Vermont Gage 112203560 Class Zz Minus Plug Pin Gage 3.56mm

Product Description

The VERMONT GAGE 112203560 is a Class ZZ Minus plug pin gage designed for precision dimensional inspection in industrial and metrology applications. Manufactured from steel with a 10 microfinish surface coating, this pin gage measures a nominal diameter of 3.56 mm with a tolerance of 0.00508 mm. At 2 inches in overall length and weighing just 0.01 pounds, it is sized for handheld use in a gauge stand or direct manual inspection. Each unit ships with a Certificate of Accuracy traceable to NIST, making it suitable for use in quality-controlled environments. Metrology technicians, machinists, and quality inspectors install and use this tool in production and inspection workflows.

This pin gage is intended for NoGo inspection applications, including setting micrometers, verifying vernier calipers, and calibrating other measuring devices that require a known reference diameter. The minus classification means the gage is ground to the lower boundary of the tolerance band, which is the correct designation for a NoGo member in go/no-go inspection pairs. It is well suited for light manufacturing, tool rooms, and quality assurance labs working with small-diameter bores and holes near 3.56 mm.

Key Features

• Class ZZ Minus designation for NoGo inspection use
• 3.56 mm nominal diameter with 0.00508 mm tolerance
• Steel construction with 10 microfinish surface coating for accurate seating
• 2 inches overall length for comfortable handheld or fixture use
• Includes Certificate of Accuracy with NIST traceability

Compatibility

Designed for use in go/no-go inspection setups and as a reference standard for setting micrometers, verniers, and other measuring devices requiring a 3.56 mm diameter reference.

Installation Notes

Pin gages should be handled with clean, dry hands or lint-free gloves to prevent corrosion from skin contact. Store in the provided case or a clean, dry location when not in use. When using to set a measuring instrument, ensure both the pin gage and the instrument are at the same ambient temperature to minimize thermal expansion error. Inspection and calibration work involving NIST-traceable standards should follow the facility quality management procedures.
