Just bite the bullet and realize you are going to have to drill and tap new holes.

Use the plate the screws are in as a drilling guide. You need to determine the size of the old screws by getting one out if you can. Probably 8/32 or 10/32 or 10/24, or pick a size

You need the right size tap drill plus the tap. A bottoming tap probably would be best to reach the bottom of the hole which a tapered tap can't do. both would be best, unless the hole is deep enough for the taper tap, which is easier to use.

Your local machine shop will likely do it for you.

WD40 = Water Displacement formula # 40...

Can't figure why anyone uses a water displacement product for rust penetration... :what:

I bought a Gibralter CFS few weeks ago off craigslist for heating my garage. It had broken glass that cut the firebox draft down so I had to replace it. I wanted steady heat, tired off wood smoke etc, and after trolling this site a Gibraltar was to be my next addition to the garage. Mind you I’m mechanically inclined so wasn’t scared to tackle the glass job. It can be done and here’s how I did it to keep the snapping of screws to a minimum.

Start with a hot to touch door, take it off a hot stove. Soak all the screws with rust penetrating spray, I happened to a have a can of Popular Mechanics spray so that’s what I used. All but two screws backed right out after soaking 10-15 minutes. The two bottom center ones where in there rusted solid from fly ash laying in there, and they snapped off. Yes drill them out. Center punch close to middle off screw as posible. Drill with a 1/16 bit , or what ever fits the easy out your going to use. Must drill all the way to the bottom of the snapped off screw. They wouldn’t budge until I put a hole all the way through the screw. This allows the penitrating spray to get to the problem at the bottom of the hole. You will know when your there either buy deapth of drillbit or when you hit the very hard cast iron. Stop drilling, start soaking and heating up the door again. I set it on top my burning stove to heat it up and kept soaking with spray. I used a reverse twist easy out and was able to get both screws out and save the threads in the door. Yes this was a 2 hour job but All is well now, just nuther day at the office. Good luck!
