I have a frigidare stackable dryer and the 3 screws in the back of the dryer drum keep working loose. When I tighten them it works great for about a load or two then they start getting loose again and you hear a "thumping". Why won't those screws stay tight? What can be done to get them to stay tight?

Are they machine screws which have threads?

What's the approximate diameter or do you know the screw size like #10 etc.

You would probably benefit by a threadlocker, like Loctite Green: Loctite Consumer Retail Products | Threadlockers (http://loctiteproducts.com/products/subcategory.asp%3fCatID=10&SubID=48), Locktite 290

If they are machine screws. I always have Locktite 222, a commercial product on hand.

Make sure you buy a product that does not require HEAT to remove.
