I need to drill and tap a sheared off screw on a 50W Quadrant ring. This is the center screw.
Anybody know the thread pitch so I can get the correct tap?
I'm guessing 6-32?? or 8-32?
Don't know offhand, but I'd call Mystic or bring the other screws from the ring to a "real" hardware store to match up for your answer.
problem is....the two outer screws are a different size. this is the only screw of that size on the whole reel.
I've got an email into Mystic already.
I can not say for sure ,but 5-40 comes to mind .
A few pictures & part numbers would be handy, I might just have one of them screws, also with pictures we maybe able to work out how to remove the screw, it is hard to drill straight through a screw, good luck cheers don.
Mystic parts to the rescue. 5-40 is the answer
I'll use a #38 drill with a 5-40 tap and pray for the best.
The pic is where the screw is sheared off in the side plate.
:) 5-40 can be hard to find . but i did find them in Lowe`s hardware dept .
You can drill and tap all the way through the plate. I don't think it would hurt anything. It would be safer.
the original screw is all the way through the plate. drill and tap are on order from McMaster Carr
