Vermont Gage 111286600 Class Zz Minus Plug Pin Gage 0.8660 in

Product Description

The VERMONT GAGE 111286600 is a Class ZZ Minus plug pin gage designed to check hole diameters in NoGo inspection applications. It measures 0.8660 inches in diameter with a tolerance of 0.0002 inches, making it suitable for verifying that a bore or hole does not fall within an out-of-tolerance condition. The overall length is 2 inches. Machined from steel, this pin gage ships with a Certificate of Accuracy that carries NIST traceability, supporting documented quality control requirements. Machinists, quality technicians, and tool-and-die professionals use this gage for reliable, repeatable dimensional verification.

This pin gage is used in manufacturing, machining, and quality assurance environments where precise hole-diameter inspection is required. It is suited for NoGo inspection checks and for setting or verifying micrometers, verniers, and other measuring devices to a known reference diameter. Typical applications include production floor inspection, incoming inspection, and calibration lab use. The 0.8660-inch diameter targets bores machined to that nominal size across a range of industries including aerospace, automotive, and general metalworking.

Key Features

• Class ZZ Minus tolerance class — 0.0002 inches — for NoGo inspection use
• 0.8660-inch measurement diameter, 2-inch overall length
• Steel construction for durability and dimensional stability
• 10 micro finish coating for consistent surface contact
• Includes Certificate of Accuracy with NIST traceability for documented QC compliance

Compatibility

Designed for use in NoGo hole inspection and as a reference standard for setting micrometers, verniers, and other measuring devices requiring a 0.8660-inch diameter reference.

Installation Notes

Pin gages should be handled with clean, dry hands or lint-free gloves to prevent corrosion and contamination of the gage surface. Before use, verify the gage surface is free of burrs, debris, or oil that could affect measurement accuracy. Store the gage in its protective case when not in use to maintain the finish and dimensional integrity. Calibration intervals should follow the facility quality management plan and applicable metrology standards.
