Value Collection 616-81506 Class Zz Plug Gage Set 82 Pc

Product Description

The VALUE COLLECTION 616-81506 is an 82-piece Class ZZ plug gage set covering a diameter range of 0.751 to 0.832 inches with a plus tolerance of 0.0002 inches (0.0002 mm). Plug gages are precision go/no-go inspection tools used to verify that a drilled, reamed, or bored hole falls within a specified dimensional tolerance. Class ZZ is a working-grade tolerance class suited for general inspection of production parts where moderate precision is required. This set is used by machinists, quality control inspectors, and toolroom technicians in manufacturing, job shop, and maintenance environments.

This set is applicable to inspection tasks in general manufacturing, metalworking, and fabrication shops. It covers a continuous range of hole sizes from 0.751 to 0.832 inches, making it practical for inspecting a variety of drilled and bored features in a single kit. The 82-piece configuration provides full coverage across the range without gaps, reducing the need to source individual gages. It is suitable for both production-floor use and toolroom quality checks.

Installation Notes

Plug gages are hand-operated inspection tools and do not require permanent installation. Store gages in the provided case and handle with clean, dry hands or lint-free gloves to prevent dimensional inaccuracies from contamination or thermal expansion. Gages should be periodically verified against a master reference standard in accordance with your facility quality management procedures. Consult applicable metrology standards for gage calibration intervals and handling protocols.
