Value Collection 616-81126 Class Zz Plug Gage Set 190 Pc

Product Description

The VALUE COLLECTION 616-81126 is a Class ZZ plug gage set designed for dimensional inspection of drilled, reamed, and bored holes across a measurement range of 0.0615 to 0.2505 inches. With a plus tolerance of 0.0002 inches (0.0002 mm), this set conforms to Class ZZ standards, which are appropriate for general-purpose inspection work where high-production or working-grade accuracy is required. The 190-piece set gives inspectors and machinists broad coverage across the specified diameter range without switching to a separate set. It is used by quality control technicians, machinists, and tool room personnel.

This plug gage set is suited for use in machine shops, manufacturing facilities, and inspection departments performing incoming, in-process, or final dimensional checks. The wide diameter range and 190-piece count make it practical for facilities that inspect a variety of hole sizes on a regular basis. It is commonly used to verify hole diameters on metal components produced by drilling, reaming, or boring operations, and is appropriate for both light and medium production inspection environments.

Installation Notes

Plug gages are handled and used by quality control technicians and machinists rather than installed into a system. Gages should be stored in their case when not in use to prevent damage to the precision ground surfaces. Clean all gages before and after use with a lint-free cloth to remove oils, chips, and debris that could affect measurement accuracy. Do not force a plug gage into a hole — if resistance is felt, the hole is undersize and forcing the gage may damage the gage or the part.
