Spi 22-195-2 Class Zz Plug Gage Set 75 Pc 21-22.48mm

Product Description

The SPI 22-195-2 is a Class ZZ plug gage set covering a diameter range of 21.000 mm to 22.480 mm, with a plus tolerance of 0.005 mm per gage member. The set contains 75 pieces, providing incremental coverage across the full range for go/no-go inspection work in manufacturing and machining environments. Class ZZ designates a working-grade tolerance class suited for production floor inspection rather than master or reference standards. Machinists, quality technicians, and tool-room personnel use sets like this to verify bore diameters on machined parts, castings, and fabricated components to drawing tolerance.

This plug gage set is used in precision measurement applications where bore diameter verification is required across a tightly stepped range near 21 to 22.48 mm. Typical installation scenarios include incoming inspection stations, in-process quality checks on CNC-machined bores, and final inspection of production runs. The set is appropriate for both job-shop and high-volume manufacturing environments where consistent, traceable bore measurement is required.

Key Features

• Class ZZ working-grade tolerance for production floor inspection use
• Plus tolerance of 0.005 mm per gage member for consistent go/no-go verification
• 75-piece set covers 21.000 mm to 22.480 mm in incremental steps
• Broad range coverage reduces the need for multiple individual gages
• UNSPSC Code 41111600 for procurement and catalog classification

Compatibility

Designed as a working-grade plug gage set for bore diameter inspection of machined components requiring measurement in the 21.000 mm to 22.480 mm range.

Installation Notes

Plug gages should be handled and stored by quality or metrology personnel following established gage control procedures. Clean bores and gage members before use to prevent debris from affecting measurement accuracy or causing gage wear. Gages should not be forced into a bore; apply only light, consistent hand pressure to avoid damage to the gage or the workpiece. Periodic calibration and inspection per your facility's gage control program is recommended to maintain measurement integrity.
