Where is a good source for new wheel nuts?
Technically you are not suppose to reuse the lock-nuts. I have heard people use them up to 3 times but the TM and McMaster-Carr indicate these are one time use lock-nuts. I will re-use two wheels worth of lock-nuts and see if there any problems. If there are, I will report back.
I think, but am not sure, that the bolts are 5/8"? (The wheel nuts on the M939 series truck, according to the TM, are 3/4" 16TPI Fine) The 5/8" are possible I guess but that may be for the Deuce and a half and/or older wheels, not sure which applies. My M939A2 uses the 3/4" nominal 16 TPI fine distorted lock nuts, flange style. I provided a link below for both sizes.
Thanks.
EDIT: The original purchase for the 5/8" nuts and die were too small. I went in a read the TMs that apply to the M939 and posted links to the TM sizes that apply. "locknut and threading die, 3/4" 16TPI fine." I was originally incorrect in my visual assessment of the stud size. That is what I get for not actually measuring. Nobodies fault but mine.
