Material of Fish Bolts
2022-10-14
There are many applications of fasteners in life.Fish Bolts is one kind of fastener used in railway,which plays a key role in the fishtail plate. Fish Bolts is also known as fishtail screw or rail bolt,its shape is different from hexagonal bolt,root for semicircle head,round head has two protruding inside.Fishtail bolts are usually used in primary color applications without surface treatment. According to the type of rail,the diameter of the bolt is different because of the difference in the diameter of the rail,and the length of the bolt is not necessarily the same because of the thickness of the Square Head Fish Bolt.The diameters are:Φ14,Φ16,Φ18,Φ20,Φ22,Φ24.The material has 4.8 grade 8.8 grade,10.9 grade strength fishtail bolts,ordinary joint bolts and strength insulation joint bolts.Its manufacturing process is usually hot press forming friction press,but also cold heading forming.It is mainly used in metallurgy,coking,iron and steel,crane and other industries of transportation rail laying in the connection fastening rail joints,sometimes also replaced by hexagonal bolts. It is usually mainly used in the laying of the track,which requires us to check the application after the application,which not only reduces the workload in the later stage,but also makes a basic step for reducing the failure.It is a connecting part in track laying,so it is particularly important.
