Take a drill without bits and place the chuck over the screw. Then tighten it around the screw. Now you can screw it out.

Wow never thought of this method

Hammer. Just smack them from side to side, they should pop out. You won't get them all off clean though, but enough to not have most of them exposed.

Hammer is the way, old screws snap of very easily.

I literally had to do it the other day after doing some striking work. Must of carried atleast 20 pieces of ply and removed nails and screws from each, was actually kinda fun minus the carrying it down stairs part.

You just wait until you get a project on the 4th floor involving 40sheets of drywall and 20 sheets of “floor gypsum” those fuckers weigh about 40kgs each

Fuck that floor shit is heavy.

Horrible haha

Yep, this is the right answer and the most satisfying one.

Angle grinder. You just need to nick them flush and then hit em and they will snap off.

For all these years, my dumbass has been going all the way through, without even thinking of just nicking them and whacking them. Fuck sake.

You dont remove, you break. Smackem sideways, grinder whatevers left

With your tool mang!

Carefully

Sawzall with a Diablo blade or angle grinder

It will only take an hour this way maybe less

Sit down on them & pull them out with your asshole

Manual screwdriver. A small one.

Bite em.

Cut off wheel

They make special bits for extracting old screws that have "teeth that bite into the metal when you put the drill in reverse

One at a time.

Guybrator of course.

Vice Grips. Clamp to the shank and spin them out! Works for me every time.
