Spi 22-190-3 Class Zz Plug Gage Set 250 Pc Nist

Product Description

The SPI 22-190-3 is a 250-piece Class ZZ plug gage set covering a diameter range of 5 to 9.98 mm with a plus 0.005 mm tolerance. It is used to measure hole sizes, slot widths, and distances between holes with consistent, repeatable accuracy. Each pin in the set conforms to Class ZZ tolerance standards and ships with a Certificate of Accuracy that is NIST traceable. A pin gage holder is included. The set is suited for inspection work in manufacturing, machining, and quality control environments where Go-gage inspection is part of standard workflow. Licensed metrologists, machinists, and QC technicians are the primary users.

This plug gage set is designed for quick and accurate measurement tasks across a wide range of bore and slot sizes in the 5 to 9.98 mm range. Typical applications include incoming inspection, in-process quality checks, and final inspection of machined components. The set supports Go gaging inspection workflows and is appropriate for use in production floor environments as well as dedicated metrology labs. The NIST traceable certification supports ISO and AS9100 quality management documentation requirements.

Installation Notes

Pin gages should be handled with clean, dry hands or lint-free gloves to prevent corrosion from skin oils. Store pins in the provided holder when not in use to protect the calibrated surfaces. Verify pins are clean and free of debris before use to ensure measurement accuracy. Consult the included Certificate of Accuracy and maintain calibration records in accordance with your quality management system requirements.
