Vermont Gage 911312650 Class Zz Plus Plug Gage 0.1265 in

Product Description

The VERMONT GAGE 911312650 is a Class ZZ Plus plug gage designed to measure bore and hole diameters with a nominal size of 0.1265 inches. Built from tool steel with a black oxide finish, it holds a tolerance of 0.0002 inches, making it suitable for precise go-inspection work in production and quality control environments. A Certificate of Accuracy with NIST traceability is included, confirming the gage meets the dimensional standards required for calibrated measurement tasks. Machinists, quality technicians, and metrology professionals use this type of gage to verify that drilled, reamed, or bored holes fall within accepted tolerance limits before parts advance through a production process.

This plug gage is intended for go inspection applications and is compatible with use alongside set micrometers, verniers, and other calibrated measuring devices. It is suited for light industrial and precision machining environments where tight hole tolerances must be confirmed on metal parts. The overall length of 2 inches keeps the gage easy to handle during repetitive inspection cycles. Manufactured to ASME B89.1 standards, it fits into standard gage-handling workflows where documented traceability back to NIST is a requirement for process control or customer audits.

Key Features

• Nominal measurement diameter of 0.1265 inches for precise small-bore inspection
• Class ZZ Plus tolerance of 0.0002 inches for controlled go-inspection accuracy
• Tool steel construction with black oxide finish for corrosion resistance and durability
• Meets ASME B89.1 dimensional standards
• Includes Certificate of Accuracy with NIST traceability for audit-ready documentation
• Overall length of 2 inches for easy single-hand operation

Compatibility

Designed for use in go inspection applications alongside set micrometers, verniers, and other calibrated measuring devices. Suitable as an OEM-style replacement or supplemental gage in standard plug gage sets for small-diameter bore inspection.

Installation Notes

Plug gages of this type are handled and used by quality technicians and machinists in inspection stations, not installed in equipment. Keep the gage clean and lightly oiled when not in use to prevent surface corrosion on the tool steel body. Do not force the gage into a bore; apply light, consistent hand pressure only. Store in a protective case away from temperature extremes to maintain dimensional stability and preserve the Certificate of Accuracy.
