Notes

The English name of the riding screw is U-bolt, which is a non-standard part. The shape is U-shaped, so it is additionally called U-bolt. There are strings on both ends that can be integrated with a nut. It is mainly made use of to take care of tubular objects such as pipes or sheet items such as automobile plates. The springtime is called a riding screw since it repairs the things similarly as a person riding on a horse. According to the string length, it is separated right into two types: full string and non-full string.<br>
According to the thread type, it is divided into two kinds: coarse string as well as great string. The crude thread kind is not shown in the bolt mark. Bolts are separated right into 8 grades of 3.6, 4.8, 5.6, 6.8, 8.8, 9.8, 10.9, 12.9 according to their performance grades. Among them, screws of grade 8.8 and also above (including grade 8.8) are constructed from low-carbon alloy steel or medium-carbon steel and also are heat-treated (satiated) + Tempering), normally referred to as high-strength bolts, usually described as regular screws listed below 8.8 (not consisting of 8.8).

An and also B grades are fine-tuned screws, and C grade is rough screws. For attaching screws for steel structures, unless otherwise specified, they are normally average crude grade C screws. The processing methods of various grades are various, and the equivalent handling methods are typically as adheres to: ① The screws of quality An and also B bolts are processed by turrets, with smooth surface and also exact dimension.

application

There are numerous names for screws, and everyone's name might be various. Some people call it screws, some individuals call it bolts, and some people call it bolts. Screws are tools that utilize the physics and also mathematics of the oblique rotation of the friction as well as the object force to progressively tighten up the objects.

Anyway, bolts are utilized in many places. Such as precision bolts made use of on electronic products. Mini screws utilized in DVDs, cams, glasses, watches, electronics, and so on; basic screws used in tvs, electrical products, musical tools, furniture, etc; as for design, construction, and also bridges, huge screws and nuts are utilized; transportation equipment, trams, automobiles, as well as aircrafts And so on, are used for both large and also little bolts.



Among them, screws of grade 8.8 as well as above (consisting of grade 8.8) are made of low-carbon alloy steel or medium-carbon steel and are heat-treated (quenched) + Tempering), generally referred to as high-strength screws, typically referred to as regular screws below 8.8 (not including 8.8).


An and also B grades are improved bolts, and also C quality is harsh bolts. For linking ZHONGNING for steel frameworks, unless otherwise specified, they are typically ordinary unrefined grade C bolts. The handling methods of different qualities are different, as well as the equivalent processing techniques are normally as adheres to: ① The bolts of grade An and B screws are processed by turrets, with smooth surface area and also exact dimension. Miniature screws utilized in DVDs, video cameras, glasses, watches, electronics, and so on; basic bolts made use of in tvs, electric products, musical instruments, furniture, etc; as for design, building and construction, and bridges, big screws as well as nuts are utilized; transport tools, airplanes, trams, and autos And so on, are made use of for both little and also huge bolts.
