Seized-up screws

[Newburnerwisconsin]

I have two 1/4-20 screws that are seized-up in my stove. How can I get them out without doing any damage to the castings or stones? I have already tried swearing and cussing.....thanks

Maybe a little penetrating oil. Just don't get it all over the place!

PB Blaster helps. Let it penetrate for several hours. Some times tapping on the head of the bolt will loosen it up a bit. Also try "rocking" it by very slightly tightening then loosening, then tighten, then loosen...

PB Blaster is good. But if it does not budge them I fall back on the hot wrench. Heat (propane, mapp torch) applied directly to the screw will expand both it and the surrounding threads, but the threads being a larger diameter will expand more allowing the screw to back out. It has never failed me.

All the above combined with patience.

Seafoam deep creep is my go to! Got my rear sway bar off last week and everything was seized!

Left handed drill bits if they break.

How long do you put the torch on the screw? Thanks for the info.

Door frame screw? One of mine broke last year. It was pretty easy to drill and tap. If it is one of those, they go through the inside and you may be able to get the various products on the inside end of the screw too.

I worked in Aviation for 35 years and we always used "screw extractors" or sometimes called "easy outs". Drill the heads and these have reverse threads that grip the screw and will twist them out.

newb,... heat it up with what you have (propane or mapp or....) then cool it off using liquid wrench (or what you have).......i do this 3 times on brake bleeders and have not broken 1 since i started doing this. i think the expansion and contraction losens things while pulling in the penetrating oil and
allows removal.......good luck.......rn

Thanks everyone for your replies! I got bot screws out with easy-outs! Learned something new today. Thanks so much to all of you!
