Lifting Eye Nuts
Lifting eye nuts must always be tightened so that they bear solidly on the surface they contact. Loads at right angles to the plane of the eye are prohibited.
When a specific position in relation to an axis, edge or the like is specified for the lifting eye nut when screwed on, shims should be used if necessary in order to rule out unacceptable loading.
