These bolts fit perfectly into my indexing fixture, and the black oxide finish hasn't shown any signs of wear after a week of heavy use. The threads are clean and engaged smoothly with no binding.

After going through two cheaper brands for my tooling fixtures, these M20 bolts threaded in smoothly with no binding and the black oxide finish hasn't flaked off like the others did. The 70mm length was exactly what I needed for a press assembly.

These M20 screws threaded perfectly into my jig fixture without any binding, and the black oxide finish looks like it'll hold up well. They feel substantially stronger than the standard hardware I was using before. Exactly what I needed for this tooling project.
