Vermont Gage 111415750 Class Zz Minus Plug Pin Gage 0.1575 in

Product Description

The VERMONT GAGE 111415750 is a Class ZZ Minus plug pin gage ground to a 0.1575-inch diameter for NoGo inspection work. Pin gages in this class are machined from steel and held to a tolerance of 0.0002 inch, making them suitable for verifying that a hole or bore does not exceed its maximum allowable size. Each unit ships with a Certificate of Accuracy traceable to NIST, confirming the gage meets dimensional requirements at the time of manufacture. The overall length is 2 inches. Machinists, quality technicians, and metrologists use these gages in production inspection, incoming material verification, and toolroom measurement routines.

Class ZZ Minus plug pin gages are used in applications where a go/no-go inspection protocol is required. This specific gage serves the NoGo function, rejecting parts whose bore diameter exceeds the specified limit. It is also appropriate for setting and verifying micrometers, verniers, and other measuring devices that require a traceable reference standard. Typical environments include machine shops, quality labs, and assembly lines where dimensional control of small-diameter bores is critical. The 0.1575-inch size falls in a range commonly encountered in precision machined components and fixture work.

Key Features

• Class ZZ Minus tolerance of 0.0002 inch for NoGo inspection accuracy
• 0.1575-inch measurement diameter ground to a 10 microfinish surface finish
• Steel construction for durability in production and toolroom environments
• Certificate of Accuracy included with NIST traceability
• 2-inch overall length provides adequate handling clearance for most fixtures
• Suitable for setting micrometers, verniers, and other calibrated measuring devices

Compatibility

Designed for use in NoGo bore inspection routines and as a reference standard for setting micrometers, verniers, and other measuring devices requiring a traceable 0.1575-inch reference.

Installation Notes

Pin gages are handled and stored by metrology or quality personnel following standard gage-care practices. Keep the gage clean and lightly oiled to prevent corrosion on the steel surface. Never force a pin gage into a bore; insertion should require only light hand pressure to avoid damaging the gage or the workpiece. Store in the original case or a protected gage stand to maintain the surface finish and dimensional integrity.
