Vermont Gage 141237520 Class X Minus Pin Gage

Product Description

The VERMONT GAGE 141237520 is a Class X Minus pin gage designed for precise dimensional measurement and inspection work. It measures 0.3752 inches in diameter with a tolerance of -0.00004 inches, placing it in the tight-tolerance Class X specification tier. The gage is 2 inches long and features a 4 micro surface finish, making it suitable for verifying bore diameters, checking hole sizes, and calibrating measuring equipment. Manufactured from tool steel, this pin gage delivers the hardness and dimensional stability required for repeated use in a production or calibration lab environment. A Certificate of Accuracy with NIST traceability is included.

This pin gage is used in metrology labs, quality control departments, and precision machining environments where verifying part dimensions against a known standard is required. It is appropriate for both direct part gaging and calibration of measuring instruments. Technicians and quality inspectors working in manufacturing, aerospace, automotive, and general industrial trades rely on Class X pin gages for high-accuracy go/no-go and calibration applications.

Key Features

• Class X Minus tolerance: -0.00004 inches for high-precision measurement
• 0.3752 inches diameter for direct bore and hole inspection
• 2 inches working length for standard depth access
• 4 micro surface finish for consistent, repeatable contact
• Tool steel construction for hardness and dimensional stability

Compatibility

Designed for use in calibration of measuring equipment and direct part gaging applications where a Class X Minus pin gage at 0.3752 inches diameter is specified.

Installation Notes

Pin gages should be handled with clean, dry hands or cotton gloves to prevent corrosion from skin oils. Store in the provided case when not in use to protect the precision ground surface. Always verify that the gage and the part being measured are at the same ambient temperature before taking a measurement to avoid thermal expansion errors. Calibration and use should be performed by a qualified metrologist or quality technician in accordance with applicable inspection procedures.
