DESCRIPTION
The Planet Steel Squares are perfect for both general workshop tasks and engineering projects. They're crafted to accurately measure 90-degree angles. These squares meet the BS939 standard. The 8-inch size is designated as ES8.
To use this Planet Steel Square, simply place it against the edges you want to measure. It'll quickly show you if the angle is a perfect 90 degrees. When using it, make sure the square is firmly against the surfaces for an accurate reading. After each use, wipe it clean with a dry cloth to keep it in good condition. Store it in a dry place to prevent rusting. Don't drop it or subject it to heavy impacts as this could affect its accuracy.
