Tap/thread sizes

I dont know your tractor but I would look into drilling out the hole and putting in wheel studs. that way the studs could be changed if damaged and the wheels would be easyer to put on....Larry

Pacman, I looked today for studs but no luck. Mine has a 3 inch HEAVY spacer between the hub and axle also.

I went to the fastner store here and bought a 27/64 drill bit and a 1/2" spiral tap that should solve the problem. I would like to find some grade 5 all-thread and make me at least two studs as it makes mounting the wheel spacer/wheel a lot easier.

thanks for all the replies.

tlbuser, I now have one of those laminated on my wall! thanks

I normally would not change std to metric but apparently the previous owner decided to do that with the left wheel and then used smaller longer bolts on the right side with washers/nuts on the back side. Not good. So , If I re-thread the right side back to metric and the left side is larger than M12 (5/8") then I would have std/metric rear wheel bolts. I just want to make both sides the same regardless.

thanks for the replies.

NICE CHART. Bummer that it doesnt show the metric fine threads. If it did yould notice the almost perfect crossover at 12mx1.25 and 1/2x20. The threads match. You can run the slightly larger 1/2" tap down the 12m hole following the original thread. Another almost perfect crossover upsize is 18mx2.5 to 3/4x10. Bummer that they dont show 18m on chart either. Its a standard, but less common metric size in coarse thread. These crossovers can be very useful to repair a damaged threaded hole.

M5x0.8 and 10-32 are a very close match too.

Yeah, good catch. On that one the metric is bigger. Unfortunately not bigger enuf to fix a stripped 10x32 hole. :( ... Still valuable for upgrade - or to fix in early stages of damage.

I have tack welded wheel stud heads in before. I would take a look at drilling out the threads and putting in a metric bolt from the back side and tack weld the head than use a lugnut to hold the wheel on. I dont like wheel bolts......Larry

Every wheel needs at least 2 studs to line it up as you put it on.

I agree with having studs. I am going to fill both rear tires with w/washer fluid and it helps to align when putting the wheel on. I also don't like to see just 2-3 threads on the backside of the hub.

Where can you buy STEEL bolts now days? Every where I look is Zinc and I don't like welding zinc. Maybe McMaster carr??
