Vermont Gage 112417510 Class Zz Minus Plug Pin Gage 17.51mm

Product Description

The VERMONT GAGE 112417510 is a Class ZZ Minus plug pin gage designed for precise dimensional inspection of bores, holes, and internal features. Built from steel with a 10 micro-inch coating finish, this pin gage measures a nominal diameter of 17.51 mm and holds a tolerance of 0.00508 mm. At an overall length of 2 inches and a weight of 0.21 pounds, it is a compact, single-pin tool suited for use in quality control labs, machine shops, and production floor inspection. Each unit ships with a Certificate of Accuracy carrying NIST traceability, confirming that measurements are traceable to national standards.

This pin gage is intended for NoGo inspection applications where verifying that a feature does not exceed a maximum allowable size is required. It is also compatible with setting and checking micrometers, vernier calipers, and other precision measuring devices. The Class ZZ Minus designation indicates that the gage tolerance is held in the minus direction from nominal, which is appropriate for NoGo members in a go/no-go gage pair. Typical users include quality technicians, machinists, and metrology professionals working in both light manufacturing and precision machining environments.

Key Features

• 17.51 mm nominal measurement diameter with 0.00508 mm tolerance
• Class ZZ Minus tolerance class - suitable for NoGo inspection use
• Steel construction with 10 micro-inch coating finish for durability and wear resistance
• Includes Certificate of Accuracy with NIST traceability
• Compatible with micrometers, verniers, and other precision measuring devices
• Compact 2-inch overall length for easy handling in tight inspection setups

Compatibility

Designed for use in NoGo bore inspection applications and for setting and verifying micrometers, verniers, and other precision measuring devices. Suitable as a single-pin replacement or addition to an existing Class ZZ pin gage set.

Installation Notes

Pin gages should be handled by qualified quality control technicians or metrologists familiar with precision measurement procedures. Keep the gage clean and lightly oiled when not in use to prevent corrosion. Do not force the gage into a bore - light hand pressure only. Store in a protective case away from temperature extremes to preserve dimensional stability and NIST-traceable accuracy.
