What is name of a block’s attachment point?

To be just a bit more specific, that's a "stamped" "D" shackle. Here's a typical list of shackle types that might help you in the future.
One alternative would be to pass a bolt though the end of the block and make a Dyneema soft shackle. Very easy to do, no fids required. Depends on your load and how close it needs to be to the point of attachment, of course. I have made a few, and they work great. Here's a tutorial:
Becket is one of those terms that has multiple meanings, so it "might" refer to this shackle, to some. That would be confusing, in this case, because the becket more commonly refers to one of two things:
- The attachment point for a line, such as on a fiddle block or becket block.
- The loop in the end of the line that is used to attach the line to a fixed point.
This Garhauer block shows the shackle on one end and the becket on the other:
By the way, Garhauer would be a good place to look for a good price. SBO also sells them and it looks like they have good prices, though largely out of stock.
Joe is right that this is a stamped "D" shackle, but you definitely do not need to replace with a stamped shackle. Just get the dimensions and load tolerance right.
One word of caution is that, surprisingly, the size of the threaded ends can be an issue - not the threads themselves, but the bulk of those "fat" ends. More than once, I have purchased a shackle that seemed to meet my needs and dimensions, only to find that those fat ends would not squeeze through where I needed them to. Seems like a fringe issue and I wouldn't bring it up if it hadn't happened to me a couple of times.
Gotta love sailors, several words for everything. Ideally in a totally different context from normal humans.
I especially like "jack": lazy jacks are totally different from jack-tars, altgough they both might be lazy, plus jack lines, jack stays, etc. Floors are not what you stand on, although floorboards are. Ceilings are not above your head.
I'm liking your definition, a becket is a fixed attachment point suitable for a line, a swivel shackle provides motion more suitable for fixed attachment.

Keerect....... the becket will be opposite the shackle end(fixed or swivel) Very handy item that gives the block a number of options.
