Spi 19-065-2 Class Zz Minus Plug Pin Gage 0.065 in

Product Description

The SPI 19-065-2 is a Class ZZ minus plug pin gage with a 0.065-inch nominal diameter, manufactured from steel for consistent dimensional measurement in production and inspection environments. Class ZZ is the standard tolerance grade for go/no-go gage work in general manufacturing and quality control. The minus designation means the gage is ground below nominal, making it a go-member in a standard plug gage application. With a tolerance of 0.0002 inches, this gage provides reliable pass/fail verification of hole diameters in machined and fabricated components. It weighs approximately 0.2 pounds.

This pin gage is used wherever small-hole inspection is required, including machining operations, production floor QC checks, and inspection lab environments. It is suited for verifying drilled, reamed, or punched holes in metal, plastic, and composite workpieces. Machinists, quality technicians, and tool and die professionals use Class ZZ pin gages for routine go/no-go inspection of holes in the small-diameter range. The 0.065-inch size is common in precision sheet metal, electronics hardware, and light mechanical assemblies.

Key Features

• Class ZZ tolerance grade for general-purpose go/no-go inspection
• Minus designation confirms below-nominal grind for go-member use
• 0.0002-inch tolerance for precise dimensional verification
• Steel construction for durability and dimensional stability
• 0.065-inch nominal diameter covers small-hole inspection requirements

Compatibility

Designed for use as an individual pin gage or as a replacement member in standard plug gage handle sets that accept 0.065-inch diameter Class ZZ minus pins.

Installation Notes

Pin gages should be handled with clean, dry hands or cotton gloves to prevent corrosion from skin oils. Store in the provided case or a padded gage tray away from cutting tools and abrasive surfaces. When inserting the pin into a hole, apply light axial pressure only — never force or rotate the gage, as this will accelerate wear and compromise accuracy. Gages should be recalibrated periodically in accordance with your facility quality system and applicable metrology standards.
