I asked about these chain hooks in a previous thread, now hoping a dedicated thread will unearth the answer. They come off of a Peck & Hale shock mitigation tiedown set. Going through the Peck & Hale website doesn't give me a name for this type of hook, or why it is designed this way. Anybody know the purpose of this design?

The hook looks like it's designed to go into a Deck Socket and engage a cross bar for cargo tie-down on a ship, etc. I recall seeing hooks similar for use in old body shops for frame straightening. Since this company makes specialty items there is a good chance there is no name for the hook and it's design. Just a P/N in one of their replacement parts catalogs.

That seems reasonable. Designed for a single purpose, a non-moving bar slightly smaller than the throat of the hook. Thanks Mike.
Maybe we get naming rights... How about something fancy like Shaft Gripping Tiedown Hook.

Nah, that is a Cankles slow motion neck hook.
More surface area to prevent a quick and easy passing.

I think it may be a deck gripe, for lashing stuff down on the deck of a ship or boat.

Similar. I think the ones they used on cloverleaf deck fittings had button heads with pelican hooks for tightening. The design in the OP's pic is a great idea as it uses two of the same part, costs a bit less to produce.

A friend of mine who is a oceangoing tug engineer stopped by yesterday... I was confident that he would know. Nope. Never seen the like. I'm going with the "crossbar tiedown hook", specifically made for encircling the right size steel bar inset into a deck or wall. Along with the funky hooks, each set contains 4 of these Hammerlock type connecting links. I've owned a lot of rigging that came with them already installed, but I've not installed one myself, probably because I haven't seen the need. They are beastly expensive, and are commonly used at a master link to attach legs for a lifting device, and I've seen them used to attach hooks to chain too. The hardened steel pin has a recess in the middle, and when assembled it is tapped through the split ring spacer, which springs down to the recess diameter preventing the pin from falling out. One end of the pin is slightly tapered. I almost always use this type of hook (not the grab/slip, but the manner of attaching to the chain): This kind of hook could benefit from the spendy links, but I am ignorant of the pros/cons that would justify a $30 connecting link to attach a $10 hook: Anyone know the reason that these are commonly used to attach hooks to chains? I can see why they get used on the master link end... I'm curious about the hook end.

I like the look of those hooks. It would be almost impossible to not get a good hook up because of that extra articulation in the link.
