Bolt with "10" on the head

I planned to loctite them anyway.

Yup, Loctite nearly everything. I never used to but it just solves so many problems before they happen.

It is probably a shortened version of the 10.9 metric designator. I agree, forget the dealers, probably pay 2 prices for one. Also ditto the thread pitch, it may be different than a standard off the shelf; but, you can be sure the tractor assembler is not using something that is uncommon in the bolt world. You should have a good supplier like Fastenal around. Take it with you and match up. Those places are very helpful and sell by the each. I have never bought bolts from and OEM assembled product. You can make some subtle improvements that way, such as head type, grade, and driver style. I always use grade 8 for items with dynamic loads no matter what the original was.

I imagine CAT sells metric bolts,,,
I bought some bolts from CAT when I built my landplane.

To say the least, the bolts are impressive. The height if the head is much greater than a regular bolt.
The bolt on the left is CAT,, the bolt on the right is TSC.

The price of the CAT bolts were VERY close to TSC pricing.

Also,, you get the cool "CAT" logo on the head,,
it will impress buyers when you go to sell the tractor,, they will think they are buying a CAT!! :laughing:

There are no concerns about grade when you buy a CAT bolt.

Its just a high tensile metric bolt, all the ten is there for is so you don't put any 2 cent metric bolt in there that will thread in. You see 8s all over motorcycles, where they count. Same thing you know to replace with a decent one not one made of playdoh

I buy specialty bolts from my local JD dealer often. They aren't any higher than the local farm store. And as CADplans said, the quality is much superior.

CAT bolts are the king of bolts. If I'm ever in need of a bolt with unquestionable character, I get a CAT bolt.

EDIT--let me add that I buy most bolts at JD like ovrsd does. They seem to be much better quality than comparable farm store bolts for not much more money.

I agree.

Take one out and go go auto parts store and see if they have a similar bolt by Volkswagen. The one's I got were identical to the one I brought in.

Fastenal will have any bolt (or can get it if not in stock) but I find my local Fastenal to be good quality but super high priced. They can measure and tell you the exact size and thread pitch needed though. I don't know that the bolts in most farm supply houses are high quality, most likely cheapest that they can find. I wouldn't use them for critical component fastening, get a quality bolt from a reputable manufacturer that can get you the mill certs (heat number from the ingot used, tensile tests on the as produced bolt, alloy components, etc) on the bolt if needed.

One of the more useful things I have is a complete metric tap and die set. Then, given any nut or bolt, I can determine the thread pitch, diameter, etc right on the spot. Then I can walk into a store knowing the bolt I want and not have to spend time jerking around and trying to measure threads and pitch.
