Value Collection 616-81306 Class Zz Plug Gage Set 125 Pc

Product Description

The VALUE COLLECTION 616-81306 is a 125-piece Class ZZ plug gage set covering a diameter range of 0.501 to 0.625 inches. Each gage in the set is manufactured to a plus tolerance of 0.0002 inches, meeting Class ZZ standards for go/no-go inspection of drilled, reamed, and bored holes. This set is used for dimensional verification in machining and fabrication environments where consistent bore sizing is critical. Machinists, quality control technicians, and tool-room personnel rely on plug gage sets like this to confirm that finished bores fall within specification before parts move to assembly.

This set is suited for inspection work in job shops, production machining facilities, and quality assurance departments. The 125-piece configuration provides broad coverage across the 0.501 to 0.625 inch range, reducing the need for individually sourced gages across that span. It is appropriate for use on ferrous and non-ferrous workpieces wherever hole diameter verification is required as part of standard inspection protocol.

Key Features

• 125-piece set covering 0.501 to 0.625 inches in diameter
• Class ZZ tolerance classification with plus tolerance of 0.0002 inches
• Designed for go/no-go bore inspection in machining and fabrication applications
• Broad range coverage reduces need for individual gage procurement within the span
• Tolerance also expressed as 0.0002 mm for reference in dual-unit environments

Compatibility

Designed as a standard Class ZZ plug gage set for use with any bore or hole inspection application requiring diameter verification within the 0.501 to 0.625 inch range.

Installation Notes

Plug gages are handled and used by machinists and quality control technicians, not installed in the traditional sense. Before use, clean the gage and the bore thoroughly to remove chips, coolant, and debris that could cause false readings or surface damage. Never force a plug gage into a bore; forced insertion can damage the gage and compromise its accuracy. Store gages in their case and away from temperature extremes to maintain dimensional stability.
