Vermont Gage 112112960 Class Zz Plus Plug Gage 12.96mm

Product Description

The VERMONT GAGE 112112960 is a Class ZZ Plus plug gage designed for dimensional inspection of bored and reamed holes at a 12.96 mm nominal diameter. Built from tool steel with a 10 micro finish, it holds a tolerance of 0.00508 mm, making it suitable for Go inspection applications where consistent, repeatable measurement is required. Each unit ships with a Certificate of Accuracy traceable to NIST, meeting ASME B89.1 standards. Machinists, quality technicians, and metrology professionals use this gage to verify hole diameters against specified tolerances on the shop floor or in an inspection lab.

This plug gage is used in Go inspection routines to confirm that a hole falls within the acceptable minimum material condition. It is compatible with calibration and verification workflows alongside set micrometers, verniers, and other precision measuring devices. At 2.0000 inches overall length and 0.12 pounds, it is compact enough for benchtop inspection or in-process checks on machined components in both job shop and production environments.

Compatibility

Designed for use in Go inspection applications alongside set micrometers, verniers, and other precision measuring devices per ASME B89.1 requirements.

Installation Notes

Plug gages are handled and used by quality technicians and machinists following standard metrology practices. Keep the gage clean and lightly oiled when not in use to prevent corrosion on the tool steel surface. Do not force the gage into a hole; apply only light, consistent hand pressure to avoid damaging the gage or the workpiece. Store in the provided case or a clean, dry environment to maintain calibration integrity.
