Stainless Steel A2-70 Lifting Eye Nuts, compliant with the DIN 582 standard, are specialized fasteners designed for lifting and rigging applications. These eye nuts are crafted from AISI 304 stainless steel with specific mechanical properties and corrosion resistance characteristics. Here are key features, applications, and considerations for these lifting eye nuts:


Material and Grade: Stainless Steel A2-70 Lifting Eye Nuts are typically manufactured from AISI 304 stainless steel. The "A2-70" designation indicates the material grade and its mechanical properties. "A2" refers to AISI 304 stainless steel, which contains 18% chromium and 8% nickel. The "70" denotes the minimum tensile strength, approximately 700 MPa, making these eye nuts suitable for various applications.

Design and Function: Lifting Eye Nuts according to DIN 582 have a threaded circular body with an integral looped eyelet. The threaded portion is designed to screw onto a compatible bolt or threaded rod, while the eyelet provides a secure anchor point for attaching lifting equipment, cables, or hooks. This design ensures a stable and reliable connection, making them suitable for lifting and suspending heavy loads.


Applications: Stainless Steel A2-70 Lifting Eye Nuts are commonly used in lifting, rigging, and suspension applications across various industries, including construction, maritime, and manufacturing. They serve as essential components for hoisting machinery, equipment, and heavy loads, especially in scenarios where corrosion resistance and dependable load-bearing capabilities are required.

Corrosion Resistance: AISI 304 stainless steel provides good corrosion resistance, making A2-70 Lifting Eye Nuts suitable for use in a range of environments. However, for highly corrosive conditions, such as those involving saltwater or chemical exposure, higher-grade stainless steels like AISI 316 (A4-70) may be more appropriate. Routine maintenance and inspection are essential to ensure their durability in challenging environments.


Safety Considerations: When using A2-70 Lifting Eye Nuts for lifting purposes, it is crucial to follow proper installation procedures and adhere to load rating guidelines. Ensure that the eye nut is securely fastened to a load-bearing structure and can safely handle the expected load capacity. Regular inspections are vital to verify that the eye nuts are free from defects and remain in good working condition.
