Vermont Gage 112206460 Class Zz Minus Plug Pin Gage 6.46 Mm

Product Description

The VERMONT GAGE 112206460 is a Class ZZ Minus plug pin gage with a 6.46 mm measurement diameter, manufactured from steel and finished to a 10 microfinish surface. It is used to verify that a hole or bore does not exceed its maximum acceptable size, making it a NoGo inspection tool. The gage carries a tolerance of 0.00508 mm and comes with a Certificate of Accuracy that includes NIST traceability, confirming it meets the dimensional standards required for quality control work. At 2 inches in overall length and 0.03 pounds, it is a compact, hand-held precision instrument suited for use on the shop floor or in a metrology lab.

This plug pin gage is designed for NoGo inspection applications where confirming maximum material condition is critical. It is also appropriate for setting and verifying micrometers, verniers, and other measuring devices that require a traceable dimensional reference. Typical users include machinists, quality control inspectors, and toolroom technicians working in precision manufacturing environments. The Class ZZ tolerance classification places this gage in the range used for general inspection of commercial and industrial parts rather than master-gage or working-gage applications that demand tighter classifications.

Key Features

• Class ZZ Minus designation - calibrated as a NoGo gage for maximum-limit bore inspection
• 0.00508 mm tolerance for reliable dimensional verification
• 10 microfinish surface coating for smooth, repeatable contact with measured features
• Steel construction for durability in production and inspection environments
• Includes Certificate of Accuracy with NIST traceability
• Compact 2-inch overall length for easy single-hand use

Compatibility

Designed for use in NoGo bore inspection applications and as a setting reference for micrometers, verniers, and other measuring devices requiring a traceable dimensional standard at 6.46 mm.

Installation Notes

Pin gages are handled and used by trained metrology or quality control personnel. Before use, clean the gage and the bore or instrument being checked to prevent measurement errors from debris or oil film. Do not force the gage into a bore - apply light, consistent hand pressure only. Store the gage in its protective case when not in use to preserve the surface finish and dimensional integrity.
