The axle U bolt nuts on my 836 were pretty eroded and I have been searching for a replacement. I finally found these 5/8″-11 Heavy Hex Nuts (Structural) – Plain and they seem to be just about a perfect replacement. Correct height and thickness.
They may be the same for the front bolts, I haven’t checked.
They came from Trinity Fasteners in Grand Prairie, Texas. 25 in a bag. Enough for double nuts on one axle and a few spares.
I have no interest here other than info.
