Machine screws are unique because of their size. Machine screws can have a diameter of up to 0.75 inches, but they can’t be larger. Machine screws have uniform threading that remains the same size from top to bottom. Their small size makes them applicable to a wide range of jobs that other screws. They are similar to bolts except that they have a socket in the head that allows them to be turned by a screwdriver.
