I-Type Precision Square

• Accuracy is JIS standard Grades 1 and 2.
• It maintains high accuracy as a JIS standard designated high grade square.
• Because it thick and balanced, stable measurement can be performed with it standing.
• Use for measurement of tools perpendicularity, and squareness of parts attached using jigs, products squareness, etc
• It maintains enough accuracy for use as master in precision machinery as well as measuring instruments.
• All sizes are hardened.
• We can also manufacture similar products with special measurement and precision requirements.
