Value Collection 616-81606 Class Zz Plug Gage Set 84 Pc

Product Description

The VALUE COLLECTION 616-81606 is an 84-piece Class ZZ plug gage set covering a diameter range of 0.833 to 0.916 inches. Plug gages are precision measurement tools used to verify the inside diameter of bored, drilled, or reamed holes to confirm they fall within acceptable tolerance. This set carries a plus tolerance of 0.0002 inches (0.0002 mm), which is standard for Class ZZ gages — the most common tolerance class for general-purpose GO/NO-GO inspection work in production and maintenance environments. Machinists, tool-and-die workers, and quality control technicians use sets like this for incoming inspection, in-process checks, and final part verification.

This plug gage set is suited for shop-floor and inspection-room use wherever hole diameter verification is required across the 0.833- to 0.916-inch range. The 84-piece count provides full coverage of that range in fine increments, reducing the need to interpolate between sizes. Typical applications include verifying bored housing fits, checking reamed shaft-bore clearances, and qualifying machined components before assembly. The set is appropriate for use in manufacturing, maintenance, repair, and overhaul (MRO) operations across metalworking, HVAC equipment fabrication, and general industrial trades.

Key Features

• Plus tolerance of 0.0002 inches (0.0002 mm) for consistent, repeatable measurement
• Full-range coverage minimizes interpolation between gage sizes
• Suited for production inspection, incoming quality control, and MRO verification tasks

Compatibility

Designed as a general-purpose Class ZZ plug gage set for verifying inside diameters in the 0.833- to 0.916-inch range on machined components across a wide range of industrial and trade applications.

Installation Notes

Plug gages should be handled by qualified machinists or quality technicians following established metrology procedures. Store gages in their protective case when not in use to prevent damage to precision surfaces. Clean both the gage and the workpiece bore before measurement to eliminate debris that could affect readings. Calibrate or verify gages against certified reference standards on a regular schedule to maintain measurement integrity.
