I am trying to remove a one piece base from a MDL 700.The allen screw is not rounded out yet but is oversized.Any suggestions what to try?I think I might be good for one more attempt with a bigger wrench before the allen rounds right out.The screws are locktite sealed.The other screws came but not easy,I tapped one wrench in while breaking the seal,the other flexed the wrench to where I thought for sure it would fail before the locktite gave.
Input anybody
thanks RB
 
pound a torx bit into the hex head. before you do it warm the screw up so it is hot to touch, to soften the lock tite
 
Another idea is to apply a soldering iron to the screw to get it warm.
Maybe a light tap on the screwdriver to help it break free.
Hope this helps

Before trying the above, use a flat punch on the allen screw and tap the flared metal back into the hole. I then vote for the torx driver, they're tapered so you should be able to pound one in for a tight fit.
 
Princess Auto has a minature impact driver for $10. It was on sale a few weeks ago for $5. Works great for screws like this. Uses standard 1/4 inch screwdriver bits. Much smaller than the usual impact drivers.
I had one Locktited scope mount screw that I couldn't get out. Heated it, broke a bit on it, nothing worked. A tap with a hammer on the impact driver and out it came.

If you need to drill, allen head screws are easy, a ready made pilot hole.
Take a drill bit about the same size as the shaft of the screw. Use a grinding bit in a Dremel or a grinder and grind the end of the drill flat (or use a broken one). Then grind a left hand edge on the drill bit. Use a good drill bit to compare as you work - it's not too hard to do. It doesn't have to be perfect, you're only drilling about an 1/8 of an inch. Don't get it too hot or you'll loose the heat treating.
The flutes are wrong but they only carry the swarf away from the hole - who cares for the tiny hole you are drilling.
Chuck it in a drill in reverse and go at it. You'll probably find that the screw will wind out while you're drilling - the heat and the torque work well.
I've done this before and it's always worked for me.
 
Success.
I drill out the top of the alen screw and removed the base of the screw with a pair of pliers.Thanks Guys for all the tips.RB
