Domestic vs. Foreign
It was mentioned above, but now itâ€™s time to break it down further. Many US contractors have started requiring shackles that are made domestically. A domestic shackle is a shackle that has been made in the United States. They are often preferred to foreign made shackles due to better manufacturing and testing processes. Crosby, one of the most popular shackle manufacturers in the world, has a full selection of domestically manufactured shackles to meet your needs no matter what the job site requires.
Screw Pin vs. Bolt Shackles
Each job is unique and that means requirements are different. Not to mention, contractors may have preferences in addition to requiring domestic shackles. Apart from common things like U-shape size and capacity, the main difference between shackles will be whether they are a screw pin or a bolt shackle.
Screw PinA screw pin shackle is pretty self-explanatory. It is a type of shackle where the pin has a male threaded end, which tightens into the female threads in the body of the shackle. These shackles are popular because of their ease of use and are most commonly used on jobs that donâ€™t require heavy duty attachment.
BoltA bolt shackle is pretty self-explanatory as well. It is a type of shackle where the pin has a male threaded end which is fed through the body of the shackle and secured with a bolt on the outside of the shackle. These shackles arenâ€™t as easy to use as the screw pin shackles because of the requirements of securing the bolt to the pin. However, bolt type shackles are typically a better solution for jobs that require heavy duty attachment.
Standards: ASME B30
When it comes to lifting and rigging, which happens to include shackles â€“ if youâ€™re using them in a lifting and rigging capacity, the ASME B30 StandardÂ is something that you need to be mindful of. The ASME B30 standard focuses on setting the standards for materials, rated loads, identification, inspection, repair, and removal. ASME B30 covers blocks and a range of other hardware used for lifting and rigging. We covered ASME B30 and provided a full breakdown of the standard in a previous blog post. You can find that post here.
