Spi 19-233-6 Class Zz Minus Plug Pin Gage 0.2330 in

Product Description

The SPI 19-233-6 is a Class ZZ minus plug pin gage designed to verify bore and hole diameters with high dimensional accuracy. Built from steel, it checks a nominal diameter of 0.2330 inches with a minus tolerance of 0.0002 inches, ensuring the gage falls below the nominal dimension as required by Class ZZ minus standards. This type of go/no-go gage is a standard tool in dimensional inspection work, used by machinists, quality control technicians, and precision measurement professionals to confirm that drilled, reamed, or bored features meet print tolerances before parts move to the next stage of production.

Plug pin gages in this size range are commonly used in general manufacturing, toolroom inspection, and incoming quality inspection environments. The 0.2330-inch diameter suits a range of close-tolerance holes found in machined components across metal fabrication, hydraulic valve bodies, and mechanical assemblies. This gage is a single-end, single-size instrument intended for hand-use inspection on the shop floor or in a controlled measurement lab.

Key Features

• Class ZZ minus tolerance of 0.0002 inches for below-nominal dimensional verification
• Nominal measurement diameter of 0.2330 inches
• Steel construction for durability in production inspection environments
• Lightweight at 0.2 pounds, suited for frequent hand-use inspection
• Single-size plug format for straightforward go/no-go hole checking

Compatibility

Designed as an OEM-style replacement or direct-fit inspection gage for applications requiring a Class ZZ minus plug pin gage at 0.2330 inches nominal diameter.

Installation Notes

Plug pin gages are handled and used by quality control technicians and machinists; no power tools or electrical shutoff is required. Clean the gage and the bore to be checked before use to prevent debris from affecting measurement accuracy. Do not force the gage into a hole — excessive insertion force can damage both the gage and the workpiece. Store in a protective case away from temperature extremes to maintain calibration integrity.
