Screws

[spiff84(2)]

Hi

i am having big trouble removing tight, worn screws from my 2nd (or more) hand Astute (Philips head screws) and Losi XXCR (Alan key screws), i need to get the little pests out to replace worn parts. I did a search and there are no topics on how to remove battered screws, accept for a mention of drilling them out. Any ideas or tips guys? and how do you drill a screw out? I don't think there is any glue or threadlock holding them, but i could be wrong.

Thanks

Take your dremal tool with a cut off wheel on it and cut a slot in the top of the screw. Then you can use a plain old flat blade screwdriver to remove the bad screw. Of course the standard warnings of wear eye protection apply here.

For countersunk screws you have to buy a countersink cutter for your drill of the same angle as the screws. Then just drill the screw with it until the head is removed. The part it was screwed to will now have the remaining part of the screw left in. Just take your pliers and twist it out.

Ask at your hardware shop, they may have tools that help back-out stripped heads. They look like "reverse wood/self-tapping threads on a t-bar handle", you drill a small pilot hole co-axial into the target screw and then tap this handle in (turning anti-CW). Eventually the original screw will catch on the t-bar's thread and it will budge. Not sure if they make 'em small enough for 3mm though.

They dont im afraid as Ive been after a set as im always stripping the heads on my Maxx screws - Ive asked around and apparently to make it small enough to fit in the screw it would be too weak too take the strain

Yeah, have seen them used on larger bolts before (1:1 car), Pity.

In which case I'd go replace all your screws with high-tensile ones - Sounds like the screw metal on yours are a bit too soft. I'd stay clear of anything made of aluminium and titanium...

But that might add 1 or 2 grams to the overall weight which would be a disaster as the power to weight ratio would go through the floor! []
