Swing Eye Bolts

Swing Eye Bolt Product Describsion

Swing eye bolts are Boltead’s main product. We are a manufacturer of swing eye bolts and also a supplier of swing eye bolts. While producing and supplying swing eye bolts, we also produce nuts, washers and other fastener products used in conjunction with them.

The swing eye bolts we produce are generally classified according to whether the material is carbon steel or stainless steel. More specific classifications are as follows:

Carbon steel swing eye bolts are generally classified according to strength levels. The more common strength levels are: 4.8, 8.8, 10.9, and 12.9. Among them, bolts with grade 8.8 or above are generally called high-strength bolts （high tensile bolts）.Stainless steel swing eye bolts are generally classified according to different materials. The more common stainless steel materials are SUS201 SUS304 SUS316

In addition to different materials and strengths, the biggest impact on swing eye bolts is surface treatment. The following are the more common surface treatments for swing eye bolts: black oxide, black zinc, zinc plated (ZP), color zinc plating (CZP /YZP), hot dip galvanized (HDG), dacromet coating, etc.

Swing Eye Bolt Production Process

Swing eye bolts are sent from the raw material line to the final product. They generally go through the following process:
Annealing of raw materials – pickling – drawing – forming – grinding – heat treatment – surface treatment – classification – packaging – shipping

The rough schematic diagram is as follows:

Swing Eye Bolt Application fields

Examples of Uses of DIN444 Swing Eye Bolts:

1. Lifting and Rigging Operations: DIN444 swing eye bolts are commonly used in lifting and rigging applications where heavy loads need to be lifted, suspended, or secured. They provide a reliable attachment point for lifting equipment such as chains, slings, and hoists, allowing for safe and efficient handling of materials in construction sites, warehouses, and manufacturing facilities.
2. Industrial Machinery: These bolts are often utilized in industrial machinery and equipment for mounting components, securing covers, or attaching accessories. They can be used in conjunction with nuts and washers to provide a sturdy connection point in machinery assembly, maintenance, and repair processes across various industries, including automotive, aerospace, and manufacturing.
3. Marine and Shipbuilding: These bolts find applications in marine and shipbuilding industries for securing rigging hardware, lifelines, and safety equipment on boats, ships, and offshore structures. They are corrosion-resistant and can withstand harsh marine environments, making them suitable for use in saltwater conditions without compromising performance or safety.
4. Material Handling: These bolts are employed in material handling equipment such as cranes, hoists, and lifting beams to facilitate the movement and positioning of heavy loads. They are often installed in fixed locations or incorporated into lifting attachments to provide a secure anchorage point for lifting hooks or chains, ensuring stability and control during material handling operations.
5. Structural Support: These bolts are used in construction and structural engineering applications for anchoring structural elements, securing cables, or installing safety barriers. They can be embedded into concrete or attached to structural steel members to provide reliable anchorage points for supporting structures, facade systems, and safety equipment on buildings, bridges, and other infrastructure projects.
6. Temporary Rigging: These bolts are also utilized in temporary rigging setups for events, concerts, and theatrical productions. They provide a versatile and easily adjustable attachment point for suspending lighting fixtures, sound equipment, banners, and decorations, allowing for quick setup and teardown of rigging arrangements in event venues and entertainment spaces.

These examples illustrate the diverse range of applications for DIN444 swing eye bolts across various industries, emphasizing their versatility, durability, and reliability in providing secure anchorage and lifting solutions.
