Abstract
A golf club head having multiple structural columns is disclosed herein. A body comprises a face section, a sole section, and a crown or return section, and defines a hollow interior. Each of the structural columns extends from the crown or return section to the sole section within the hollow interior to reduce stresses placed on the face section during impact with a golf ball. The structural columns are all located within 1 inch of a rear surface of the face section measured along a plane normal to the center of the face, and are spaced a distance of 0.500 to 2.00 inch from one another within the hollow interior.
