Value Collection 616-81516 Class Zz Plug Gage Set 82 Pc

Product Description

The VALUE COLLECTION 616-81516 is an 82-piece Class ZZ plug gage set covering a diameter range of 0.751 to 0.832 inches. Each plug gage in the set is manufactured to a minus-tolerance of 0.0002 inches, conforming to Class ZZ standards for go/no-go inspection of through-holes and bores. This type of set is used in dimensional quality control and incoming inspection work, where confirming a bore is within tolerance is faster and more reliable than using a measuring instrument alone. Machinists, toolmakers, and quality technicians are the primary users.

This set is suited to production and inspection environments where holes in the 0.751 to 0.832 inch diameter range are routinely checked. The 82-piece count provides incremental coverage across that range, allowing techs to verify tight-tolerance bores on machined parts, castings, and fabricated components. The set is appropriate for both job-shop and high-volume manufacturing inspection stations where Class ZZ accuracy is the specified requirement.

Compatibility

Designed as a standard Class ZZ plug gage set for inspecting bored, drilled, or reamed holes in the 0.751 to 0.832 inch diameter range across a wide range of machined and fabricated parts.

Installation Notes

Plug gages are handled and used by quality technicians and machinists following standard metrology practices. Before use, clean and deburr the bore being inspected to prevent gage wear or false readings. Handle gages with clean, dry hands or lint-free gloves to prevent corrosion from skin contact. Store the set in its case when not in use to protect gage surfaces and maintain calibration integrity.
