1937 Floorboard Screw Descripton Needed

[carlhungness]

       I am seeking knowledge of the screws that attach the floorboard transmission cover on my '37 LaSalle Coupe. I have none at present and seem to recall they had a fairly large round-head that was slotted? Am I correct? Suggestions for replacements needed.

[Steve Passmore]

You are correct. try 'Speciality Supplies'

[carlhungness]

Will do. Happy Thanksgiving, hope all is well with you and yours and appreciate your continuing advice.

Carl,
I have a replacement type that has a slotted/phillips head in stainless steel. They go under your carpet, but some people are fussy and need "original".  How many do you need? Yours for the shipping...

       Many thanks. I have not taken a count of how many are necessary but sure glad you found some with the rounded head. I personally don't care if they take slotted, phillips or square drive as they'll be under the carpet, which I hope I don't ever have to raise once installed. I'll count them and let you know.
Best,
Carl H

       I don't think they handle them but a local Fastenal store might. As suggested previously they are available in dual Phillips/slotted head but at the moment I do not have a source and will post when I do.

I think what you want is sometimes called a shutter screw.  A low profile, extra wide head to give good clamping force and be unobtrusive under the carpet. I bought mine from McMaster Carr in 18-8 stainless. I think 1/4-20 is the right thread for this, and you can choose your length. Also good for attaching the firewall insulation pad.

      I didn't think of McMaster-Carr, whom I do buy a lot from as I just imagined I'd have to buy 100 of them, and did not take the time to go through the catalog. I had not heard the term 'shutter' screw previously so have learned something. Thanks, I DO need more for the firewall pad.

[Steve Passmore]

The firewall pad screws have to be MUCH longer, and after fitting the surplus is merely cut with bolt croppers at the factory.

Steve,
You are correct again! I bought a few different sizes in boxes of 50-100. They're cheap enough to keep around for anything. 1/4-20 is a common size for other uses.
