Vermont Gage 911215600 Class Zz Minus Plug Pin Gage 0.1560 in

Product Description

The VERMONT GAGE 911215600 is a Class ZZ Minus plug pin gage machined from steel with a black oxide finish. It measures 0.1560 inches in diameter with a tolerance of 0.0002 inches and an overall length of 2 inches. This pin gage is used to verify bore and hole dimensions to a NoGo inspection standard. Each unit ships with a Certificate of Accuracy traceable to NIST, confirming the gage meets Class ZZ dimensional requirements. Machinists, quality technicians, and inspection personnel rely on this type of gage for fast, reliable pass-fail dimensional verification in production and inspection environments.

This plug pin gage is suited for NoGo inspection applications where a hole or bore must fall within a defined maximum material condition. It is also used to set micrometers, verniers, and other measuring devices requiring a known reference diameter. The 0.1560-inch diameter makes it appropriate for small-bore work common in precision machining, tooling, and light manufacturing. The black oxide coating reduces light reflection during inspection and provides a modest level of corrosion resistance for shop floor use.

Key Features

• Class ZZ Minus tolerance of 0.0002 inches for NoGo inspection applications
• 0.1560-inch diameter, 2-inch overall length for small-bore dimensional checks
• Steel construction with black oxide finish for durability and low reflectivity
• Includes Certificate of Accuracy with NIST traceability
• Compatible with micrometers, verniers, and other precision measuring devices as a reference standard

Compatibility

Designed for use in NoGo bore inspection and as a setting reference for micrometers, verniers, and other precision measuring devices requiring a 0.1560-inch diameter reference.

Installation Notes

Pin gages are handled by quality technicians and machinists; no installation trade license is required, but proper metrology practices apply. Keep the gage clean and lightly oiled when stored to prevent corrosion on the steel body. Never force a pin gage into a bore — if resistance is felt, the bore is undersize and forcing will damage the gage or the workpiece. Store separately from cutting tools to avoid surface damage that could affect dimensional accuracy.
