Vermont Gage 101400400 Class Zz Plug Gage Set 190 Pc

Product Description

The VERMONT GAGE 101400400 is a 190-piece Class ZZ plug gage set designed for precise hole diameter measurement and dimensional inspection work. The set covers a range of 0.0615 to 0.2505 inches with a minus tolerance of 0.000200 inches, meeting Class ZZ standards for general-purpose inspection gaging. Each gage is manufactured from steel and comes with a Certificate of Accuracy backed by NIST traceability. Machinists, quality control technicians, and toolroom professionals use sets like this for go/no-go inspection, incoming and in-process quality checks, and calibration of other measuring instruments.

This plug gage set is suited for shop-floor and inspection-room use in both production and job-shop environments. Typical applications include measuring hole diameters, calculating distances between holes, gaging slot widths and locations, performing NO-GO gaging inspection, and setting micrometers, verniers, and other precision measuring devices. The 190-piece range provides broad coverage for standard inch-dimension work across a wide variety of workpiece features commonly encountered in machining and fabrication.

Compatibility

Designed as a general-purpose Class ZZ plug gage set for standard inch-dimension inspection applications in machining, fabrication, and quality control settings.

Installation Notes

Plug gages are handled and used by quality technicians, machinists, and toolroom personnel rather than installed in a system. Store gages in the provided case and keep them clean and lightly oiled to prevent corrosion. Never force a plug gage into a hole; apply only light hand pressure to avoid damaging the gage or the workpiece. Follow your facility calibration schedule and refer to the included NIST traceable Certificate of Accuracy for traceability documentation.
