Spi 616-82932 Class Zz Plug Gage Set 100 Piece

Product Description

The SPI 616-82932 is a 100-piece Class ZZ double-end plug gage set covering a diameter range of 0.101 to 0.200 inches. Each gage is manufactured from steel and holds a minus tolerance of 0.000000 to 0.000500 inches, meeting Class ZZ specifications for go/no-go inspection of drilled, reamed, or bored holes. The double-end design places the go member on one end and the no-go member on the other, reducing handling time during inspection. This set is used by machinists, quality control technicians, and toolroom personnel for in-process and final inspection of hole diameters in production and job-shop environments.

The 616-82932 is suited for dimensional verification in manufacturing environments where Class ZZ tolerances are specified. The 100-piece set spans the 0.101 to 0.200 inch range in incremental steps, making it a practical single-purchase solution for shops that inspect a wide range of small-bore hole sizes. Typical applications include aerospace, automotive, and general metalworking where accurate bore qualification is required before assembly.

Key Features

• Class ZZ tolerance: 0.000000 to 0.000500 inches (minus tolerance type)
• Full 100-piece set covering 0.101 to 0.200 inches diameter range
• Double-end configuration provides go and no-go members on a single gage handle
• Steel construction for wear resistance and dimensional stability
• Incremental diameter steps reduce the need for multiple separate gage purchases

Compatibility

Designed as a standard Class ZZ plug gage set suitable for go/no-go inspection of holes in the 0.101 to 0.200 inch diameter range per applicable gage tolerance standards.

Installation Notes

Plug gages are handled and used by qualified inspection personnel or machinists; no power tools or utilities need to be shut down for standard gage inspection work. Store gages in the provided case and apply a light coat of rust-preventive oil when not in use to maintain accuracy. Avoid dropping or forcing gages through undersized holes, as impact can alter the gage diameter and invalidate measurements. Periodic calibration against a traceable standard is recommended to verify continued accuracy.
