Product Features:
- 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 perpendicular, 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.
