Question

A. How are screws different from nails?
b. Which one will you choose to hold the things tightly and why?

Answer 1

Answer:

a) A screw has threads on the shaft while a nail is smooth. Since that is the case, a smooth nail can be fastened to a material using a hammer or any pounding force. Since a screw has threads, you can not use a hammer, you need a screwdriver or some tool that turns the screw into the material.

b) i will choose the nails cause its a lot stronger

Answer 2

When deciding between nails and screws, keep in mind that nails are less brittle, so they provide greater shear strength.
