Vermont Gage 112116380 Class Zz Plus Plug Gage 16.38mm

Product Description

The VERMONT GAGE 112116380 is a Class ZZ Plus plug gage machined from tool steel for dimensional inspection of bored, reamed, and drilled holes. It measures 16.38 mm in diameter with a tolerance of 0.00508 mm and features a 10 microinch finish on the gaging surface. The overall length is 2.0000 inches. Each unit ships with a Certificate of Accuracy traceable to NIST, confirming it meets ASME B89.1 standards. Machinists, quality technicians, and toolroom inspectors use this gage to verify that hole diameters fall within acceptable go-inspection limits before parts move to assembly.

This plug gage is suited for go inspection applications in production and toolroom environments. It is also used to calibrate and verify the accuracy of micrometers, verniers, and other precision measuring devices. The 16.38 mm diameter makes it appropriate for metric-dimensioned workpieces common in automotive, aerospace, and general manufacturing settings. Its Class ZZ Plus tolerance class is designed for inspection-grade work where tighter tolerances than standard Class ZZ are required.

Compatibility

Designed as an OEM-style inspection gage member for use with standard plug gage handles accepting 16.38 mm diameter members. Also suitable for setting and verifying micrometers, verniers, and other precision measuring instruments.

Installation Notes

Plug gage members are installed and used by quality technicians and toolroom machinists following ASME B89.1 inspection procedures. Clean the gage and workpiece bore thoroughly before use to prevent contamination from affecting measurement results. Never force a plug gage into a hole; apply only light hand pressure to avoid damage to the gage surface or the workpiece. Store the gage in its case and apply a light coat of instrument oil when not in use to prevent corrosion.
