Well, I don't really know. I got the pair used on CL, it was in rough shape. But the orbitals seemed to be ok. I removed lenses and rubbers to send off the the x man. Had the bridge tuned up and had it refinished in x metal. Got them back and now the screw doesn't seem long enough. The gap is huge too!Did it work before, or did you get it this way? What changed?
As far as a screw driver I am using a ratcheting driver I got from lowes that has a t6 bit. I have used it for 2 years now with no issue at all. It turns the screw fine, no slipping or anything, it just seems like the screw is to short, my guess is because the gap is to big. Can it be bent closer?
