Vermont Gage 111288500 Class Zz Minus Plug Pin Gage 0.8850 in

Product Description

The VERMONT GAGE 111288500 is a Class ZZ Minus plug pin gage designed for precise dimensional inspection in manufacturing and quality control environments. This gage measures bore diameters at 0.8850 inches with a tolerance of 0.0002 inches, providing the accuracy required for NoGo inspection applications. Constructed from steel with a 10 microinch surface finish, it delivers consistent, repeatable results. Each unit ships with a Certificate of Accuracy with NIST Traceability, making it suitable for documented inspection programs. Machinists, quality technicians, and tool room professionals rely on this type of gage for verifying hole sizes against specified limits.

This plug pin gage is used in NoGo inspection applications to confirm that a bore or hole does not exceed its maximum allowable dimension. It is also well suited for setting and verifying micrometers, verniers, and other measuring devices in shop floor and laboratory settings. The 2-inch overall length provides adequate handling clearance for most standard inspection fixtures and bore configurations. Applicable in both production and tool room environments where dimensional tolerance control is critical.

Key Features

• Class ZZ Minus tolerance classification for NoGo inspection use
• Measurement diameter of 0.8850 inches with a 0.0002-inch tolerance
• Steel construction with a 10 microinch surface finish for consistent contact
• Certificate of Accuracy with NIST Traceability included for documented quality programs
• Suitable for setting micrometers, verniers, and other precision measuring instruments
• Overall length of 2 inches for standard handling in typical inspection setups

Compatibility

Designed as an OEM-style Class ZZ Minus plug pin gage for use in NoGo bore inspection applications and for setting micrometers, verniers, and other precision measuring devices where a 0.8850-inch reference diameter is required.

Installation Notes

Pin gages are handled and used by quality technicians and machinists in inspection or tool room settings. Clean the gage and the bore surface before use to prevent debris from affecting measurement accuracy. Store the gage in its protective case when not in use to avoid surface damage that could affect tolerance. Do not force the gage into a bore; proper Class ZZ Minus gaging relies on controlled hand pressure only.
