What Is A Screw
A screw is a small metal post with threads going down around it. At the end of the post is a head with different indentations, depending on the type of screw. A screwdriver tool is used to insert and remove the screw from the hole. To insert or tighten a screw rotate it to the right, to loosen a screw rotate it to the left. An easy way to remember this is with the saying “righty tighty, lefty loosey”....
