Stripped hex jaw screw

>Dan - I would drill it out until the drill hits the top of the threads. You basically want to destroy the conical head without drilling into the jaw body. If that doesn't work you can use a grinding stone on a dremel. Slower, but more precise.

If you want you can just come by today or tomorrow and I'll drill it for you. Saturday - just come over anytime. If Sunday - let me know an approximate time.

>A screw extractor or "easy out" is the way to go Dan. Use one of the square ones that have a left hand twist. My stronghold chuck has allen head screws (5mm) that fasten the jaws in place and I had a similar experience, but the screw extractor saved the day. Not sure if the Nova is the same or not. I have a set of Snap On screw extractors (square variety) and the smallest one in the set did the job. Product number on the extractor is SR4, hope this helps out. Good luck.

I have had good luck grinding the edge of my hex wrench and then tapping on the top to seat it really well in the hex. A freshly ground end is truer(if that's a word) and sharper and willoften grab when an older one won't. If I think it's going to be a serious problem I I scratch it reall good with a file and then epoxy the allen wrench in the hole with JB weld.

I don't even try the first two on screw that are rusted or corroded, it's a waste of time but something like chuck the screws are usually just stuck and will come loose with a little force.

If that fails an easy out is the best choice.

SCREW EXTRACTOR YES !!

>If all else fails and you can not extract the screw or you ruined the piece on the chuck, you can buy a set of those slides (?) from Nova. I was on the website and they have them listed as an accessory. They seem to be advocating leaving them attached to the jaws and changing them along with the jaws as a "quick change" technique. I'm not sure about that. I guess with a little practice that would be faster, Maybe?

Incidentally, I bought an extra set of jaw screws (at Woodcraft). I was fearful I would drop one and not be able to find it. Seems odd to me that you buy extra jaws at enormous prices and they don't give you another set of screws. Clearly would be a good idea to have them on had in case the screws start to show wear.

Re: A tip to help prevent stripped screws.

>Note: be sure and do this before you strip out the screw head.

Take one appropriate sized allen wrench and cut off the bent end so that it can be used as a punch. Lay the chuck flat, put some support under the edges, put your new allen wrench punch in the stubborn screw and whack it sharply with a hammer. This will serve to break the torque bond between the threads and facilitate removal.

This is an old motorcycle mechanic's trick. An impact screwdriver with an allen wrench tip is also effective.

Finally, always make sure that your screws are lubricated with a light-weight oil before you install them. As long as they are tight, they won't come loose on their own, but they will be much easier to remove.
