Value Collection 616-81016 Class Zz Plug Gage Set 50 Pc

Product Description

The VALUE COLLECTION 616-81016 is a 50-piece Class ZZ plug gage set designed for checking small-diameter holes and bores in production and inspection environments. The set covers a measurement range of 0.011 to 0.060 inches with a minus tolerance of 0.0002 inches (0.0051 mm), conforming to Class ZZ specifications. Class ZZ gages are the most common GO/NO-GO standard for general-purpose inspection of clearance-fit holes. Machinists, toolroom technicians, and quality control inspectors use this type of set to verify drilled, reamed, or punched hole diameters quickly and accurately on the shop floor or inspection bench.

This set is suited for inspection tasks in machining, fabrication, and manufacturing facilities where small-bore dimensional verification is required. The 50-piece configuration provides continuous coverage across the 0.011 to 0.060 inch range, making it practical for shops working with a wide variety of drill sizes, pin fits, and precision hole requirements. It is appropriate for both production-line go/no-go verification and incoming material inspection.

Key Features

• 50-piece set covers 0.011 to 0.060 inch diameter range in graduated steps
• Class ZZ tolerance of 0.0002 inches (minus tolerance type) for general-purpose inspection
• Designed for GO/NO-GO hole verification in production and quality control environments
• Compact incremental range steps allow coverage of common drill and reamed hole sizes
• Weighs 1.3 pounds — lightweight enough for bench or portable inspection use

Compatibility

Designed as a general-purpose Class ZZ plug gage set suitable for inspecting small-diameter holes across standard machining, fabrication, and light manufacturing applications where minus-tolerance go/no-go verification is required.

Installation Notes

Plug gages are installed and used by machinists, toolroom technicians, and quality control inspectors — no special licensing is required, but proper gage handling practice applies. Always clean and dry the gage and the hole before use to prevent false readings or gage wear. Store gages in the supplied case or a protected organizer to prevent nicks and corrosion. Never force a plug gage into a hole; if the gage does not enter freely during a GO check, the hole is undersized.
