Spi 616-82952 Class Zz Plug Gage Set 0.201-0.3 in 100 Pc

Product Description

The SPI 616-82952 is a Class ZZ double-end plug gage set covering a diameter range of 0.201 to 0.3 inches in a 100-piece configuration. Each gage member is manufactured from steel and holds a tolerance of +0.0000 to +0.0005 inches with a minus tolerance type, conforming to Class ZZ standards. Sets like this are used to verify drilled, reamed, or bored hole diameters to close tolerances in production and inspection environments. Machinists, quality control technicians, and tool-room personnel are the primary users. The full set weighs 5.54 pounds and is packaged as a single unit.

This plug gage set is suited for incoming inspection, in-process quality checks, and final acceptance of machined parts where hole diameter conformance must be documented. The 0.201 to 0.3 inch range covers a common band of fractional and letter-size drill diameters frequently encountered in general metalworking, fabrication, and precision machining shops. Each gage is double-end design, providing both go and no-go members on a single handle for efficient pass-fail verification without changing tools.

Key Features

• Class ZZ tolerance classification for general-purpose inspection use
• Double-end design provides go and no-go members on each gage
• 100-piece set spans 0.201 to 0.3 inches in diameter coverage
• Tolerance range of +0.0000 to +0.0005 inches (minus tolerance type)
• Steel construction for durability in shop and inspection environments

Compatibility

Designed as a standard Class ZZ plug gage set for go and no-go inspection of machined holes in the 0.201 to 0.3 inch diameter range, compatible with general metalworking and quality inspection applications.

Installation Notes

Plug gages are handled and used by machinists and quality technicians and do not require installation in the conventional sense. Gages should be stored in their case when not in use to prevent damage to the lapped surfaces. Clean the gage members and the part bore before gauging to ensure accurate readings. Never force a plug gage into a bore; if it does not enter with light hand pressure, the hole is undersize.
