What are Stainless steel shackle used for: 

Stainless steel shackle are perfect for tough environments & renowned for their durability and reliability. These shackle are the best choice for marine environments. Because it can protect the rigging operation as opposed to the effects of salt water. But these shackle are more expensive than any other types of steel shackle. Also, it is not suitable for general lifting where corrosion resistance is not needed.

What are Piling shackles used for: 

The piling shackles contain an extended D-shaped shank & there is a reason behind it! Because piling shackles are intended to lift steel piling sheets, whose anchor points are around 150mm distance from the top. Piling shackles are used for construction sites. As shackle are needed to maintain ground levels.

What are Screw pin shackle used for: 

A threaded pin is inserted through the ears of a screw pin & tightened down. Screw pin shackle are convenient for rigging that is used for “pick and place” applications. It can be used when side loading is present and with multi-leg sling gatherings. Keep in mind that, when a screw pin shackle is used, the screw pin threads need to be fully engaged, and tight, and the shoulder should be in contact with the shackle body.

What are Safety Shackles used for: 

Safety shackles are used in the construction and lifting industries. These are available in bow & D shackle shapes. But these are a bit different from the common ones because these contain a nut & pin which secures the fastening.
