Vermont Gage 112401570 Class Zz Minus Plug Pin Gage

Product Description

The VERMONT GAGE 112401570 is a Class ZZ Minus plug pin gage used to verify bore and hole diameters to tight dimensional tolerances. It measures a nominal diameter of 1.57 mm with a tolerance of 0.00508 mm, making it suitable for NoGo inspection work where precise rejection of out-of-tolerance bores is required. The gage is machined from steel and features a 10 microfinish surface coating for consistent, accurate contact. At 2 inches in overall length, it is a compact, hand-held inspection tool used in quality control and dimensional verification workflows. Each unit ships with a Certificate of Accuracy traceable to NIST standards.

This plug pin gage is used in precision inspection environments including machine shops, manufacturing floors, and quality assurance labs. It is appropriate for NoGo inspection applications and can be used alongside set micrometers, verniers, and other measuring devices to confirm that bores fall within specified tolerances. The Class ZZ designation indicates a standard commercial-grade tolerance class suitable for general production inspection. Dimensional inspectors and machinists handling close-tolerance work will find this gage suitable for verifying small-diameter features in metal components.

Compatibility

Designed for use in NoGo inspection applications and compatible with set micrometers, verniers, and other measuring devices requiring a 1.57 mm diameter reference standard.

Installation Notes

Pin gages are handled and used by dimensional inspectors and machinists - no power tools or electrical shutoff procedures are required. Handle the gage 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 finish. Follow your facility's calibration and traceability procedures when placing this gage into service.
