1954 -- need diameter of screw head in door opening

[Peter R.]

Can someone measure the head diameter of the clutch head screws at the top rear of the door opening, as shown in the attached photo? The photo is from the "entombed Corvette." The holes in my car's body are empty--the screws are long missing. I'm trying to get replacement screws from Richard Fortier. He has 1/4"-20 x 3/4" clutch pan heads with 1/2" diameter heads that should work, but I'm trying to determine if they are correct. If it's possible to measure the diameter of the screw shank, that would be a big help, too, but not absolutely necessary. Thanks for the help.

Pete - Just removed one for measurement. The clutch head bolt is 1/4-20X3/4". The shank is fully threaded and the head is 1/2" in diameter. There is a lock washer and 1/4" thick nut on the inside.

Tim, Thank you so much. I couldn't hope for a better, more detailed answer than that. That's excellent, too, because Richard Fortier has screws exactly that size. If I can every help you, please don't hesitate to ask.

Thanks again,

Pete
