Screw Pin Bow Shackles

A screw pin bow shackle is a type of fastening device used in rigging and lifting applications. It's designed to connect various components of lifting or rigging equipment together securely. Shackle types can vary based on their design and features, and a screw pin anchor shackle specifically has a removable screw pin or bolt that is used to secure the two ends of the shackle.

Here are some key points about a screw pin anchor shackle:

  • Design: A screw pin anchor shackle typically consists of a U-shaped metal body with a removable pin or bolt threaded through the ends of the "U." The pin has a threaded portion that screws into one side of the shackle body, and it can be easily screwed in or unscrewed by hand or using a tool.
  • Applications: Screw pin anchor shackles are commonly used in lifting and rigging applications where temporary connections are needed. They are used to connect various components like slings, hooks, and other lifting equipment.
  • Usage: To use a screw pin anchor shackle, you would unscrew the pin to open the shackle, then place the looped ends of the rigging components onto the shackle's body, and finally screw the pin back in to secure the connection. This makes them relatively easy to attach and detach.
  • Load Capacity: Screw pin anchor shackles come in various load capacities and sizes to accommodate different lifting and rigging needs. It's important to choose the right size and load capacity for the specific application to ensure safety.
  • Safety Considerations: Proper use and inspection are crucial when using any lifting or rigging equipment, including screw pin anchor shackles. Regular inspection for wear, deformation, or damage is essential to prevent accidents. It's also important to follow industry standards and guidelines for safe usage.
  • Alternative Designs: In addition to screw pin anchor shackles, there are other types of shackles available, such as bolt-type shackles with a captive bolt that can't be fully removed, and quick-release shackles with a lever mechanism for faster attachment and detachment.

Remember that safety is paramount when using any rigging or lifting equipment. Always follow proper procedures, guidelines, and regulations, and ensure that those using the equipment are properly trained. If you're unsure about the specific type of shackle to use or how to use it, it's recommended to consult with a qualified professional or engineer.
