If you look closely at the angle under the head, it is closer to a plow bolt.
Looking at picture two, I zoomed the picture to closely match one inch on the scale, then I measured the head size in picture three. You’ll see that the head size is closer to 5/8”.
However, MSC doesn’t carry plow bolts that small (1/4”-20) nor have I found any place on line that does.
I would post an ad in the” Truck Parts Wanted” forum. I’ve had very good luck getting what I need from fellow ‘bolters. Good Luck!
