What is the role of E-bolts?

As a Sleeper Screw Supplier, let's talk about the role of E-bolts.E-bolt is divided according to the way the connection is applied: it is used for ordinary and reamed holes. Ordinary main load bearing axial forces can also carry less demanding lateral forces. The bolts for the reaming holes are to be matched with the size of the holes for use in lateral forces. According to the shape of the head: there are hexagonal heads, round heads, square heads, countersunk heads, etc. The hexagonal head is the most commonly used. Generally, the countersunk head is used where the surface of the bolt is required to be smooth and there is no protrusion, because the countersunk head can be screwed into the part. The round head can also be screwed into the part. The tightening force of the square head can be larger, but the size is large.

In addition, in order to meet the needs of locking after installation, there are holes in the head and holes in the rods, which can not loosen the bolt when it is vibrated. Some bolts without threads are to be thin, called thin waist bolts. This type of bolt facilitates the coupling of the force. There are special high-strength bolts on the steel structure, the head will be larger and the size will change. In addition, there are special uses: the T Bolt machine tool has the most used, the shape is special, and the sides of the head should be cut off. Anchor bolts for machine and floor attachments are available in a wide variety of shapes. U-bolts, as mentioned above. There is also a special stud for welding. One end has a thread and one end is not welded. It can be welded to the part and the other side can be screwed directly. Function: A type of fastener consisting of a head and a screw (a cylinder with an external thread), which is to be fitted with a nut for fastening two parts with through holes. This type of connection is called a bolted connection. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection. Because bolts are also a type of railroad accessory, railroad fittings are part of the railroad line, and the rails referred to here include rails, sleepers, joint parts, track beds, anti-climbing equipment, rail stays, and ballasts. As a holistic engineering structure, the track is laid on the roadbed and plays a guiding role in train operation, directly bearing the tremendous pressure of the locomotive and its load. Under the power of train operation, its various components must have sufficient strength and stability to ensure that the train runs safely, smoothly and without interruption according to the specified maximum speed.
