Out of about 70 bolts, these 8 (2 - M10X25 - each front and rear spring hangers) are the only carriage head and not yet ready to assume there is no good reason. Both the hangers and frame are punched square...

That's good thinking. It cost the manufacturer a dollar extra for each square hole, he did that for some good reason.

At over $250, I think I'll use a file. Not to mention the smallest is to large at a 1/2". (Seems to be a 13/32" square hole and the square neck on teh carriage bolt seems less than 3/8" - maybe 11/32" or 21/64".)
But thank you. If nothing else, while filing away I'll know I didn't overlook an easier answer.
