- ISO thread - Material: Black stamped steel Mounting - For safe and correct assembly: Chamfer the hole into which the bolt will screw or use washers to ensure correct seating. - Before assembly, clean the threads and corresponding tapped holes - Screw lifting eye in fully - The load should be lifted in the direction of the thread, +/- 20° and the pulling force should be along the axial plane of the eye. - The use of these lifting eyes at an angle greater than 45° is not allowed. - When the load to be lifted is aluminium, avoid leaving the eyes screwed in for long periods to avoid possible corrosion Info SWL: SAFE WORKING LOAD The Safe Working Load is calculated by dividing the Breaking Strength by a factor of safety of 5.
