Vermont Gage 112200980 Class Zz Minus Plug Pin Gage 0.98 Mm

Product Description

The VERMONT GAGE 112200980 is a Class ZZ minus plug pin gage with a 0.98 mm diameter, designed for precision dimensional inspection in manufacturing and metrology environments. It carries a tolerance of 0.00508 mm and features a 10 microfinish coating for consistent, repeatable contact. The gage measures 2 inches in overall length and is machined from steel for durability in production or inspection floor conditions. A Certificate of Accuracy with NIST traceability is included, meeting documentation requirements for quality management systems. Licensed metrology technicians, machinists, and quality control inspectors are the typical users of this tool.

This plug pin gage is intended for NoGo inspection applications, where the goal is to confirm that a bore or hole does not exceed the maximum allowable size. It is also used for setting micrometers, verniers, and other measuring devices requiring a known reference diameter. Suitable for both production floor and inspection lab environments, this gage is sized for very fine-tolerance applications where sub-millimeter accuracy is required. Its compact diameter makes it well-suited for inspecting small bores and precision-machined features in industries such as aerospace, automotive, and general machining.

Key Features

• Class ZZ minus tolerance rating for NoGo inspection applications
• 0.00508 mm tolerance for sub-millimeter precision measurement
• 10 microfinish surface coating for consistent, repeatable gage contact
• Steel construction for durability in production and inspection environments
• Includes Certificate of Accuracy with NIST traceability for QMS documentation
• Compact 2-inch overall length suitable for bench and inline inspection use

Compatibility

Designed for use in NoGo inspection setups and for setting micrometers, verniers, and other precision measuring devices requiring a calibrated 0.98 mm reference diameter.

Installation Notes

Plug pin gages should be handled with clean, dry hands or lint-free gloves to prevent contamination of the gage surface and the bore being measured. Store the gage in its protective case when not in use to prevent corrosion and damage to the finish. Apply a light film of instrument-grade oil during storage to maintain the steel surface. Inspection procedures using this gage should follow applicable standards such as ASME B89.1.5 for gage calibration and care.
