Vermont Gage 112208040 Class Zz Minus Plug Pin Gage 8.04mm

Product Description

The VERMONT GAGE 112208040 is a Class ZZ Minus plug pin gage machined to a 8.04 mm diameter with a tolerance of 0.00508 mm. This single-ended pin gage is used to verify whether a hole or bore falls outside an acceptable dimension, functioning as a NoGo inspection tool. Manufactured from steel with a 10 microfinish surface coating, it provides consistent, repeatable measurement results. Each unit ships with a Certificate of Accuracy traceable to NIST standards, satisfying quality documentation requirements in precision manufacturing and metrology environments. Licensed metrologists, quality technicians, and tool-and-die professionals are the primary users.

This pin gage is suited for NoGo inspection tasks in production and quality control settings. It is also used to set micrometers, verniers, and other measuring devices where a precise reference diameter is required. The 8.04 mm size fits into dimensional verification workflows for machined bores, drilled holes, and precision-fit components across industrial manufacturing, aerospace, and general metalworking applications. At 2 inches overall length, it is easy to handle for single-hand inspection operations.

Key Features

• Class ZZ Minus tolerance classification at 0.00508 mm for NoGo inspection use
• 8.04 mm diameter machined from steel with a 10 microfinish surface coating
• NIST-traceable Certificate of Accuracy included with each unit
• 2-inch overall length for easy single-hand handling
• Compatible with micrometers, verniers, and other precision measuring devices as a reference standard

Compatibility

Designed for use in NoGo bore and hole inspection applications and as a reference setting tool for micrometers, verniers, and other precision measuring devices requiring an 8.04 mm diameter reference.

Installation Notes

Pin gages are handled and deployed by quality technicians and metrologists following established metrology procedures. Clean the gage and the bore or measuring device contact surfaces before use to prevent debris from affecting readings. Store the gage in its case when not in use to protect the precision ground surface. Do not force the gage into a bore - light hand pressure is the correct application method.
