Hi

Anyone who knows the thread size of EOS switch bolts on Bally -35 games (Vector). If there is any common size.

I've gotten some 6-32 ones. But they appear to be too big.

I believe they are a #4

I believe the screws are 5-48 or 5-40.

My problem is, that I measured the (too short) one installed at 3 mm dead. And #4 is defined at 2.84 mm and #5 at 3.18 mm. Where does that leave me.

Of course, it might be a metric 3 mm one used. And I might just replace my another 3 mm. It has a fine grip.

I put a thread gauge on one and it is a #5-40 x 0.590" long. Length measured from bottom of head to end of threads. Overall length is 0.695".
It measures 3.09mm dia.

This is from a linear style flipper from my silverball mania. Not sure if the early flipper used the same switch so the length may vary if that is what you have. Either way, im sure the thread size will be the same.

Silverball Mania was made before those crappy Linear flippers appeared on the scene.

Someone probably swapped them at some point before you bought it.

Please switch them back and make your SBM play without all that slop!

#5-40 it is.

I was at the hardware store today and tried a #4-40. The thread pitch was perfect, but the screw was too small and fit loose.

Vid I was thinking SBM was way earlier and should have the other flippers. Im doing a pf swap on it now (gotta get back on that) and will swap in some early flips. I believe I have a spare set around here.
Now that I think of it someone did mess with those flippers. One was wires wrong and would stick open after releasing the button.

Yeah, somebody stole the good flippers and stuck in the bad ones.

At least it's an easy swap, and I'm sure you were going to rebuild the flips anyway....
