I need an original nut for an L-iron. I ordered a "special nut" from a vendor, but it's just a regular nut.
I meant to put this in the classifieds.
To replace the nut you show, a 2h nut from Fastenal would be close. Dave in Bellingham,WA
A 7/16-14 2H "heavy hex" nut is still only 0.750" across the flats whereas the L-iron nuts I have measure 0.780". Doesn't sound like much, but you can see the difference. New ones are also a lot more civilized looking than the originals.
May not be the same, but you are welcome to these two if you want - let me know - I also sent an email to your regular email address.
