Spi 19-268-2 Class Zz Minus Plug Pin Gage 0.268 in

Product Description

The SPI 19-268-2 is a Class ZZ minus plug pin gage machined from steel, designed for go/no-go gauging of hole diameters in precision inspection and quality control applications. It measures 0.268 inches in diameter with a minus tolerance of 0.0002 inches, conforming to Class ZZ standards for dimensional verification. This type of gage is used to confirm that a drilled, reamed, or bored hole falls within an acceptable size range. Machinists, toolroom technicians, and quality control inspectors rely on pin gages like this one for fast, repeatable hole measurement without the need for complex measurement instruments.

Class ZZ plug pin gages are standard tools in manufacturing, fabrication, and inspection environments. The 0.268-inch size fits a specific range of hole inspection tasks common in mechanical assembly and machining operations. This gage is appropriate for use in both production floor and inspection room settings where verifying hole size conformance is part of standard workflow. It is a single-end design sold individually and is suited for low-volume inspection or toolroom use where Class ZZ tolerance range is acceptable.

Key Features

• Class ZZ minus tolerance specification: 0.0002 inches for reliable dimensional verification
• 0.268-inch nominal diameter for precise hole gauging at that size
• Steel construction for durability and dimensional stability during repeated use
• Lightweight at 0.2 pounds, easy to handle during bench or in-line inspection
• Sold individually, suitable for toolroom and spot-check inspection applications

Compatibility

Designed as a standard Class ZZ minus plug pin gage for use in go/no-go inspection of 0.268-inch nominal diameter holes in machined or fabricated components.

Installation Notes

Pin gages are handled and used by machinists and quality control technicians following standard metrology practices. Store the gage in a protective case or roll when not in use to prevent surface damage that could affect accuracy. Clean the gage pin and the hole being inspected before use to remove chips, oil, or debris that could produce false readings. Do not force the gage into a hole; if resistance is felt, the hole is undersized and the gage should be withdrawn without applying excessive pressure.
