A screw.
How you would write a report on what holds two boards together better a nail or screw is the First you make notes on your topics of what your writing about . Then you get all the measurement of your screw and nail and you could write about the similarity's between a screw and a nail
A screw holds better than a nail.
a screw works better cues it has threads and a nail is just goes straight in the board. The nail is stronger but the screw holds tighter.
Even if you use a good supplier for your lumber, you might find that many of your deck boards are bowed. This can create gaps and sloppy look for your deck. To straighten out bowed deck boards, simply place the deck board against the others with the bowed side in and nail along the length until it is even with the other boards.
A screw holds wood together better than any nail because it resists being pulled out much better. A screw is also easier to remove without damage. However, screws are more expensive to make and take longer to put in, so nails are still used in a lot of timber work.
That would depend on the job.
To achieve a faultless finish on your new deck, be sure to stagger the joints when you install the deck boards. When nailing the deck boards on to the frame, be sure to leave even spacing between the boards. Most experts recommend 1/8 inch between two inch boards. To avoid measuring over and over, simply place a 16d nail between the boards to keep them in place and insure you have the right measurement.

Screws are better. A nail is basically a long smooth cylinder, whereas a screw has a thread cut into it which provides better grip.
A screw has an irregular shape, and has more to stop it from falling out. Also, A screw has an advantage because it's drilled in and the spirals makes it stick in faster and doesn't take long as a nail to hammer it.So, it takes a few seconds to screw the screw in.
ones called a nail the others called a screw. Also you hammer in a nail but screw in a screw. Hope this answer helps. :)
