Spi 616-62032 Class Zz Plug Gage Set 101 Pc 0.0787-0.1181 in

Product Description

The SPI 616-62032 is a 101-piece Class ZZ double-end plug gage set used to verify hole diameters with a range of 0.0787 to 0.1181 inches. Each gage member is manufactured from steel and holds a bilateral tolerance of plus or minus 0.002000 inches, conforming to Class ZZ standards for go/no-go inspection work. This set is suited for quality control and inspection tasks in production and maintenance environments. Machinists, toolmakers, and quality technicians use plug gage sets like this to confirm bore and hole sizes meet print tolerances without relying on indicating instruments.

This set covers small-diameter holes in the range of 2.000 to 3.000 millimeters (0.0787 to 0.1181 inches), making it appropriate for precision work on small bores in light manufacturing, toolroom inspection, and assembly verification. The double-end design allows a go and no-go member to be mounted on a single handle, reducing handling time during inspection. With 101 pieces in the set, the kit spans the full stated range at incremental steps for thorough diameter verification coverage.

Key Features

• Class ZZ tolerance grade for go/no-go hole inspection
• Bilateral tolerance of plus or minus 0.002000 inches per member
• Double-end configuration combines go and no-go on one handle
• Steel construction for durability and dimensional stability
• 101-piece set covers 0.0787 to 0.1181 inch diameter range
• Range also expressed as 2.000 to 3.000 millimeters for metric reference

Compatibility

Designed as a standard Class ZZ plug gage set for go/no-go inspection of small bores and holes in production and toolroom environments where diameters in the 0.0787 to 0.1181 inch range require verification.

Installation Notes

Plug gages are handled and used by machinists, toolmakers, and quality inspectors — no installation in the traditional sense applies. Store members in the provided case to prevent nicks and contamination that can affect dimensional accuracy. Clean gages before and after use with an appropriate solvent and apply a light coat of oil for corrosion protection during storage. Never force a gage member into a hole; if resistance is felt, the bore does not meet tolerance and forcing the gage risks damage to both the gage and the workpiece.
