Hook tip loading is a common problem. While reading through one of our catalogs, Brian ran across our instructions and asked the following question,  “What does it mean to never insert a hook tip?”

Peter answers:

Hooks typically do not fit into an eyebolt or they don’t seat properly in the saddle of the hook.  This can cause side loading and weaken the strength of the eyebolt.  Inserting a hook directly into the eye of the bolt often results in “Tip Loading.”   A “tip load” would be any load on a hook that is not entirely or wholly seated in the saddle of the hook.  Tip loading subjects the hook to an overload and is never acceptable. It is recommended that a shackle be used to connect a hook to any eyebolt to prevent any unnecessary stress. Please see the below illustration for the correct procedure.
