* These values are nominal since the dimension is not controlled to a tolerance. The "k" dimension should be measured when the hook is
new - this becomes a reference measurement. Subsequent measurements are compared to this reference to make determinations about
hook deformation/stretch. See Section 4-5, “Hooks - Stretch”.
