Super job on the fender David.....
Hi David
What size nuts, bolts, screw head is like saying you finally discoverd the exact shade of OD green used on January 14th 1940 on a cab 11...... whi si rigth and who is wrong.
Most cab 11 have had the nose removed many times by backyard mechanics and most of the fasteners have been changed.
You rounded 1/4 in. screw heads are not far from original.....but again "Waht is original..?" around here we those old type fasteners were refrred to as "stove bolts" ...common and cheap.....certainly would have met the production standards at the time.
I have included two picture of my truck at theearly stage of disassembly....notice the mix of 6 sided 1/4 bolts and round screw head.... the only difference is they mostly used washers to spread the stress on the sheet metal.
I personnaly believe that they were all originally assemble using the slightly rounded ..."domed"... 1/4 inch screw heads as usually found on the inside panels that were not subject to as many disassembly..... the domed head was a counter sunk 1/4 screw and used a counter sunk washer which we refer to as upholstery washer today. The domed head screws are still available today (even in SS) and so are the washers in chrome, plain steel and stainless.
But as I said yours look the part particulally when you are consistent and they are all the same.
If you have trouble getting the paint to stick to the screw head try the acidic bluing compound for rifles..... leaves the head dark blue/black and will help paint stick better.
I wish my truck was progressing as fast as yours.
