Vermont Gage 112101960 Class Zz Plus Plug Gage 1.96mm

Product Description

The VERMONT GAGE 112101960 is a Class ZZ Plus plug gage designed for precision dimensional inspection of small-diameter bores and holes. The gage measures 1.96 mm in diameter with a tolerance of 0.00508 mm, making it suitable for applications where tight dimensional control is required. Manufactured from tool steel with a 10 microfinish surface coating, it delivers the surface quality and durability expected in calibration and inspection environments. Each unit ships with a Certificate of Accuracy traceable to NIST, supporting quality management and documentation requirements. Licensed metrologists, quality technicians, and tool-room professionals are the typical end users.

This plug gage is used in go inspection applications to verify that a bore or hole is within the minimum acceptable size. It is also suitable for setting micrometers, verniers, and other measuring devices that require a certified reference standard. Typical environments include manufacturing inspection stations, tool rooms, metrology labs, and calibration benches where ASME B89.1 compliance is required. The 1.96 mm diameter targets small-bore applications common in precision machining and instrument manufacturing.

Compatibility

Designed as an OEM-style go plug gage for use with standard gage handle holders accepting 1.96 mm diameter wire-type plug gages, and as a reference standard for compatible measuring devices in precision inspection workflows.

Installation Notes

Plug gages are handled and used by quality technicians and metrologists in inspection or calibration settings. 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 bore; use only hand pressure consistent with standard go-gage practice. Store in a protective case away from temperature extremes to maintain dimensional accuracy.
