Stainless Steel with Galvanized Coating: The combination of stainless steel substrate and zinc coating provides enhanced corrosion protection. This dual-layer defense extends service life in environments where moisture, salt, or chemicals are present, supporting reliability in rigging operations.
Metric Thread Range M8-M30: The available size range accommodates various load requirements and attachment configurations. The M8 through M30 thread sizes allow engineers and rigging specialists to select appropriate eye screws for specific load capacities and structural connections.
Rolled Thread Construction: The thread rolling process improves fatigue resistance by creating a work-hardened surface and continuous grain structure. This manufacturing detail supports reliable performance in cyclic loading conditions common in lifting and rigging applications.
Round Head Eye Design: The smooth eye profile provides a consistent bearing surface for slings and hooks, reducing localized wear on lifting hardware. The eye diameter is sized for compatibility with standard shackles and lifting accessories.
Zinc Coating for Identification: The galvanized finish offers a visual indication of the product and provides additional corrosion protection, supporting extended service intervals.
Load Rating Consideration: The product design incorporates engineering factors appropriate for overhead lifting, supporting reliable performance when used within specified working load limits.
Versatile Application Compatibility: Suitable for use in food processing, marine, chemical, and general industrial environments, supporting a wide range of rigging and hoisting requirements.
Food Processing and Canning Machinery: In food processing facilities, these eye screws serve as lifting points for equipment maintenance, motor replacement, and component handling. The stainless steel construction provides a clean surface that supports hygiene protocols, while the galvanized coating adds durability in wet processing areas. The metric thread sizes accommodate various equipment mounting configurations.
Conveying Equipment: For conveyor systems, these eye screws are used as attachment points for lifting and positioning heavy components during installation and maintenance. The reliable thread engagement supports secure lifting of gearboxes, drive motors, and roller assemblies. The M8-M30 range provides options for different load requirements.
Medical Apparatus: In medical equipment manufacturing and facility maintenance, these eye screws support the safe handling of heavy diagnostic equipment, imaging systems, and patient handling devices. The corrosion-resistant properties support use in clinical environments where cleaning protocols are routine.
Packaging Machinery: Packaging lines often require regular maintenance access to heavy components. These eye screws provide dedicated lifting points that support safe and efficient equipment servicing. The galvanized finish offers good durability in packaging environments where dust and humidity may be factors.
Water Treatment and Chemical Equipment: In water treatment plants and chemical processing facilities, these eye screws serve as lifting points for pumps, valves, and large-diameter pipes. The corrosion-resistant construction supports reliable performance in environments where moisture and mild chemical exposure are routine considerations.
Ship Manufacturing and Marine Applications: In shipbuilding and marine maintenance, these eye screws are used for lifting and positioning equipment components, machinery, and structural assemblies. The stainless steel and galvanized coating provide enhanced resistance to saltwater corrosion, supporting long-term reliability in marine environments.
About Product
This lifting eye screw is a purpose-designed fastener for rigging and hoisting applications. The product is manufactured from stainless steel, providing a good baseline of corrosion resistance for industrial environments. The stainless steel construction is complemented by a galvanized (zinc) coating, which adds an additional layer of surface protection against oxidation and wear. This dual protection approach supports extended service life in applications where exposure to moisture, humidity, or mild chemicals is a consideration.
The eye screw features a round head design with a central hole that serves as the attachment point for lifting equipment. The eye geometry is engineered to accommodate standard lifting hooks, shackles, and synthetic slings. The internal diameter of the eye is dimensioned to allow free movement of the attachment hardware while maintaining sufficient material thickness around the hole for load-bearing integrity. The round head profile provides a smooth bearing surface that helps reduce wear on slings and attachment points.
The threaded shank is manufactured to metric standards, with sizes available from M8 through M30. The thread form is designed for engagement with corresponding tapped holes or threaded inserts in the load-bearing structure. The threads are rolled rather than cut, which improves fatigue resistance through work hardening and creates a continuous grain flow in the material. The thread pitch and tolerance are controlled to ensure consistent engagement and reliable load transfer.
For lifting applications, the eye screw must be selected with appropriate consideration of the working load limit. The load-bearing capacity is determined by the thread size, material grade, and the specific geometry of the eye. The design incorporates a safety factor appropriate for overhead lifting applications, meaning the breaking strength significantly exceeds the rated working load. The galvanized finish provides a degree of identification for the product and additional corrosion protection in demanding environments.
