Vermont Gage 112202800 Class Zz Minus Plug Pin Gage 2.80mm

Product Description

The VERMONT GAGE 112202800 is a Class ZZ Minus plug pin gage machined from steel and used to perform NoGo inspection checks on precision bored holes and machined features. It measures 2.80 mm in diameter with a tolerance of 0.00508 mm, making it suitable for close-tolerance dimensional verification in production and quality control environments. The gage is 2 inches in overall length and features a 10 microfinish surface coating. Each unit ships with a Certificate of Accuracy traceable to NIST standards. Machinists, quality technicians, and tool room personnel use this type of gage to confirm that a hole or bore has not been oversized beyond allowable limits.

This pin gage is intended for NoGo inspection applications where confirming the upper boundary of a tolerance zone is required. Typical use cases include checking drilled, reamed, or bored holes in metal components on the shop floor or in a quality lab. It is also suited for setting and verifying micrometers, verniers, and other precision measuring devices where a known reference diameter is needed. The compact 2-inch length allows easy handling in confined fixtures and multi-gage setups.

Compatibility

Designed for use in NoGo inspection applications and as a reference standard for setting micrometers, verniers, and other precision measuring devices requiring a 2.80 mm reference diameter.

Installation Notes

Pin gages should be handled with clean, dry hands or lint-free gloves to prevent corrosion from skin oils. Store in the original case or a clean, dry environment away from abrasive materials that could damage the finished surface. No power tools or mechanical fasteners are required for use. Verify the gage surface is clean and undamaged before each inspection cycle to ensure measurement validity.
