AlanM Posted February 15, 2017 Share Posted February 15, 2017 Does anyone know where I can get new screws like those used to hold door handles in place in GM products of the 1930s? I know Cadillac and Chevrolet used them and I suspect others did also. They are 1/4 - 28 x 5/8". They have domed heads that are 1/2" across the flats and are about 1/16" at the edge. Restoration Specialties had them in their catalog a few years ago but no longer stock them. Thank you in advance for any help. Link to comment Share on other sites More sharing options...

Spinneyhill Posted February 15, 2017 Share Posted February 15, 2017 If you are replacing that, it is repairable. Clean it up with a chelating agent or electrolysis and zinc plate it yourself. I have done a number of mine that way. There is plenty of information on zinc plating on the www, as well as electrolytic rust removal and some on chelating agents (e.g. molasses, citric acid, Evapo-Rust).

Curti Posted February 15, 2017 Share Posted February 15, 2017 I would say that bolt is not available other than a person that sells parts for the car you are working on. If that was 34-36 Auburn, I could help you out. If I were you I would cut the head down on a regular bolt then find a piece of tubing the size of the shoulder and the od of the bolt. You can solder or JB weld it on . Then take it to your local chrome plater. 1 Link to comment Share on other sites More sharing options...

edinmass Posted February 15, 2017 Share Posted February 15, 2017 Looks like 31 Cadillac door hardware to me. I have never seen them anywhere, we made them out of stainless, and buffed them up. Link to comment Share on other sites More sharing options...
AlanM Posted February 16, 2017 Author Share Posted February 16, 2017 John nailed it - The Filling Station carries them - $2.00 each plus .20 for the washers. They are a GM part - Chevy used them from '29 - '31 as did Cadillac in 1930 and 31 and probably other models as well. Thank you. Link to comment Share on other sites More sharing options...
