Early guide fender light with wire connection on the bottom

Hopefully this is an easy one. Does anyone know the thread size and length of the screw that holds the electrical wire on the connection.

According to the 1941-54 parts book it is part number 2586, 6-32 by 1/2 inch round head machine screw.

6-32 -1/2 long is wrong at least with the 6/32. And I believe 1/2 might be a little too long. Maybe 8-32 I'm going to try to run a 8-32 tap through it . I will just use my hand on the bit to see if this is correct.

Just goes to show you can't believe everything in a Harley parts book. Checked a couple of light bases and they are 8-32. 3/8 long would be plenty.
