A Granite Square is a precision measuring tool used for
checking the squareness and flatness of objects, ensuring that they are at a
precise 90-degree angle. Made from high-quality granite, these squares are
valued for their stability, durability, and resistance to corrosion, making them
ideal for high-accuracy work in metrology, inspection, and machining
environments.

Benefits:

• Non-Magnetic: Being non-magnetic, granite squares do
  not attract metal chips, which can help maintain a clean measuring surface.
• Long-lasting: Due to their hardness and resistance to
  wear, they provide a longer service life compared to metal squares.

Overall, granite squares are essential tools in precision measurement,
providing consistent and reliable results in demanding environments where
accuracy is paramount.
