Certainly not cheap. But a very useful fastener.
If I really wanted to use Grade 8 type materials, I believe I would source the correct Gr8 Socket Head Flat Head Screws and fab the sleeve to the desire length. Wall thickness of the sleeve could be controlled for the desired strength.
4130 solid bar or thick wall tubing would be a good material. Can't imagine that the price per piece wouldn't be cheaper.

If the results don't match the theory, change the theory.

Here I was under the impression that in a shear type of mount, a grade 5 is better, as a grade 8 is too brittle. Grade 8s are more for clamping pressure than shear. I think most stock suspension bolts are grade 5, are they not? Just stirring the pot. Were the old guys wrong in using a grade 5 in shear?l What I was told too, grade 5 for drive studs on axels more elastic, grade 8 has less shear strength, brittle. A guy had one of those tubular front ends with tubular lcas, while turning backing up slowly a 3/4” grade 8 bolt sheared off, car dropped to ground. Seams like a few had done the same so company made a double shear fix

I've seen some scary stuff from over there
