Nut, Hex Thin Chamfered M6

I swapped these onto a tight engine bay fastener where a standard nut would have stuck out too far. The chamfered edges let them thread on smoothly without catching. They lock down securely with less height than I expected.

The lower profile sits almost flush on my assembly, which freed up just enough thread for the washer. Chamfered edges made hand-starting them a breeze, and they snugged down tight without any wobble. Exactly what I needed for a compact locking job.

Used these as lock nuts on my spindle assembly and the low profile sits flush enough that I didn't have to re-machine anything. The chamfered edges also made seating them with a wrench feel much cleaner than a standard hex nut.
