The hex socket drive made cinching these down in a tight spot behind the motor mount a breeze. Knurled cup point bit into the shaft without slipping, and the alloy steel feels solid enough to trust for the long haul.

The knurled cup point grips the shaft firmly, so I didn’t need a locking washer on this setup. Alloy steel feels solid, and the hex socket drove in cleanly without stripping.
