Any leads on a screw

[Kenneth T.]

I have a '71 LS5 with the CEC system. I need the screw that holds the bracket to the QJet carb. I believe the bracket # is 7042654.

I did not list it on the difficult to get parts, but it truly is. Thanks.

The problem is the head shape - sort of a cross between an oval head and a fillister head. The thread pitch is nothing fancy.

They used the same screw on other GM vehicles. I purchased a carb at Carlisle a few years ago just to get that screw, the solenoid and the bracket. It was not a Corvette carb but the parts are going onto a 72 Corvette.

Yes Ken, That is definitely an uncommon screw. I have recently done business with Phil at Custom rebuilt carbs and he seems to be good guy.
I would contact him if you can and mention the NCRS. He may be able to help you.

Patrick, Michael,

Thanks for the reply and lead. I will check with Phil. I can get fillister head screws in black and cheese heads but I guess cruz'n the junk yards or buying and old GM car just for the "screw" may be my only option

How about some one posting nice pic of the special screw.
By the way. A cross between an oval head and a fillister head could be a pan head screw???
What is the exact size of the screw as I may have it. JD

There are a few loose screws wandering around in your shop ChePhart

Dick,

Linky no worky.
It doesn't show a specific screw.

The original has a taper on the bottom to "center" the bracket. That's why I say it's a cross between the oval and filister head.

If I get a chance I'll post pics of my NOS one tomorrow.

The external portion of the screw looks like a standard slotted fillister head screw. How would using a standard slotted fillister head screw be discernible from the original screw once installed?

Thanks everyone. Joe, that will be my back up plan.

Ken:
What is the thread size of the screw you need? I have a box full of old carb screws and maybe one of them is what you need.

Thank you Jeff, I will check later and let you know as I am not sure.
I checked. I have a 10/32 screw in there now and it is a little loose in the bore. I don't dare tighten it.
But as you know, that could be "special" too!
