Identifying 4F R10 Bolt 1

[Patrick1966]

Hi all!
I was wondering if anyone might be able to help me with identifying the 4F R10 bolt in the pictures.
I ideally would like to know the manufacturer but especially the tensile rating of it.
I have searched Google for it, but with not much luck.
Your help would be greatly appreciated!

Those are not standardized markings. Can you provide a vehicle make and some dimensions so we can at least identify which standard the bolt falls under? ISO, JIS, DIN, or SAE.

It will be a class 8.8 or 10.9 as no other strength grades are used for hex cap screws on modern vehicles.

Those 10mm head sized bolts are all over my John Deere commercial mowers.
