Value Collection 616-81006 Class Zz Plug Gage Set 50 Pc

Product Description

The VALUE COLLECTION 616-81006 is a 50-piece Class ZZ plug gage set covering a measurement range of 0.011 to 0.06 inches. Class ZZ is the most commonly used tolerance grade for general-purpose go/no-go inspection of drilled, reamed, or punched holes in production environments. Each gage in the set carries a plus tolerance of 0.0002 inches (0.0002 mm), providing consistent and reliable dimensional verification. This set is used by machinists, quality control technicians, and tool room personnel who need to confirm whether a hole or bore falls within a specified tolerance without the use of electronic measurement equipment.

This plug gage set is suited for incoming inspection, in-process quality checks, and final part verification across light manufacturing, machine shops, and fabrication facilities. The broad range of 50 gages spanning 0.011 to 0.06 inches makes this set practical for inspecting small-diameter holes produced by drilling, punching, or wire EDM operations. It is a standard reference tool in both job shop and production floor environments where tight dimensional control is required on small-bore features.

Key Features

• 50-piece set covers 0.011 to 0.06 inches in small-diameter increments
• Class ZZ tolerance grade for general-purpose go/no-go hole inspection
• Plus tolerance of 0.0002 inches per gage for consistent dimensional reference
• Suitable for checking drilled, reamed, punched, or EDM-produced holes
• Compact set supports a wide range of small-bore inspection tasks from a single kit

Compatibility

Designed for general-purpose dimensional inspection of small-diameter holes and bores where Class ZZ plug gages are specified as the measurement standard.

Installation Notes

Plug gages are handled and stored by quality control technicians and machinists rather than installed in a system. Store gages in the provided case away from moisture and contaminants to prevent corrosion and dimensional drift. Clean contact surfaces before each use and avoid dropping or striking the gages, as impact can alter their calibrated dimensions. Periodic recalibration against a traceable standard is recommended to maintain measurement integrity over time.
