Double drum bolt is one of many rivets. In multi drum riveting, when riveting, the rivet core will pull the tail end of the bolt body into two pairs of drums or multiple drum lines to clamp the two parts to be riveted, and can reduce the working pressure on the surface of parts, which is suitable for riveting thin parts.

Generally, the application scope of double drum bolt is used in vehicle, ship, engineering construction, mechanical equipment, electronic devices and other fields.

The main features of double drum bolt are: 1. The ability of tension and bending resistance of regulator; 2. Heat resistance; 3. Certain closed type; 4. Used in sheet metal raw materials; 5. Showing strong vibration joints; 6. Reducing the working pressure of bolts on the product workpiece to ensure that the product workpiece is not easy to deform.

Rivets are the key parts of medical equipment for airlines, so the application of rivets has certain attention. Different classification of open all iron core pulling rivets has different effects. Today, Dongguan City solid hardware to give everyone a talk about some key classification of rivets!

2. Moisture proof bolt

Closed countersunk head rivet: key raw materials are aluminum, iron, stainless steel plate, copper

3. Structural bolts

The major difference between structural bolts and general bolts is that in addition to the high compressive strength, a more typical feature of the rivets is that the core is locked in the riveting body after riveting. Many people may feel that the core of general bolts is also stored in the riveting body after riveting, The structural bolt is mainly used for cars, railway lines and airlines. Some of the products that are necessary for the market are also sold, such as open mouth painted bolt, single drum bolt, double drum bolt, fumeilai bolt and Qingle bolt
