We did find the 2024 aluminum hex to be slightly undersized and work perfectly for us. It's significantly more expensive, but we didn't mind the extra strength it provided.

I spoke with 846 team members who also explicitly recommended Vexpro Hex stock over McMaster Carr. They said that the tolerances were off/not precise enough as well.
