Vermont Gage 112101360 Class Zz Plus Plug Gage 1.36 Mm

Product Description

The VERMONT GAGE 112101360 is a Class ZZ Plus plug gage designed for precision go inspection of small-diameter bores and holes. Machined from tool steel and finished to a 10 microfinish surface quality, this pin-style gage delivers reliable dimensional verification with a tolerance of 0.00508 mm. At 1.36 mm in diameter, it fits the fine-tolerance measurement work common in machining, toolmaking, and quality control environments. Each unit ships with a Certificate of Accuracy traceable to NIST, meeting ASME B89.1 standards. Metrologists, machinists, and quality technicians use this gage to confirm hole acceptance without ambiguity.

This plug gage is suited for go inspection of precision-drilled or reamed holes in manufacturing and metrology settings. It is also used to set micrometers, verniers, and other measuring devices requiring a calibrated reference. The 1.36 mm diameter targets applications where extremely fine bore tolerances must be verified, such as in instrument manufacturing, medical device components, and precision mechanical assemblies. The overall length of 2.0000 inches allows for comfortable single-hand use during bench or in-line inspection routines.

Key Features

• Class ZZ Plus tolerance rating with 0.00508 mm tolerance for high-accuracy go inspection
• 10 microfinish surface finish reduces measurement error and wear during repeated use
• Tool steel construction provides hardness and dimensional stability over time
• NIST-traceable Certificate of Accuracy included with each unit
• Conforms to ASME B89.1 dimensional gage standards
• Overall length of 2.0000 inches suits bench and handheld inspection workflows

Compatibility

Designed for use as a go plug gage reference in bore inspection applications and for setting micrometers, verniers, and other precision measuring devices requiring a calibrated 1.36 mm diameter reference standard.

Installation Notes

Plug gages are handled and used by quality technicians and machinists during inspection; no permanent installation is required. Store the gage in its protective case when not in use to prevent surface damage or contamination that could affect accuracy. Clean the gage pin and the bore being measured before use to prevent debris from causing false readings or premature wear. Calibration intervals should follow the facility quality management plan in accordance with applicable metrology standards.
