5/8 Grade 8 Bolts... Where To Buy Them?
 

My GX150 has the Gen 3 spindles which are doing well so far. The only problem is I just upgraded to 20x7x8 tires and there is barely enough room for the axle nut to stay on because the hubs are wide. I am looking to grind off the original 5/8 bolt, drill all the way through and attach a much longer grade 8 bolt. Only problem is that I can only find 5/8" grade 8 bolts in 6 inches or less and I need it to run through the spindle, like the BD spindles. Where can I find a bolt longer than the 6"?

bought my 7-1/2" ones at Lowes- Fastenal(sp?) is another good place

Tractor Supply may have them, if you have one near you.

YAY!!! Went to Tractor Supply and they have a HUGE selection of Grade 8 bolts. I have one spindle pretty much completed. I was able to grind off the bolt and smooth out the old bolt head and drill right through it all the way through the spindle. I figure there is no possible way that is going to break. I still have to weld the new bolt on the back side of the spindle but it is very solid as it is. Need to find a friend with a welder. :)
