Rigging | By Columbus McKinnon Training | Feb 01, 2019
“I have a concerned employee because we have some screw pin shackles with pins that do not protrude past the clevis when fully engaged. I have looked in several rigging books and cannot find any information on the threaded pin. We have other shackles from another manufacturer, and those pins extend approx 1/16″ past the end of the clevis. I know this sounds trivial, but we need to address every safety concern raised by our crew members. I would appreciate any information you could provide on shackle pin length.”
So, to answer your question: The threads do not need to extend beyond the shackle body.
It is good practice to obtain the latest copy of the ASME B30.26 standard for more information.
