The thread pattern of the screw anchors it in the wood. You not only have to pull against frictio, but also against the natural strength of the fibre and wood itself.

Why is it easier to insert a screw into wood than to insert a nail?
A screw holds wood together better than a nail because the threading of a screw provides a horizontal grip on the wood. Nails are driven down into wood and have nothing but the pressure of the wood to keep them attached, which means it is easier to pull a nail straight out of a board than a screw.
Why is a nail pointed at the end?
The point is a "wedge" that separates the wood fibers as the nail enters, making it easier to drive into the wood without tearing the wood as a flat tipped nail would.
What will hold two boards together better - a nail or a screw?
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.
Why does a screw work better for wood?
Screws are a more secure fastening than nails because the only barrier to removing a nail is the friction of the sides of the nail against the wood, so it can be pulled loose by a simple torsion force. A screw, however, has threads, so a torsion force cannot remove a screw without destroying part of the wood in the process.
How can you tell if its a wood screw?
A wood screw will have a courser type thread and will have a sharper point.

Why does Oak threshold makes creaking sound when stepped on?
Very likely not the wood per se. Most likely the wood moving slightly on the fastener, nail, screw or other fastener device. If you can get at it pull the nail, replace it with a screw or coat a new nail and fill the hole with construction adhesive and reinsert.
To fix 2 pieces of wood a screw is better than a nail why?
because with a screw you have much more area gripping the wood and cannot under normal circumstances pull it out without shredding the wood where a nail has much less area in contact with the wood and being held in by friction only can be simply pulled out without tearing or shredding the wood.
Is nail a screw?
no. to insert a nail into say... a piece of wood, youd use a hammmer. to insert a screw into a piece of wood, youd a screwdriver, wrench, etc.
What is the force that holds a nail or screw in wood?
Friction
A hammer is used to pull a nail from a piece of wood How could the hammer be modified to make the task easier?
Make The Handle Longer
Can you hammer a screw?
It is not a good practice, but people do it. Some will tap a screw with a hammer to start a hole. Others will drive it all the way in. That is bad for the screw and the wood.Hammering a screw is counter-productive and will not have good results:When you hammer a nail into wood, the sides of the nail compress the wood. The compressed wood wants to expand pressing on the sides of the nail. The pressure keeps the nail in place preventing it from coming out of the wood.When you hammer a screw into wood, the threads of the screw "chew out" the wood pressing it downward, possibly compressing it in a downward direction, leaving little or no wood to hold the screw in place The compressed wood, wanting to expand may tend to expand upwards pushing the screw out.
How does a nail gun work?
you pull the trigger and the nail shoots out and into the wood.
What kind of simple machine are you using if you pull a nail out of wood?
You are using a lever when you pull a nail with a hammer or bar.
Why the lower end of a nail is made pointed?
It makes it easier to drive the nail into wood.
How a screw works easier?
Screws have things called threads and when you twist them into something, they get stuck inside. They work best with wood. Answer The thread on a screw allows it to PULL itself into say a piece of wood. No pressure is needed on the screw driver, just to turn it will be sufficient. The screw does all the work.
What hold two pieces of wood together better a screw or a nail?
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.
