Vermont Gage 112201680 Class Zz Minus Plug Pin Gage 1.68mm

Product Description

The VERMONT GAGE 112201680 is a Class ZZ Minus plug pin gage used to verify bore and hole diameters in precision inspection applications. The gage measures 1.68 mm in diameter with a tolerance of 0.00508 mm, making it suitable for NoGo inspection work where tight dimensional control is required. Machined from steel with a 10 microfinish surface coating, it delivers consistent, repeatable results. Each unit ships with a Certificate of Accuracy traceable to NIST standards. Overall length is 2 inches. Dimensional inspectors, machinists, and quality technicians use this type of gage as part of go/nogo inspection routines and for setting and verifying micrometers, verniers, and other measuring devices.

This plug pin gage is designed for use in precision dimensional inspection environments including machine shops, manufacturing floors, and quality control labs. It is suited for checking bores, holes, and other features where a 1.68 mm diameter must be confirmed to NoGo tolerance. It also serves as a reference standard for calibrating and setting micrometers, verniers, and comparable measuring instruments. Single-unit packaging makes it practical for adding to an existing gage set or replacing a worn pin.

Key Features

• 1.68 mm diameter with 0.00508 mm tolerance for precise dimensional verification
• Steel construction with 10 microfinish surface coating for durability and measurement consistency
• Certificate of Accuracy included with NIST traceability for documentation and audit compliance
• 2-inch overall length for ease of handling during inspection tasks

Compatibility

Designed for use in NoGo inspection routines and for setting micrometers, verniers, and other measuring devices requiring a 1.68 mm reference standard.

Installation Notes

Pin gages are handled and used by dimensional inspectors and machinists following standard metrology practices. Keep the gage clean and lightly oiled when not in use to prevent corrosion on the steel surface. Do not force the pin into a bore; apply only light, controlled hand pressure to avoid damage to the gage or the workpiece. Store in the original case or a protected holder to maintain surface finish and calibration integrity.
