Vermont Gage 141187450 Class X Plus Pin Gage

Product Description

The VERMONT GAGE 141187450 is a Class X Plus precision pin gage designed for high-accuracy dimensional inspection work. It measures 0.8745 inches in diameter and 2 inches in length, manufactured from tool steel with a 4 micro finish. The Class X Plus tolerance grade holds to a positive tolerance of 0.00004 inches, making it suitable for applications where measurement accuracy is critical. Each gage ships with a Certificate of Accuracy that includes NIST traceability documentation. Metrologists, quality technicians, and tool room personnel use pin gages of this grade to verify bore sizes, check slot widths, and calibrate measuring equipment on the shop floor or in a calibration lab.

This pin gage is used in manufacturing inspection, quality control, and calibration environments across industries including HVAC component production, precision machining, and industrial assembly. It is suited for both direct part gaging and for verifying or calibrating other measuring instruments. The 2 inch length provides adequate handling clearance for most standard inspection setups. Applications include checking bored holes, verifying tooling dimensions, and confirming tolerance conformance on finished or in-process parts.

Key Features

• Class X Plus tolerance grade: positive tolerance of 0.00004 inches for high-precision inspection

Compatibility

Designed for use as a precision reference gage in calibration of measuring equipment or for direct gaging of parts requiring a 0.8745 inch nominal bore or slot dimension.

Installation Notes

Pin gages are handled and used by quality technicians and metrologists; no permanent installation is required. Store the gage in its case when not in use to protect the finished surface from damage or contamination. Clean the gage and the part surface before measurement to prevent debris from affecting readings. Follow your facility calibration management procedures and applicable metrology standards when using NIST-traceable reference tools.
