Q:How is the screw nailed to the wall

First with the diameter of the nail into the half, and then come up with that nail, then screw into the screw

Q:What is the fastener and others?

Definition: Components used to join and fasten components.

Q:There are some screws, is installed in the electrical, power, electronic products on the material, ask how to correctly install the screws?

After we understand the characteristics of the screw, we can proceed to the next step. For example, we use the hands of a 8.8-wide hexagonal screws, then we have mastered the 8.8 hexagonal screws, the use of screws can be used to wipe some of the oil, so that we can protect the screws, in the invisible Which extended the life of the screw. And we have to use the 8.8-grade hexagon screw in the process, we will be able to know that we need to properly protect the screw head inside the hexagon, to prevent 8.8 grade hexagon screw skid, because we know 8.8 grade hexagon screw More difficult to take out. Then we can think of this screw should be used in what place? We can not put a small number of digital screws on the large industrial above, so that the screws can not withstand the pressure of large industrial above, so we need is to help the screw to choose a suitable place, so the screw on the matter The value of the.

Q:what parts do Fasteners include

Screw: also by the head and screw two parts of a class of fasteners, according to the use can be divided into three categories: machine screws, set screws and special purpose screws. The machine screw is mainly used for a fastening screw hole part, with a through hole between the parts of the fastening connection, no nut matching (this connection is called the screw connection, also belong to the detachable connection; Used in conjunction with nuts for fastening connections between two parts with through holes.) The locking screw is mainly used to hold the relative position between the two parts. Special purpose screws such as rings are used for lifting parts.

Q:A general set of screws have a few nuts, bolts, washers?

You want to see the specific requirements and uses. There is also a nut, a bolt, and a flat pad

Q:Do not use self tapping screws

No provisions of self tapping screws without gasket, but because the self tapping screws are often used in non regular removal of the place, and will not force big place, so unless there is a need to increase the stress area of the nut, generally do not have to use the gasket.Self tapping screws also have a flat head, in this case, the general should be smaller than the top of the back, or else they can not get into the hole in the ah.

Q:Fasteners often say that the nature of galvanized oxidation is what it means

Fasteners, is a fastening connection with the application of a very wide range of mechanical parts. Fasting, widely used in industries such as energy, electronics, electrical appliances, machinery, chemical, metallurgy, mold, hydraulic, etc., in various machinery, equipment, vehicles, ships, railways, bridges, construction, structure, tools , Chemical, instrumentation and supplies, etc., can see a wide range of fasteners, is the most widely used mechanical base pieces. It is characterized by a wide variety of specifications, performance purposes vary, and standardization, serialization, the degree of generalization is also very high. Therefore, some people have a national standard of a class of fasteners called standard fasteners, or simply referred to as standard parts.
