Value Collection 616-81616 Class Zz Plug Gage Set 84 Pc

Product Description

The VALUE COLLECTION 616-81616 is an 84-piece Class ZZ plug gage set covering a measurement range of 0.833 to 0.916 inches. Class ZZ plug gages are working-grade instruments used to verify whether a hole or bore falls within an acceptable dimensional tolerance. Each gage in this set holds a minus-tolerance of 0.0002 inches, making the set appropriate for production inspection of machined bores, drilled holes, and reamed passages where dimensional accuracy matters. Machinists, tool-and-die technicians, and quality-control inspectors rely on plug gage sets like this one to quickly go/no-go check inside diameters without requiring measurement instruments such as bore gauges or CMMs.

This set is suited for use in machine shops, manufacturing facilities, and fabrication environments where repetitive bore inspection is part of the production workflow. The 84-piece configuration provides broad coverage across the 0.833 to 0.916 inch range, allowing technicians to address a wide variety of hole sizes within a single kit. Class ZZ designation indicates a working-grade tolerance class, commonly used for incoming inspection, in-process checks, and quality-assurance routines on standard-tolerance machined parts.

Key Features

• 84-piece set covering 0.833 to 0.916 inches range for broad bore inspection coverage
• Class ZZ working-grade tolerance classification suitable for production inspection
• Minus-tolerance type at 0.0002 inches per gage for consistent dimensional verification
• Go/no-go inspection method reduces reliance on measuring instruments during production
• Set weight of 35 pounds provides robust, shop-grade construction across all pieces

Compatibility

Designed as a working-grade plug gage set for standard production inspection of inside diameters in the 0.833 to 0.916 inch range across machined components and assemblies.

Installation Notes

Plug gages should be handled and stored according to standard metrology practices to preserve accuracy. Clean bores and gage surfaces before use to prevent contamination from affecting readings. Gages should be stored in their protective case when not in use and periodically calibrated against master setting rings to verify continued accuracy. Consult applicable ASME B89 or equivalent standards for gage care, handling, and recalibration intervals.
