Head Allis

Determining hex head bolt grade?
I rebuilding my 1963 tractor, Allis Chalmers D17. I’ve taken part of the engine out of the frame, and have dismantled part of the frame. Some of the 5/8″ x 3″ bolts are moderately rusty on the threads. The head of the bolt is stamped with a square. There are no numbers, hash marks, or other kinds of marking on the head. It’s just a square. The other bolts on the tractor are grade 5. What grade are the bolts with a square? I’ve already looked online and can’t find a square marking for the grade of a hex bolt.
I couldn’t find anything with the information I have. I would say just throw a high grade bolt in there.
This must have been before all bolts went to a standard for grading? Either that or the square doesn’t mean anything and could be a company marking and the bolt is just a low grade.
