I need to replace some broken bolts on my tractor's front axle. They have a 10 on the head, not sure what that means. Any ideas?
Bolt with "10" on the head

Common to see metric bolts with numerical markings. What I pay more attention to is the grade of the bolt in hardness.
Curious why you have broken bolts?
You might want to visit with your dealer parts department concerning these bolts so you get the right grade.

Dealer went belly up a year after I bought the tractor.
There are 6 bolts, usually. Currently only 3. I guess some worked their way out? And others couldn't handle the strain.
There are no hardness markings that I can see.
Thanks.

The tractor is a Mahindra, made by Mitsubishi, so this is probably correct.

Not knowing specifically the bolt's purpose, I'll go out on a limb and recommend Grade 8. Might take one with you to the store so you get the correct size and thread pitch.

That was my plan.
It holds the "down angled part" that the front wheel attaches to, to the main axle.
