Vermont Gage 111299600 Class Zz Minus Plug Pin Gage 0.9960 in

Product Description

The VERMONT GAGE 111299600 is a Class ZZ Minus plug pin gage designed for precision dimensional inspection in machining and manufacturing environments. It measures a nominal diameter of 0.9960 inches with a tolerance of 0.0002 inches, making it suitable for NoGo-side inspection checks where accurate rejection of oversized bores is critical. Constructed from steel, this pin gage delivers the rigidity needed for repeatable contact measurement. Each unit ships with a Certificate of Accuracy traceable to NIST standards, supporting quality documentation requirements in regulated production settings. Machinists, quality technicians, and metrologists are the primary users of this tool.

This plug pin gage is used in machine shops, toolrooms, and quality control departments to verify that bored, reamed, or drilled holes do not exceed allowable tolerances. As a NoGo gage, it confirms that a hole has not been machined oversize. It also serves as a reference standard for setting micrometers, verniers, and other measuring devices where a known cylindrical reference of 0.9960 inches is required. Suitable for both job-shop and production-floor use wherever Class ZZ tolerance gage accuracy is specified.

Key Features

• Class ZZ Minus tolerance designation for NoGo plug inspection applications
• Nominal measurement diameter of 0.9960 inches with 0.0002 inch tolerance
• Steel construction for durability and dimensional stability
• 10 micro-inch finish coating for consistent surface contact
• Includes Certificate of Accuracy with NIST traceability for documentation compliance
• Overall length of 2 inches for easy handling in standard gage fixtures

Compatibility

Designed for use in NoGo bore inspection applications and as a setting reference for micrometers, verniers, and other precision measuring devices requiring a 0.9960 inch diameter cylindrical standard.

Installation Notes

Pin gages are handled and used by quality technicians and machinists familiar with gage calibration practices. Keep the gage clean and lightly oiled when not in use to prevent corrosion on the steel surface. Do not force the gage into a bore; apply only light hand pressure to avoid false readings or gage wear. Store in a protective case away from temperature extremes to maintain dimensional stability.
