Product details
Description
Ensure uncompromising quality control and precise hole dimensional accuracy in mechanical engineering and manufacturing with the Vermont Gage Steel No-Go Plug Gage. Built with a 0.1515-inch gage diameter and a Class ZZ tolerance limit of 0.0002 inches, this specialized cylindrical tool is engineered to verify whether drilled or machined holes exceed maximum allowable upper limits.
Crafted from cold-stabilized tool steel hardened to 60/64 Rockwell C scale, it delivers exceptional wear resistance, durability, and dimensional stability over long-term use. Each pin features a smooth 10-microinch or better surface finish, is round within 0.00001 inches per ASME B89.1.5 standards, and comes packaged with a volatile corrosion inhibitor to prevent rust.
Ideal for machinists, toolmakers, and quality assurance professionals seeking reliable calibration and inspection accuracy.
How to use
- Ensure the machined hole and plug gage are clean and at room temperature.
- Gently test the no-go gage against the hole; it should not enter a correctly sized hole, indicating the hole diameter is within allowable upper limits.
- Clean and apply a light coat of rust preventative oil before storing in a dry environment.

FAQs
What is a class zz pin gage?
A Class ZZ pin gage is a precision-machined cylindrical steel pin manufactured with a tight tolerance limit, specifically 0.0002 inches for inch-series gages. They are widely used in machine shops for inspecting hole sizes, checking locations, and setting measuring instruments.
What is the recommended tolerance for plug gauges?
The recommended tolerance depends on the manufacturing requirements and inspection stringency. Class ZZ is typically chosen for general shop floor inspection and quality control where standard precision is required.
What is the standard for no go thread gauge acceptance?
No-go gages are designed to test the upper limit or maximum material condition of a feature. In standard practice, a no-go plug gage should not enter or pass completely through a correctly machined hole during inspection.
Are these industrial tools authentic and imported from the USA?
Yes, this is an authentic Vermont Gage industrial product sourced directly from the USA, ensuring compliance with strict NIST calibration standards and reliable engineering performance.
How should I store my steel plug gage to prevent rust?
Keep the gage clean, handle it minimally to avoid moisture transfer from fingers, apply a light coat of rust preventative oil, and store it in a dry environment inside its protective packaging.
