Vermont Gage 112208460 Class Zz Minus Plug Pin Gage 8.46mm

Product Description

The VERMONT GAGE 112208460 is a Class ZZ Minus plug pin gage machined from steel and used to verify that a bored or reamed hole does not exceed its maximum allowable size. At 8.46 mm in diameter with a tolerance of 0.00508 mm, this gage is sized for NoGo inspection work where tight dimensional control is required. The 10-microfinish surface coating reduces wear and helps maintain accuracy over repeated use cycles. Each unit ships with a Certificate of Accuracy traceable to NIST, supporting quality documentation requirements in regulated manufacturing and metrology environments. Overall length is 2 inches.

This plug pin gage is used in machining, toolroom, and quality-control applications where hole diameter must be confirmed before assembly. It is suited for use alongside set micrometers, verniers, and other precision measuring devices. Typical users include machinists, metrology technicians, and quality inspectors working in manufacturing facilities that require documented dimensional verification. The NoGo designation means this gage is intended to confirm that an oversized condition does not exist, making it one half of a complete Go/NoGo inspection pair.

Key Features

• Class ZZ Minus tolerance classification at 0.00508 mm for precision NoGo inspection
• 8.46 mm measurement diameter in steel construction
• 10-microfinish surface coating for extended wear life and dimensional stability
• Includes Certificate of Accuracy with NIST traceability for quality documentation
• 2-inch overall length for comfortable handling in standard inspection fixtures

Compatibility

Designed for use in NoGo hole inspection applications and compatible with set micrometers, verniers, and other precision measuring devices where an 8.46 mm diameter reference is required.

Installation Notes

Plug pin gages are handled and used by metrology technicians and quality inspectors - not installed in the traditional sense, but proper handling practice still applies. Never force the gage into a bore; light, consistent insertion pressure is correct procedure. Store the gage in its protective case when not in use to prevent nicks or corrosion that would affect accuracy. Periodic recalibration against a NIST-traceable standard is recommended to maintain measurement integrity.
