Vermont Gage 141228600 Class X Minus Pin Gage 0.286 in

Product Description

The VERMONT GAGE 141228600 is a Class X Minus tolerance pin gage designed for precision dimensional inspection in tool rooms, calibration labs, and production floor environments. Manufactured from tool steel with a 4 microinch surface finish, this pin gage measures 0.286 inches in diameter and 2 inches in length. It carries a negative tolerance of 0.00004 inches, conforming to Class X Minus standards. Each unit ships with a Certificate of Accuracy backed by NIST traceability, making it suitable for documented metrology programs. Dimensional inspection technicians and quality control professionals are the primary users.

This pin gage is used to verify bore diameters, hole sizes, and feature dimensions in machined parts during incoming inspection, in-process gauging, or final acceptance testing. It is equally applicable to calibration of measuring equipment where a traceable reference standard is required. Common settings include aerospace, automotive, and general manufacturing facilities where tight dimensional tolerances must be confirmed. The 2-inch length provides adequate handling clearance for most standard inspection fixtures and handheld use.

Key Features

• Class X Minus tolerance at -0.00004 inches for high-precision go/no-go or reference gauging
• Tool steel construction for durability and dimensional stability under repeated use
• 4 microinch surface finish for accurate, repeatable contact measurements
• Includes Certificate of Accuracy with NIST traceability for documented calibration programs
• Compact 2-inch length suits standard inspection fixtures and handheld applications

Compatibility

Designed as an OEM-style Class X Minus pin gage for use in calibration of measuring equipment or direct part gauging applications where a 0.286-inch nominal diameter reference standard is required.

Installation Notes

Pin gages should be handled with clean, dry hands or lint-free gloves to prevent corrosion and dimensional contamination from skin oils. Store in the provided case or a protected environment when not in use to maintain surface finish integrity. No special tools are required for use, but periodic recalibration against a traceable standard is recommended per your quality management system requirements. Do not force the pin gage into a feature; free passage or contact should occur under its own weight or light hand pressure only.
