8.8 high-strength stud bolts
Product Name: grade 8.8 stud bolt Product grade: grade 8.8 Surface treatment: stud bolts generally need surface treatment. There are many kinds of bolt surface treatment, such as electroplating, blackening, oxidation, phosphating, non electrolytic zinc sheet coating, etc. However, electroplated fasteners account for a large proportion in the actual use of fasteners. In particular, it is widely used in industries and fields such as automobiles, tractors, household appliances, ins... -
Power U-shaped hoop
Product Description:
Category Power U-shaped hoop
Performance level 4.8, 6.8, 8.8
Material Carbon steel
Surface treatment: natural color (galvanized)
Product grade A grade
Product introduction: Electric U-shaped hoop mainly includes: U-shaped steel pole and U-shaped wooden pole. Discussed because of the word, it looks like an English letter “U”. There are two main types: natural color, hot-dip galvanizing and electro-galvanizing. It is mainly used with the cross arm, which is mainly used to firmly fix the cross arm on the telephone pole.
Main model: U-shaped hoop usually the specifications and dimensions we produce (unit is mm):
16*160, 16*190, 16*210, 16*230, 16*240, 16*260, 16*280, 16*300, 16*350

8.8 High Tensile Bolts
8.8 High Tensile Bolts are made of high-strength steel, or bolts that require a larger pre-tightening force, can be called high-strength bolts. 8.8 High Tensile Bolts are mostly used for the connection of bridges, rails, high pressure and ultra high pressure equipment. The fracture of this kind of bolt is mostly brittle fracture. 8.8 High Tensile Bolts applied to ultra-high pressure equipment, in order to ensure the sealing of the container, it is necessary to apply a larger pre-stress.
Product name:8.8 High Tensile Bolts
Material grade: carbon steel 4.8, 8.8, 10.8, 12.9
Product specifications: m1.6-m64
Product features: simple structure, good acceptability, removable and replaceable
Product application : 8.8 High Tensile Bolts are mostly used for the connection of bridges, rails, high-pressure and ultra-high-pressure equipment. The fracture of this bolt is brittle fracture. High-strength bolts used in ultra-high pressure equipment need to be prestressed to ensure the tightness of the container.
8.8 The difference between High Tensile Bolts and ordinary bolts:
8.8 High Tensile Bolts means that the load it can bear is larger than ordinary bolts of the same specification.
The material of ordinary bolts is made of Q235 (that is, A3). 8.8 The material of High Tensile Bolts is 35# steel or other high-quality materials. After being made, heat treatment is carried out to improve the strength. The difference between the two is the difference in material strength.

8.8 high-strength stud bolts
Product Name: grade 8.8 stud bolt
Product grade: grade 8.8
Surface treatment: stud bolts generally need surface treatment. There are many kinds of bolt surface treatment, such as electroplating, blackening, oxidation, phosphating, non electrolytic zinc sheet coating, etc. However, electroplated fasteners account for a large proportion in the actual use of fasteners. In particular, it is widely used in industries and fields such as automobiles, tractors, household appliances, instruments and meters, aerospace, communications and so on. However, for threaded fasteners, it is required not only to have certain anti-corrosion ability, but also to ensure the interchangeability of threads, which can also be called screwing in here. In order to meet the dual use performance of “anti-corrosion” and “interchangeability” required by threaded fasteners in use, it is very necessary to formulate special electroplating coating standards.
Product specification: M8, M16, M12, M20, M10
Product application: it is used in large-scale equipment and needs to install accessories, such as mirror, mechanical seal seat, reducer frame, etc. At this time, a stud bolt is used. One end is screwed into the main body, and the other end is equipped with a nut after installing the accessories. Because the accessories are often disassembled, the threads will be worn or damaged, so it is very convenient to replace the stud bolt.
