how to unscrew or tighten old screws in the deck?
 
I just finish power washing my deck. I noticed that many screws are sticking out so I tried to screw them down with a screw gun. Some of them broke, and on some head got stripped. However, not single screw i was able to tight or unscrew without breaking or stripping:furious:. Could anyone tell me what can I do? Thanks :)

You could try using a screw extractor, such as GrabIt. It sounds like they used drywall screws which simply were not meant for exterior use and have rusted over the years.

Any old deck screws will become very hard to unscrew or screw in tighter. In most cases the head strips out or it snaps off. Best bet is if you can - unscrew them & use new screws

I have a 12x12 deck out back that I installed last year
Once the boards dry out & shrink I'm going to take it apart & move the boards closer together.

Drill them out
 
Drill the heads off the bad screws and sink new screws. You are wasting your time fighting the old ones, not worth the effort. Use Torx screws, stainless if you can afford it. Dorf Dude...

Why on earth would you want to do that?

ive never had much luck with those screw extrators that you chuck in your drill:no:

I'm having the same problem with some of the screws on my deck. But I only notice it when the snow shovel stops suddenly and I'm still moving forward :yes:. Is there a way to put the screws into the wood so they don't work their way out?

Could the rest of the screw work it's way up to the surface? Ouch!

Sometimes giving the head a good tap with a hammer before trying to back them out will help dislodge them. Doesn't work all the time but it helps considerably.

I've used the grabit extractor bits and they work like a charm every time on getting stripped out screws out.

An impact driver will go a long way to removing old deck screws without stripping the heads. Certainly beats a drill/driver every time.

Impact Driver
 
I totally agree with the impact driver. You could use the diamond paste Screw Doctor together and you should get good results. Impact drivers rule! Dorf Dude...
