What is the difference between a bolt and a screw?
Bolts and screws are two widely used connecting elements present in almost every home workshop, as well as at many professional production enterprises, in workshops, etc. Theoretically, everyone knows the difference between them - we can say at first glance what a screw is a screw And what is a screw. However, can we actually determine the differences between them? It turns out that it is not as simple as it might seem. Material
Scuropes are used to screw into threaded holes in metal elements. Shurups are products that are screwed into soft materials, especially into a tree, without preliminary drilling holes in the material. The above proposals are often used to introduce separation into connecting elements. Unfortunately, definitions based on the designation of elements for specific types of materials are not accurate and there are some exceptions.
Winding method
Another criterion by which we divide the connecting elements into screws and bolts every day is a way of screwing them. The screws have grooves or a nest on the heads - with the help of a screwdriver of the corresponding shape, we can screw them into the selected place. The bolts do not have such cutouts, mounted with the help of keys: end or divorce. Form of the head
Looking for further differences between bolts and screws, we approach the shape of the head. The elements used in the house are easy to divide taking into account this criterion - the screws used in amateur applications have a hexagonal head or a hexagonal slice, the screws have a round head. However, if we go beyond the scope of elements usually used in home workshops, we will note that there will be exceptions among them. Examples are screws with a hexagonal head or the so-called rym bolt. The latter could not be attributed to any of the categories, they use the aforementioned division. So this is not enough.
So is there a way to distinguish a screw from a screw? It turns out that the only criterion for division is the position of the head after fixing the element. What does it mean? In a nutshell: after fixing the screw in a given place, his head should protrude above the surface in which it was placed. Self -tapping screws, on the contrary, have secret heads, which means that after screwing them into a given surface remains even.
