[TowerTalk] Looking for 5/8-24 nuts

[Huff David J]

I am looking for a mounting nut to hold N or PL connectors, but thicker than normal. NOT PANEL OR JAM NUTS.  This would need to be 5/8-24 UNEF, but thicker than the standard jam nuts or panel nuts.  Those seem to crack too often.
An ideas who would have small quantities available?

Thanks,
David J. Huff
