Vermont Gage 112208520 Class Zz Minus Plug Pin Gage 8.52 Mm

Product Description

The VERMONT GAGE 112208520 is a Class ZZ Minus plug pin gage with an 8.52 mm measurement diameter, designed for precision dimensional inspection in manufacturing and quality control environments. Built from steel with a 10 microfinish surface coating, this gage delivers a tolerance of 0.00508 mm and comes with a Certificate of Accuracy traceable to NIST standards. At 2 inches overall length and 0.05 pounds, it is compact enough for bench or floor use. Machinists, quality technicians, and tool-and-die professionals rely on this type of gage to verify that a bore or hole does not exceed its maximum allowable size.

This plug pin gage is used in NoGo inspection applications, confirming that a bore or feature falls within tolerance by rejecting oversized conditions. It is also suitable for setting micrometers, verniers, and other precision measuring devices to a known reference diameter. Typical environments include production floor inspection, incoming inspection, and calibration labs. The NIST-traceable certificate supports use in ISO 9001 and AS9100 quality systems where documented traceability is required.

Key Features

• Class ZZ Minus tolerance class: 0.00508 mm tolerance for reliable NoGo inspection
• 8.52 mm measurement diameter for precise bore and hole verification
• Steel construction with 10 microfinish surface for durability and accurate seating
• NIST-traceable Certificate of Accuracy included for quality system compliance
• Compact 2-inch overall length suits bench, floor, and lab use

Compatibility

Designed as a standard Class ZZ Minus plug pin gage for use in NoGo bore inspection routines and as a reference standard for setting micrometers, verniers, and other measuring devices requiring an 8.52 mm diameter reference.

Installation Notes

Plug pin gages require no installation but should be handled with clean, dry hands or lint-free gloves to avoid corrosion and measurement error. Store in a protective case away from temperature extremes to maintain calibration integrity. Do not force the gage into a bore; resistance indicates the feature is within NoGo tolerance. Periodic recalibration against NIST-traceable standards is recommended per your facility quality plan.
