Product details
Description
The Vermont Gage Steel Go Plug Gage is a high-precision cylindrical measuring instrument engineered for accurate hole sizing and quality control in industrial machining environments. Featuring an exact 0.428 inch diameter with a Class ZZ positive tolerance, this tool is ideal for inspecting the lower limit of drilled or machined holes and setting precision measuring equipment.
Constructed from cold-stabilized tool steel, the gage offers exceptional durability, maintaining a 60 to 62 Rockwell C hardness and a smooth 10-microinch surface finish for reliable, repeatable performance. Each unit includes a certificate of accuracy traceable to NIST standards, making it an essential addition to professional toolrooms and manufacturing floors requiring strict dimensional verification.
How to use
- Clean the gage and the target hole thoroughly before measurement.
- Insert the Go plug gage gently into the hole without applying excessive force.
- If the gage enters smoothly under its own weight or light finger pressure, the hole meets or exceeds the minimum allowable lower limit.

precise measurement pin
Picked this up for checking hole sizes in our workshop machining setup. The cold-stabilized tool steel feels really solid and durable for regular use. Measures right on point and the surface finish is smooth so it goes in without any binding. NIST traceable cert was a nice bonus for our quality checks.
FAQs
What is the tolerance of a Class ZZ gage pin?
A Class ZZ gage pin features a tolerance of plus 0.0002 inches and minus 0.0000 inches, providing precise dimensional control for standard workshop inspection and calibration tasks.
How to size a go no-go gauge?
Go and No-Go gauges are sized according to the upper and lower dimensional limits of a mating part. The Go gage checks the minimum material boundary of a hole, while the No-Go gage verifies that the maximum limit is not exceeded.
What are the different classes of gage pins and what are their tolerances?
Gage pins come in several classes including XX, X, Y, Z, and ZZ, with tolerances ranging from ultra-precision limits of plus or minus 0.00002 inches up to 0.0002 inches for Class ZZ, depending on the required precision level.
