The eyebolt is an important standard fastener widely used in the electromechanical field. Its main function is to lift loads. The eyebolt is usually forged from alloy steel. After normalizing and hardness testing, the hardness value reaches HRB67~95, which belongs to the 12.9 grade high-strength bolt. The eyebolt is widely used in many industries such as ports, electricity, steel, shipbuilding, petrochemicals, mining, railways, and construction. It is mainly used to connect slings and other mechanical equipment to ensure the safety and efficiency of lifting objects.
