Im being a bit ocd but i want to sort it.

I had to drill a airbox screw head off as i couldent remove it.

So the airbox lid is held on with 3 screws and the other bit is just the screw shaft stuck in the lower part of the aliminium airbox.

Ive tried to get mole grips on it, will not grip at all, tried to spray tons of wd40 and get the pliers on it, again wont shift it.

So theres a screw shaft stuck in the metallic lower part of the airbox. Its too thin to drill any screw extractors in, any other ideas?

I had a similar problem with a few screws. And ended up buying a pair of pliers that are designed for these kinds of things. I couldn’t believe they work but they were great. https://www.amazon.co.uk/dp/B00NBSVYOY/ref=cm_sw_r...

File it flat on either side so the molegrips have something flat to grip.

Try giving top of the protruding section of the old screw a few sharp taps with a hammer in order to fracture the corrosion that has formed between the steel screw and aluminium box. Then a bit more WD40 or something and back to the grips or pliers trying to work it back and forward small amounts until you can remove it fully.
Obviously only you can decide how hard you dare hit the screw so as not to damage the box but you don't need a big hammer just sharp shocks.

ETA. You could also try tapping the box with the hammer around where the screw is if this is accessible.

HTH,
Carl.

Side Cutters

Like this but you are cutting into the Head or Shaft. Better grip than Pliers/Mole Grips

Have removed lots of damaged Screws from Electronics and Masonry this way.
