In the decoration of building materials, there is such a small object, although its body is small, but the structure is exquisite, the use is also very wide, given its alloy material, it can play its own great role in a variety of occasions. It is the stainless steel screws, today I will pass an article to introduce you to the stainless steel screws in detail, at the end of the article I will also explain in detail the stainless steel screws price, interested in this with me to see it!
Introduction to the price of stainless steel screws
Stainless steel screws according to the different specifications, its price also varies. For example, the M3 series of stainless steel screws, whether Phillips head or round head, the price is very low, in about 4 cents yuan. And a package of self-tapping screws (about 150), its price is generally about 6 yuan, for domestic brands such as Yuan Sheng, its 304 expansion screws, bolts and so on at 3.2 yuan / 10 or so. Many hexagonal screws are not cheap, such as domestic 304 stainless steel hexagonal screws, its price is about 9.8 yuan / 10.
Introduction to stainless steel screws
Stainless steel screws are a type of screws made of a variety of alloy compositions, which, according to the composition of the different, is divided into focus on stainless steel and acid-resistant two kinds of screws, some screws, although there is stainless steel, but does not necessarily acid-resistant and acid-resistant stainless steel screws are often stainless steel, and we are now commonly used to the stainless steel screws, raw material is mainly used in the production of stainless steel screws. Stainless steel screws, raw materials are mainly used is austenitic 302, 304, 316 and "low-nickel" 201, etc., this screw is very strong, durable. Now the stainless steel screws are mainly used in environmental protection equipment, medical equipment and food machinery, open-air occasions and so on.
Stainless steel screws how to maintain
Don't look at the stainless steel screws small size, it is not "all-powerful warrior", in the life of the need for us to be careful on its maintenance! The first thing we need to know is that the characteristics of the stainless steel screws would have been good, but if the very humid environment for too long, or encounter acidic and alkaline chemicals, it will produce a variety of chemical reactions. Therefore, we should install stainless steel screws, to choose the corresponding screws, for example, SUS201 stainless steel screws are not very suitable for use in seawater has a strong salt above, suitable for use in the sea should be used in stainless steel SUS316 screws, because the 316 stainless steel screws to carry corrosion and other properties are much better.
Stainless steel screws need to consider the factors?
Stainless steel screws are screws made of steel with the ability to resist corrosion by air, water, acid, alkali salt or other media, if you want to buy the stainless steel screws you need, you need to consider the following factors.
1, the choice of stainless steel screws corrosion resistance and heat resistance is good;
2, whether the performance is high, whether heat treatment can be strengthened;
3, the production process on the material processing performance requirements;
4, stainless steel screw specifications, how the material standards.
Stainless steel screws are mainly used for: environmental protection equipment, medical equipment, communication equipment, power facilities, electronic products, instruments, food machinery, petrochemical, ship assembly, pumps, valves, pipelines, building curtain walls, open-air occasions, sports facilities, outdoor decoration.
Stainless steel screws installation method:
1, choose an alloy drill bit with the specifications of the outer diameter of the expansion bolts, and then drill holes with reference to the length of the expansion bolts, the depth of the holes drilled to the required for your installation can be, and then clean up the holes.
2, the installation of flat washers, spring washers and nuts, the nut will be screwed to the bolt and the end to protect the threads, and then the expansion bolts into the hole.
3, screw the wrench until the washer and the surface of the fixture is flush, if there is no special requirements, generally hand-tighten and then use the wrench to screw three to five turns.
Stainless steel screws Note:
1, drilling depth: the specific construction depth is better than the length of the expansion tube is about 5 millimeters deep. As long as greater than or equal to the length of the expansion tube, then stay in the ground the length of the expansion bolt is equal to or less than the length of the expansion tube.
2, the internal expansion bolts on the ground requirements is of course the harder the better, it also depends on the object you need to fix the stress situation. Installed in the mixed soil (C13-15) is five times the strength of the force in the brick body.
3, correctly installed in the soil mixture of a M6/8/10/12 internal expansion bolt, it is the most ideal large static force is 120/170/320/510 kilograms.
How about it, I introduced to you the stainless steel screws price of the relevant knowledge you understand clearly, we must pay attention to the quality of the screws when you buy screws, to avoid the use of not long on the occurrence of rust.
