On engine hoists. Mine is one of those folding leg ones. The bolts that hold it together are Chinese metric 3.8 grade. In SAE, that's grade 3, pretty soft. One of the problem in using nylon slings is that the loops thick enough that they build up on the hook. Then they can slide off. It's good practice to use a shackle to tie them together. Ideally , put the shackle on the hook. Being a hobbyist, my machine tools are light bench tops, just a 1000# or so.
