Stainless Steel A4-80 Lifting Eye Nuts
The Stainless Steel A4-80 Lifting Eye Nut as per DIN 582 is a specific type of fastener designed for lifting and securing heavy loads. Let's break down its features, corrosion resistance, applications, and other relevant details:
Material and Grade:
Stainless Steel A4-80: The "A4" designation indicates that the nut is made from austenitic stainless steel, typically AISI 316 or 316L, which provides excellent corrosion resistance. The "80" in A4-80 denotes the minimum tensile strength in megapascals (MPa) of the material.

Features:
• Eye Nut Design: The DIN 582 standard specifies the dimensions and design of this eye nut. It features a threaded hole with a circular eyelet at the top for attaching hooks, cables, or other lifting equipment.
• Thread: The nut has a metric thread (M6, M8, M10, etc.) that corresponds to the size you need.
• Load Rating: These eye nuts are designed and rated for specific lifting capacities. Make sure to choose the appropriate size and grade based on your lifting requirements.
• Thread Type: It typically has a coarse thread, suitable for fastening to various lifting equipment.
Corrosion Resistance:
• The A4-80 stainless steel material offers exceptional corrosion resistance, making it suitable for use in corrosive environments, such as marine, chemical, or industrial settings.
• It is highly resistant to rust, oxidation, and many chemical agents, which makes it ideal for outdoor and underwater applications.
Applications:
• Lifting and Rigging: The primary application of DIN 582 eye nuts is for lifting and rigging operations. They are used in combination with shackles, hooks, and other hardware to secure and hoist heavy loads safely.
• Marine: Due to their corrosion resistance, stainless steel eye nuts are commonly used in marine and offshore applications, such as boat rigging and dock installations.
• Construction: They find use in construction for lifting steel beams, precast concrete elements, and other heavy materials.
• Industrial: These eye nuts are utilized in various industrial settings, including manufacturing, maintenance, and machinery handling.
