Vermont Gage 112413850 Class Zz Minus Plug Pin Gage 13.85 Mm

Product Description

The VERMONT GAGE 112413850 is a Class ZZ minus plug pin gage machined from steel and used to perform NoGo inspection of bored, drilled, or reamed holes at a nominal diameter of 13.85 mm. With a tolerance of 0.00508 mm, this gage confirms that a hole has not been opened beyond the maximum allowable dimension, making it a reliable go/no-go decision tool for production and quality control environments. Each unit ships with a Certificate of Accuracy traceable to NIST, supporting documented inspection requirements. Machinists, quality technicians, and toolroom professionals are the primary users of this type of gage.

This plug pin gage is suited for use in machine shops, manufacturing facilities, and metrology labs where hole diameter verification is part of a standard inspection process. It is designed for use alongside set micrometers, verniers, and other measuring devices as part of a complete dimensional verification workflow. The 2-inch overall length provides adequate reach for most standard workpiece configurations encountered in typical production inspection tasks.

Key Features

• Class ZZ minus tolerance class - intended for NoGo inspection of hole diameters
• 13.85 mm nominal measurement diameter with 0.00508 mm tolerance
• Steel construction for durability and dimensional stability in shop environments
• 2-inch overall length for practical reach in standard inspection setups
• Includes Certificate of Accuracy with NIST traceability for documented quality programs
• 10 micro coating/finish for surface protection and consistent gage performance

Compatibility

Designed for use with set micrometers, verniers, and other measuring devices in NoGo hole inspection applications requiring a 13.85 mm nominal diameter plug pin gage.

Installation Notes

Plug pin gages are handled and used by quality technicians and machinists - no installation in the traditional sense applies. Before use, clean both the gage and the workpiece bore to remove chips, coolant, and debris that could cause false readings or surface damage. Never force a plug gage into a hole; if resistance is felt, the hole is undersized or a burr is present. Store the gage in its protective case when not in use to preserve the surface finish and dimensional integrity.
