How do you screw a screw into a block wall?

If you have a studfinder, those are really helpful. If not, sometimes you can find them by knocking along the wall. The spot where the stud is will sound less hollow.

It is what it is. In ebonics it would read: It aint' a watermelon...

Ground screws are screws that have been ground into a fine paste in an industrial tumbling machine. They are extremely useful as a grout for tile. the term would apply to the green screw you find in...

of course it is the iron screw because it is made up of minerals that rust faster then metal

Usually with the tire iron/wheel wrench included with the jack. If that is missing, try a ratchet with a socket that fits. I've even used a screwdriver to twist it half-turn by half-turn.
