Dose anyone know where I can get some Stainless Torx screws for my ZT 566. I'm looking to replace the scale and clip screws. Trying to match the threads has been a problem at my local hardware stores. Any help would be appreciated.
 
The clips screws are 2-56, most hardware stores will have some machine screws that fit the bill. You might have to cut them to length though...also chances are they won't be button head screws, or stainless lol.

Go on knife kits, jantz knife supply, USA knifemaker, Texas knife, etc, and I'm sure you'll be able to find some that fit your specs. Sorry I can't help with the pivot.
 
The main body screws are 4-40. The pivot screw appears to be metric, M3.5. I'll double check on that when I go to Ace this afternoon.

Can't find M3.5 at ace or home depot.

I realize this should be a standard american screw and not metric, but I'm stumped.
The outer diameter is about .135 inches, which indicates a #6 screw. The threads are much finer than even a 6-40 though, which leads me to believe its an M3.5 of some sort.

Most likely its just a size I'm unfamiliar with. Sorry I couldn't be of more help. You could always just remove the coating on the stock screws as a last resort.

Thanks Steve, I think I will just remove the coating.
 
Order a new set of screws from ZT. They will ship them out for free.
 
I am fortunate enough to have a set of pitch gages to measure threads. You can use known screws as a poorman's pitch gage. I use this method at work when I don't have real pitch gages available.

I found an online pdf file that is a drill size chart. On the bottom, they have a tap hole size chart. The nice thing about it is that is has both english and metric listed in order of size. Makes it easier to figure out what metric sized are a similar size.
