Bolt Size Help

[nwut05]

Maybe I missed it along the way. So what was the point of this exercise? Are you planning to bolt something to this assembly? Surely it wasn't just to plug a couple of open holes.

You missed part of why I wanted to find the correct bolt, and I have future plans to attach to those bolts, which I did not exactly specify in the post. My challenge and the first thing I had to do was make sure I had the correct bolts for the holes. Those holes are blond holes in the front of the transmission near the hydraulic shuttle and I did not want to be messing around too much without knowing for sure. I had tried some bolts I had and I had also contacted Kubota by email first then a recent visit, Neither one produced the correct bolt result and after trial and error and a few misguided post derailments It became a mission to find the correct bolts for the holes. One of the members here came through for me and really helped by being able to try a tap they were able to borrow and help me confirm the correct size. I had tried several bolts and the threads just didn't seem right. After I got another correct opinion, ( thank you KWENTLING) of the threads I purchased a tap and cleaned the holes and I already had some of the 16mm 1.5 threads and they are what works like a champ. In summary I reached out for help on the forum and I ended up getting the answer I needed and a lot of opinions along the way.

So that's why it too so long to figure out what bolts belonged in them. Blonds can be so hard to understand.

Rule of thumb: Cast iron and aluminum will always have coarse threads, whether SAE or metric.

Unless it is a Perkins engine, then almost if not all bolts are fine thread.

Later model Perks use 1.5mm (coarse) thread pitch.

Hello, I am trying to find the correct size bolts to fit my M6060 I am attaching a picture I found showing the bolts holes I am looking for. I have tries several sizes both metric and SAE but to no avail. And I have looked at the diagrams at Messicks and they are not shown. Anybody Know what size these are metric standard fine thread pitch etc. I need bolts to fit up in the two holes in front of this bracket someone else built in the picture. Thanks

We have Tractor Supply stores here. They have a plate with all different size bolt patterns. You can try until you find the corret one.
If that's not availiable, go to a hardware store and try the different size nits until you find the correct one.

He already found the correct size bolt...

But in this case, I think it would be a tad difficult to take the transmission casting of a 60hp utility tractor to the aisle of a tractor supply store...lol

Yea, I didn't realize there were already replies. Had I looked back........

It just occurred to me that the next time I run into identifying an over-sprayed mystery thread, I'll put a little Zip Strip in it the night before. (paint remover gel)

An assortment of smaller bolts can sometimes be used like a thread pitch gauge. Slip one into the hole and feel the threads drop into place, or almost, or not.
