which one holds better screws or nails?

Screws-the threads on the screw have more "bite" into the objects you are holding together.  Nails can pull away or come out completely.

Either one will get the job done.  I would personally go with the cheaper solution

Use a nail file after cutting nails.

check for screws if you see none then just give a simple pull it will be held together with snap clips

I will answer your question with a Japanese proverb.\n\nThe nail that sticks up, is hammered down.

clamp and twist is much more effective.  :)

Depends on what you are mounting....but most likely because it is cheap and safe.\n\nIt is also often used to dehydrate specimens without collapsing their structure.

They each serve a useful purpose in their own way.  It is difficult to pick one over the other because their purposes are so different.  It woul ddepend greatly on the society and culture.  If  your work is driving, tram might be the most important one.  If you are an Inuit hunter and trapper, obviously traps would be most important to you.  If you are a caregiver and need to deliver food to the bedroom of a sick relative everyday, then a tray might be one of your most useful tools.

you will have to expand on your question (e.i.  what is the downward action force on the nail?)

Bridge bolts hell yeah Its not a company name though its a product Ive got some on me 10 year old board they are the shnizle what they do is replace your screws that hold the trucks on.  Vibration from riding causes the screws to come loose well these bridge across two holes so you need four bridge bolts per board.  you can tighten the crap out of them and they wont pull through your board and also the dont get all stripped out like screws do and you never need a screw driver just a wrench.  I think I ordered the from California Cheap Skates back in the day I dont know if they still have them or not.  If you can get them you should you will love them, definately worth looking into. Good Luck   Oh yeah Grind king trucks are cool to in stead of a long bolt and nut stiking out on your king pin its reverse and uses a hex wrench they dont hank up as mush and you can grind alot faster and farther.

Nail polish and stop stressing!!! ALWAYS have a nail file with you so if you get a jagged edge, your not tempted to "nibble" it smooth.

The word nail comes from the latin "unguis", which does mean finger nail, but also "claw". This may be why we use it to mean "a pointed fastener".

Depends on your application.  Try both, and see which one suits you best.
