Standard for Forged Hooks
Standard for Forged Hooks
(OP)
I work in the logistics and transportation industry. Does any on know of a standard the governs the hooks that are used on chains. The NACM seems to only have information on chains and nothing on the end hooks. Specifically I am looking to verify what markings need to be on the forged parts.
Thanks
Thanks

One of which, "RR-C-271D Federal Specification- Chains and Attachments, Welded and Weldless", does address hooks to some extent:

I still don't see anything about marking of the hooks themselves, though.
In looking at several hook manufacturers' websites, and even some of the OSHA information, I don't see references to any other documents for hooks, so there may simply not be any other standard for them.
