I'm looking for a largish screw lock to go in a jig mold I am working on. I see the two from Do-It, but what I am looking for is a little larger. Maybe a 0.200" diameter coil made with 0.030" wire. Simple right angle turn on the tag that goes in the head of the jig. They should have about 4 turns over a coil length of around 0.35-0.45 (plus or minus a little of course). I'm not looking for a custom run. I'm looking for a stock item. I'd make the mold fit the coil.
