The AN363 series is the best and preferred choice over the AN365 for applications forward of the firewall. The AN365 nylon inserts become soft and this product holds.

The style of the AN363 nut is a little different than the nut in the picture. The AN363 has serrations in the locking portion (not a solid collar like the illustration).

As listed, as expected. However the picture is not representative of the AN363-720 nut - the nut is a slotted collar stop nut.
