Corrosion and stuck screws- Suggestions?

[handi2]

I rarely work on big game gear but a Penn International that came in had a few screws that defied extraction.

A very experienced friend of mine offered some advice that proved to be correct.

One would naturally assume that corrosion was binding the threads to the casing but this was not the case.

It was a hard calcified layer between the square profile screw head and the casing was actually binding the screw in place.

His solution was to first dissolve this with hydrochloric acid.

I did not believe him till I drilled the heads out and found that the threads could be easily extracted by hand!

Quite amazing really.

That's a very common problem on neglected Penn International reels and Shimano Tiagra reels.

I may have to try that one.  I usually use all the other tricks, then drill the head (s) off, pry the sideplate off, and grab the screw with a vicegrip to back it out.  The sideplate screws can usually be backed out if the frame or posts once the plate has been removed.  I have only had 1 case of the frame getting damaged when trying to remove corroded screws here.  The stand screws are best left alone if they are badly corroded though since there isn't much metal to work with here.

Acatone and auto transmission fluid 50/50, will move most things, before screwing it heat with hot water, a few taps on the driver, tighten screw before undoing, be paitent, cheers don.

Hey all,

New member here. I've dug around the posts and tried some searches with various different words (stuck screws, Corrosion, frozen, etc). I know there must be a thread discussing the options when you come across frozen screws (salt wtaer corrosion) but I have not been able to find one. If anyone runs across an existing thread discussing it I'd love to get a link to it.

I've seen some discussion about acetone and mineral spirits but just slight mentions and no in depth discussion like you ususally have here.

Many Thanks!
