Precautions:
1. When using the square, hold steady to ensure the accuracy of your measurements.
    If the hand is shaky it will cause the measurement results deviation.
2. The square needs to be handled with care during use to avoid collision or bending.
3. Squares available in different lengths and widths, so you should choose the right size when using them.
    If the workpiece is too large, you need to choose a bigger range. Conversely, if you need to measure small size,
    you should choose a relatively small range.
4. After use, the square should be cleaned and kept dry.

Applications:

The 90° square is mainly used in various industrial and engineering applications, it is
essential for machinists, engineers, and quality control professionals who require precise 
and reliable tools for their work.
