Screw, screw, self -tapping screw, bolt, washer and nut: what's the difference, differences?

Differences and concepts of the bolt, nuts, screws, screw.

There are a huge number of fasteners that are used in construction. Their main purpose is to connect the details, as well as keep the design holistic. Among the fasteners, goals, nuts, screws, bolts, as well as screws, self -tapping screws are distinguished. All these products differ from each other not only by appearance, but also by purpose.

What is a screw, a screw, a self -tapping screw, a bolt, a puck and a nut, what does it look like, what is intended for?

The puck is a fastener that is auxiliary and is placed under the head of the nut. The main purpose of such a product is to increase the area of \u200b\u200bpressure, as well as prevent the destruction of other fasteners. In addition, the washer prevents the development of fastening and makes it more resistant to various kinds of mechanical influences.

Shurup - a fastener element, which is a type of screw, differs from it in that it has a thick rod, an outer thread, and a pointed tip. This contributes to a more easy and simple entry into a solid surface. Namely in wood or concrete. Most often, special holes are made for screws, which are filled with relatively soft material. This is usually a tree.

A screw is also a fastener, a variety of which is a self -tapping screw or screw. The main feature of the fasteners is that it is a rod with external carvings and a fairly large head for screwing. Most often, special holes are made on the head so that the screws can be twisted with a screwdriver. Or make special notches to screw the products using a special key.

Bolt is a fastener that is a cylinder with a fairly high hexagonal head. Most often works with the nut in pairs, and is used to connect some parts.

A nut - a fastener inside which is a thread is used complete with a screw or bolt. Typically, nuts are made by hexagonal in shape so that they can be attached with a key.

The screw and the bolt are outwardly very similar to each other, and many can confuse them. But they are used in completely different industries. The fact is that there is a feature in the design, because of this, the bolt is mainly used in order to fasten parts using a nut. That is, on the one hand there will be a bolt, in the middle there will be some kind of detail. On the other hand, there will be a nut that will fasten all this.

The screw differs from the bolt in that it is not used with a nut, but most often used separately. That is, in the detail itself there is a thread into which the screw is screwed. Thus, the connection is carried out, that is, additional nuts for the screw are not used.

The screw differs from the screw and the bolt in that it has a more rare thread and pointed tip. Used without a nut and washer. Most often, its surface is self -cutting, that is, when applying a certain force, self -tapping screws can be screwed into a wooden surface, without cutting preliminary threads. Wandies and bolts are not used for these purposes, because they do not have a pointed tip and they do not have a self -cutting characteristic.

Actually, self -tapping screw is a variety of screws, but is distinguished by some signs. The fact is that the technology for manufacturing self -tapping screws is somewhat more complicated. Since more solid, durable materials are used for manufacturing, which can destroy the surface with a certain effort. For example, self -tapping screws can be screwed without the manufacture of a separate hole, it is enough to make efforts. Sounded from a certain force. Thus, the screw will enter the surface of the tree or other material tightly. In order to introduce a screw, you must first make a hole on the surface.

That is, the screw itself cannot be screwed without making an additional hole. Since the material is quite fragile and not so strong. They are not so sharp, so it is difficult to winger without an additional hole. In addition, the screw has not such a greater height and less thread step. At the same time, the tip of the screw is more acute than that of the screw.

The nut differs from the bolt in that these are two fasteners that are used in pairs. That is, the nut has an internal thread, the bolt has an outer. Accordingly, the nut is wound on the bolt. Thus, the structural elements are connected.

The nut from the washer is also significantly different. The fact is that inside the nut has a thread. A washer is an element that is usually used to compact the connection between the bolt and the nut. That is, it is invested immediately before wrapping the nut. This helps to improve the connection. At the same time, the possibility of promoting, developing the nut and its removal from the surface of the bolt is minimized. Washers are different, both flat and curly. They are also called grovers. Additional pressure improves the clutch of the bolt and nut and makes the connection of parts more reliable.

As you can see, there are many fasteners and parts that are used to connect components, mechanisms and structures. They have a large number of differences and are used in each case.
