* 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
EDOM Section 5.7 , “Hooks - Stretch”.
