Spi 19-626-1 Class Zz Minus Plug Pin Gage 0.626 in

Product Description

The SPI 19-626-1 is a Class ZZ minus plug pin gage used to verify hole diameters and internal dimensions in precision machining and inspection applications. This go/no-go style gage checks that a bored or drilled feature meets a specified minimum size. The 19-626-1 is manufactured from steel and holds a tolerance of 0.0002 inches, which is standard for Class ZZ minus gages used in general-purpose inspection work. At 0.2 pounds, it is a compact, hand-held tool suited for use on the shop floor or in a quality control environment. Machinists, tool and die makers, and QC inspectors are the primary users of this gage type.

This gage is sized for a 0.626-inch nominal diameter and is appropriate for inspecting holes and bores in metal, plastic, or composite workpieces where dimensional accuracy must be confirmed. Class ZZ minus gages are widely used in production environments where parts must be checked against tight dimensional standards before assembly or shipment. The minus designation indicates the gage is machined to the lower allowable limit of the nominal size, making it suitable for plug gage go-member applications in standard tolerance inspection routines.

Key Features

• 0.626-inch nominal diameter for precise internal dimension verification
• Class ZZ minus tolerance classification at 0.0002 inches for general-purpose inspection
• Steel construction for durability and wear resistance in production use
• Compact form factor at 0.2 pounds for easy one-hand operation
• Single-piece packaging with a minimum order quantity of one

Compatibility

Designed as an OEM-style replacement or direct-use plug pin gage for standard go/no-go gage handle sets accepting 0.626-inch diameter gage members in Class ZZ minus applications.

Installation Notes

Plug pin gages are installed and used by machinists or quality control technicians and require no power tools or permanent installation. Clean the gage and the feature being inspected before use to avoid measurement errors caused by debris or burrs. Handle the gage member carefully to avoid dropping, as impact can alter the calibrated surface and invalidate the tolerance. Gages should be periodically recalibrated per your shop's quality management procedures to confirm continued accuracy within the stated 0.0002-inch tolerance.
