Screws with Damaged Head!
Hi,
Does anyone know how to remove a screw with a damaged head?
Does using a hex key with Liquid Thread help?
Thanks

Yep a couple of methods.
1. Use the tool linked to from sears.
2. Cut a slot into the head and use a slotted (flat head) screwdriver to get it out.
3. Drill out the head of the screw Then grab the shank with pliers and unscrew it out.
These are all good solutions depending on where the screw is stuck.

welllllllll.................you do get NEW screws then.......lol
use that tool i told you about...any cheap tool house should have something like that....it works dam good...just remember slow is fast..lol
the dremel works but watch what your cutting near, as it will mark up the surrounding area as well

if you use a dremel to cut a slot, use the thinist cutting wheel. Sometimes smaller diameter is better, you can cut a deeper slot without cutting the car.
When I bought a good tools, my screws had less problems.

Thought I just share this experience today.
Bought a really mint condition carbon chassis TC, but then found 8 flat head screws which will not budge. A few were on the same side of the front and rear bulkhead and so the method of turning the bulkhead round to unscrew will not work, needed to at least remove until the one remaining screw is left.
Had previous experience before and I know if I were to put in more strength the hex heads will strip.
I do not wish to use a dremel for fear of damaging the carbon chassis. Last resort that I thought I'd use.
1) i used a lighter and heat up the screw head and aluminium bulkhead hoping to unbind the screw. after some tapping using a hammer on the driver on top of the screw head, a few came off.
2) left the chassis in the freezer overnight, one came off after a little bit more hammer work.
3) stick that part of the chassis in boiling water hoping that the expansion will unbind? a few more came off with some tapping again.
4) only 2 left which is on the same suspension mount. used an impact drill and drilled with the smallest drill bit I could find, anti clockwise. did not drill through the head but just left it on for 4-5 seconds, there was still a bit of head left for the hex driver to hang on to. somehow the impact of the drill turning anticlockwise managed to unbind the screw and it came out with no fuss.
Countersunk flat head screws love to bind to carbon chassis. Grease will help with the contact area between the screw and the chassis.
Excellant work done on my part if I may say so myself. The only cost was a few damaged screws.

sometimes you need a new hex head wrench. I surprised quite a few people with what a fresh expensive wrench can do. even nice MIP or hudy tools do wear out eventually. if the tip of the wrench is long enough you can dremel off the worn out section and basically have a new wrench. but always remember to throw away the stripped screws and get some new ones. no sense in make more trouble for yourself.

i hate the hex screws on top end cars. id rather phillips like on my old sprint 2. thats about all i miss, and flying/flipping over anything i wanted.

+1 for the previously mentioned tool. I've found it is the most consistent for removing stripped hex heads. You can find at Home Depot as well under a different brand name. Unless I am mounting a nitro motor, I also prefer to use purple locktite instead of blue. Harder to find but works fine for most RC screw applications.

SCREW REMOVAL
First, get a tool with a good tip, then get some coarse valve grinding paste from an auto parts shop and put a drop of the paste on the end of the tool and insert the tool into the screw head and wriggle it back and forth a bit to spread the abrasive paste. You should be able to undo most damaged phillips or allen head screws in this manor.......hope this helps
