Vermont Gage 111245700 Class Zz Minus Plug Gage 0.4570 in

Product Description

The VERMONT GAGE 111245700 is a Class ZZ Minus plug pin gage ground to a 0.4570-inch diameter for NoGo inspection work. It measures 2 inches in overall length and is machined from steel with a 10-microfinish surface coating for consistent, repeatable contact. Each gage ships with a Certificate of Accuracy traceable to NIST, making it suitable for quality-controlled shop environments. This tool is used by machinists, quality technicians, and calibration professionals to verify that a hole or bore does not exceed a specified maximum allowable size.

This plug pin gage is applied in NoGo inspection routines where a hole must be confirmed as within tolerance. It is also compatible with setting and checking micrometers, verniers, and other precision measuring devices. The Class ZZ tolerance designation indicates a general-purpose inspection grade appropriate for standard shop floor and inspection room use. Typical applications include incoming inspection, in-process quality checks, and calibration of measuring instruments in manufacturing and machining environments.

Designed for NoGo inspection of bores and holes at 0.4570-inch diameter, and for setting micrometers, verniers, and other precision measuring devices.

Installation Notes

Plug pin gages are handled and used by machinists, quality technicians, and metrologists — no installation in the traditional sense applies. Keep the gage clean and lightly oiled when stored to prevent corrosion. Do not force the gage into a bore; apply only light, controlled hand pressure to avoid damage to the gage or the workpiece. Verify the gage certificate is current before using it in a calibration or inspection procedure.
