Spring squareness refers to a compression spring, and how perpendicular it is, typically for ground ends. It is difficult to make the ends square within three degrees of a compression spring that is not ground flat.
The spring shown requires the ends to be within three degrees square which is a normal, commercial tolerance. Precision tolerances are less than three degrees, and many times require more labor hours to achieve precision squareness.
As shown in the picture, the compression spring is placed on a flat surface with a plate that is ninety degrees to the flat surface. The compression spring is then rotated on both ends to its widest gap from the spring end to the vertical plate. A formula is then used to calculate the squareness.
