Bolt type safety anchor shackles can be used in applications where round pin or screw pin shackles are used. However, a bolt type shackle is a better choice in permanent or long-term applications, or if there's a risk of a load sliding on the shackle pin, causing it to rotate.
We have a mature production process from raw materials to forging, heat treatment, machining,
surface treatment, etc. The materials include carbon steel, alloy steel, stainless steel, aluminum
Screw pin anchor shackles (also known as a screw pin bow shackle) are designed to offer the security of a strong connection with the ease of a quick release pin. The bow shape has the ability to handle a wider variety of connections and multi-dimensional pulling, as opposed to chain shackles (also called D shackles) which have a more narrow profile and are meant to be used for straight line pulls.
