Vermont Gage 111438150 Class Zz Minus Plug Pin Gage 0.3815 in

Product Description

The VERMONT GAGE 111438150 is a Class ZZ minus plug pin gage machined to a 0.3815-inch diameter for NoGo inspection work. It is a single-ended steel pin gage used to verify that a hole or bore does not exceed its maximum allowable dimension. Class ZZ is the standard tolerance grade for general shop-floor and inspection use. With a tolerance of 0.0002 inches and a 10 microfinish surface coating, the pin delivers consistent, repeatable results across dimensional verification tasks. Every unit ships with a Certificate of Accuracy traceable to NIST standards.

This plug pin gage is suited for production inspection environments and quality control stations where NoGo gauging is required. It is also used to calibrate or verify micrometers, verniers, and other measuring devices to confirm their accuracy against a known reference. The 2-inch overall length allows for comfortable single-hand operation in both bench-top and in-process inspection scenarios. Licensed metrologists, quality technicians, and machinists working in manufacturing, tool-and-die, and precision machining shops are the primary users of this type of gage.

Key Features

• Class ZZ minus tolerance grade for standard NoGo inspection applications
• 0.3815-inch diameter machined to a 0.0002-inch tolerance
• 10 microfinish surface coating for accurate, consistent contact
• Steel construction for durability in shop-floor conditions
• Includes Certificate of Accuracy with NIST traceability
• 2-inch overall length for practical single-hand use

Compatibility

Designed for use as a NoGo plug gage in standard bore and hole inspection, and for setting and verifying micrometers, verniers, and other precision measuring devices that accept a 0.3815-inch reference diameter.

Installation Notes

Plug pin gages do not require installation but should be handled and stored following standard metrology practices. Keep the gage clean and lightly oiled when not in use to prevent corrosion on the steel surface. Do not force the pin into a bore. If resistance is encountered during a NoGo check, the bore is within specification and no further insertion should be attempted. Calibration intervals should follow your facility quality management procedures.
