Stubborn Steel Screws

Stubborn Steel Screws
I have some stubborn steel screws threaded into aluminum (Losi Type-R) and i can't get them out, i broke 3 integy 1/16 wrench tips trying. I tried the "shock" method (put the flat of a screwdriver and tap it w/ a hammer to jar it a little) and that didn't work. Scared to use heat for fear of warping or melting something.
My though was get a soldering iron good and hot apply it to the base of the aluminum strut where the screw is threaded and then try to get it off before it cools. Thoughts?

If you used thread lock the only way i can see possible is if you remove the screw after applying heat with a soldering iron to the screw head,
if you didn't apply thread lock, is the screw head stripped?
if so, do the dremel method, if it isn't, well, i don't know what to tell you, i've used a full set of integy's for 4 year now, and no heads have broken.

You could try drilling the screw out. You need a very sharp and tough drill bit (I find cobalt coated bits to be very good) which is a bit smaller than the diameter of the screw. Drill out the centre, a fair way down, and then you need a reverse tap. This taps a thread into the hole you have just drilled in the screw, and as it is reversed it means that you are turning it anti-clockwise. Hence when the force required to cut the thread is greater than that required to back the screw out, it will simply undo and you can then replace it.

The screws are in w/ threadlock, they are not stripped. I'll try the soldering iron trick first (i have a 1,000w iron) and then i'll slot them I'd like to save the chassis.

Apply heat, then quickly try to undo the screws but using the allen/screw driver at a slight angle. it may just have enough bite to get the screw out

I personally never use thread lock and have not had an issue with the screws backing out at all.

I have more problems with wearing out wheel nuts. I guess I am just fortunate or have just the right arm torque to keep them in the car.

For a flat head screw that attaches a metal part to a countersunk hole in a graphite chassis, prep the countersunk hole in the graphite (not the threaded hole in the metal) with a little CA first. (One drop of thin CA spread around with a Q-tip works well.) Let the CA dry fully, then tighten your screw. Don't use a lot of torque; just tighten until you feel the screw head "squeak" into place. The screw won't back out, yet you can remove it when you want. The CA needs to be renewed when you don't feel that "squeak".

Use the heat. No need to do anything else.. The next thing i'd try if that failed is a left handed drill bit after heating.. Should back it right out
