My COde 83 ones fit a 1-72, a 2-56 was way too big.
I used flatheads, drive up from the bottom (before installing the turnout, of course). I drive them in so the base of the screw was even with the top of the tie that has the hole in it. So nothing to cut off. The screw stick down below the turnout, but it goes in the hole drilled for the wire. The shiny brass dot now filling the hole? I painted it when I painted the rest of the rail.

Atlas makes a bus bar that fits in the groove of the tie next to the frog hole:

You would have to check with them if these come with screws. These bus bars come with the Atlas Snap Relay. (The screws are sold separately[!])

There was some discussion about tapping Atlas frogs here:

Also, Electrofrog is a Peco trade name for their power-routing turnout. I don't think Atlas has a name for their pot-metal frogs.
Good Luck, Ed
I only clicked once, but the reply appeared twice? See below:
Capt.Brigg The Atlas code 100, #6 Electrafrog has two ears with predrilled holes. Since I can't solder directly to the frog metal, I am threading the hole and putting a screw into the hole to solder onto. However the smallest screw I can use is a #2-56. Anything smaller drops into the hole and does not thread. However my #2-56 screws have a large slotted head that protrudes below the plastic ties and the shaft sticks up above the frog. I can cut the shaft off but I can't remove the head. What kind of screw is recommended for this hole in the Atlas Electrafrog frog? Thanks for any suggestions. Capt.

On mine a 1-72 tap fit, and 1-72 brass screws thread in.
