how does this work?

[dbhill916]

Just a random technical question for the group. I had to drop an exhaust pipe (long story) and noticed the curious locking nuts used to keep them on the engine. Can anyone explain what the slot does and/or how it holds tight?

thanks,

That type of nut is called a double slotted locknut, Google has a lot info.

Thank you. The proper nomenclature was just what I needed.

It is a common Volkswagen exhaust nut. In fact when I needed one and it was going to take too long to order, I went to the local VW rebuilder and picked up a dozen, cheap compared to Rotax.
