Vermont Gage 112408710 Class Zz Minus Plug Pin Gage 8.71mm

Product Description

The VERMONT GAGE 112408710 is a Class ZZ minus plug pin gage machined to measure an 8.71 mm diameter with a tolerance of 0.00508 mm. It is used as a NoGo member in go/no-go inspection routines to verify that a bore or hole does not exceed its maximum allowable size. Manufactured from steel with a 10 microfinish surface coating, this pin gage delivers the dimensional stability and surface quality required for reliable attribute gauging. Each unit ships with a Certificate of Accuracy traceable to NIST standards, supporting quality system documentation requirements in ISO and AS9100 environments. Machinists, quality technicians, and metrology professionals are the primary users of this tool.

This pin gage is suited for inspection of machined holes, bores, and precision-fit features on production floors and in inspection labs. It is used alongside set micrometers, verniers, and other measuring devices for go/no-go attribute gauging. The 8.71 mm diameter and minus tolerance classification make it appropriate for NoGo inspection checks where the gage must not enter a correctly sized bore. Overall length is 2 inches, making it compatible with standard pin gage handles and fixtures commonly found in quality control departments serving aerospace, automotive, and general manufacturing applications.

Compatibility

Designed for use as a NoGo plug pin gage with set micrometers, verniers, and other precision measuring devices in standard go/no-go inspection setups.

Installation Notes

Pin gages are handled and used by quality technicians and machinists in inspection environments. Keep the gage clean and lightly oiled when not in use to prevent corrosion on the steel body. Never force a pin gage into a bore; apply only light hand pressure to avoid damage to the gage or the workpiece. Store in a protective case away from abrasive materials and temperature extremes to maintain dimensional accuracy.
