is a Class ZZ Minus plug pin gage with a 0.1970-inch nominal diameter, manufactured from steel with a black oxide finish. It is used to verify that a machined hole or bore does not fall below the minimum acceptable size in a NoGo inspection pass. The part holds a tolerance of 0.0002 inches, conforming to Class ZZ standards for plain cylindrical pin gages. Each unit ships with a Certificate of Accuracy with NIST traceability, making it suitable for quality-controlled shop floor and metrology lab environments. Licensed machinists, tooling technicians, and quality inspectors are the primary users of this gage.

This pin gage is designed for NoGo inspection applications where confirming the upper limit of a hole tolerance is required. It is also used to set micrometers, verniers, and other measuring devices to a known reference diameter. The 0.1970-inch diameter suits work involving small-bore precision holes in manufactured parts across general machining, aerospace, automotive, and toolroom environments. The 2-inch overall length provides adequate handling clearance for most standard inspection fixtures and handheld use.

Key Features

• Class ZZ Minus tolerance designation for NoGo inspection use
• 0.0002-inch tolerance for precise upper-limit hole verification
• Steel construction with black oxide coating for corrosion resistance and reduced glare
• Includes Certificate of Accuracy with NIST traceability for documented quality compliance
• 2-inch overall length suitable for handheld and fixture-mounted inspection
• Compatible with micrometers, verniers, and other precision measuring devices as a reference standard

Compatibility

Designed for use in NoGo plug gage inspection procedures and as a setting reference for micrometers, verniers, and other precision measuring devices requiring a 0.1970-inch diameter reference standard.

Installation Notes

Pin gages should be handled with clean, dry hands or lint-free gloves to prevent contamination of the gage surface. Before use, verify the gage and workpiece are at the same ambient temperature to avoid thermal expansion errors. Store the gage in a protective case away from abrasive materials. No power source or mechanical installation is required; inspection should follow your facility's applicable dimensional inspection procedures and quality standards.
