im using weaver bases on a slug gun and i cranked the screws tell they were tight i dont think i over tightened them just went until they stopped turning easily with the allen key i just want to know if it is possible to over tighten them and how hard you can crank them before that happens

Well, although I guess there is a torque rating for each screw, I do the same thing you do - tighten it until it doesn't turn easily - but not "over tighten."

But what does that mean? Well, to me, there is such thing as over tightening, and that's called "breaking." I have snapped screws before, and it's no fun thing because then you can't get them out!

My practical advice is to continue doing what you are doing, but just make sure that you use Blue Loctite before you start screwing.

Zachary is right and most importantly, as he said, "make sure that you use Blue Loctite before you start screwing."

Reading this post and 2nd guessing myself. I just had the local gunsmith install a new VXIII 3.5-10 x 40 on my Rem 700. I have used the dual dove tail rings as recommended by the posts on this forum. I did not have the tool to twist the ring bottoms to the bases. After getting to the range, I found I needed to move the scope forward about 1/4 - 3/8 of and inch. I have the torx screwdrivers. I loosened the ring screws, made my adjustments, including setting the cross hairs for my natural hold on the rifle. I snugged the screws up tightly with out exerting the pressure needed to strip the threads. I did not use any lock tite. Is this something I should go back and do? If so, can I loosen the front, put on the lock tite, retighten, and then do the rear so that I don't have to reset the scope?

I don't use Loctite on my ring screws. If you feel a need to use some, use the green formula Loctite and turn the firearm upside down and put a drop or two on the screw threads. The green formula is supposed to wick down the screw threads and then set up. The green is also the weakest bonding thread locker. When using thread locking agents it is a good idea to clean the holes and screws with Ronson or Zippo lighter fluid to remove any oil or grease.
