Call it old age or what ever, but I cannot remember the name for the type of Nut that has the toothed lock washer as part of it...

Need to get some and for the life of me I cannot remember what they are called...

There was a discussion here about them a while back but have been unable to find it in the forums...

Thanks in advance...

I think your describing SEMS fasteners or KEPS nuts. McMaster-Carr usually carries them.
