The purpose of this study was to determine the relationship of the variables contained in the torque formula used by John Deere for threaded fasteners. The formula assumed the variables to be either constant or in a linear relationship. Since friction was a major factor in determining torque values for threaded fasteners and only a small amount of torque applied to the head of a cap screw resulted in clamp load, it seemed to be a big assumption that the torque coefficient for friction was a constant. By investigating this relationship, the industry may be able to gain a better understanding of the dynamics of torquing cap screws, and be able to provide a better product for the consumer.
