2021-08-23
Under normal circumstances,the fishtail bolt is mainly used in the rail joint splint connection,play a fixed role,sometimes fishtail bolt can also replace hexagonal Bolts.In general,fishtail bolt is mainly used in the metallurgical industry,coking industry,iron and steel industry in the track laying,rail and rail joint connection fastening.Fishtail bolt is a kind of product which is widely used in heavy industry.It is also very convenient to use and the price is low. 
The fishtail bolts can be divided into different types according to the material and specifications.Users can choose suitable and practical fishtail bolts according to the actual needs.High strength fishtail bolt is also one of the many fishtail bolts,and can be divided into different performance classes.The fish tail bolt of 8.8 grade or above is made of low carbon alloy steel,medium carbon steel and heat treated.The performance grade of fishtail bolts consists of two parts of numbers,which respectively represent the nominal tensile strength value and flexural strength ratio of the bolt material. High strength fishtail bolts can withstand larger loads than ordinary bolts of the same specification.Mainly 35#steel or other high quality materials,made of heat treatment,improve the strength.
