Double drum bolt is a kind of single and double-sided riveting bolts. It is a new standard part of blind riveting. In riveting, deformation or interference are fully used to connect the riveted parts. Riveting should be carried out with common tools (manual, electric and pneumatic). The product has the characteristics of convenient use, high efficiency, low noise, good moisture resistance, and can reduce labor efficiency.

Double drum bolt is a high toughness standard part with broken core and double drum. The drum bolt is very suitable for the riveting place where it is troublesome to select the general bolts (which must be riveted from both sides), so it is widely used in engineering construction, mechanical equipment, cars, ships, airports, shipping containers, equipment, household appliances, furniture, etc. Among them, the open mouth flat round head rivet is the most widely used, and the countersunk head rivet is suitable for the riveting place which must be smooth and has a viewing angle, and is not affected by the load. Closed rivets are suitable for riveting places with high load and certain sealing characteristics.

Double drum rivet commodity raw materials: Aluminum 5050 / 5052 / 5056 / 5154, iron, stainless steel plate 304, etc. Commodity diameter: 3.3mm, 4mm, 4.8mm, 6.4mm. Length: 5mm-40mm. There are three kinds of drum bolts: single drum bolt, double drum bolt and multi drum rivet. After riveting, the bolt core will pull the tail end of the bolt body into a pair of drum bolt heads, and then clamp the two riveted parts, which can reduce the working pressure on the surface of the parts.

Aluminum and metal materials that meet the requirements can replace several standard parts. Very good to make up for small round holes and large spherical bubble tail, thin plate is the ideal riveting raw material. All round tightening work ability, excellent hole filling capacity, regulator shear and compressive strength, good plate rolling ability, keeping nail core, Hengtai stainless steel plate type can show high corrosion resistance and semi hollow rivets can be used in high temperature natural environment. A variety of special installation tools can be selected to replace several standard parts, which are suitable for plates with different thickness, Reduce the inventory of standard parts and simplify the inventory control, can compensate for irregular, super large, slotted or displaced holes, can clamp the plate in the non-standard hole, strong seismic connection, because the anti-theft lock cylinder is not easy to cause damage and electrical equipment problems.
