Product introduction

Screw Specifications

Screw head table

screw generally includes a screw head, a screw part and a screw tail. In the traditional screw processing, the screw head and the screw part are punched out first, and then the threaded part is processed on the screw shank through the turning process. When the screw head is traditionally punched, the screw head is easily damaged due to the large punching force.

At present, due to the installation position determined in the design process of the traditional thrust cylinder in China, the corresponding position of the piston rod and the clamping arm is fixed, and it is impossible to ensure that the workpiece can be clamped while the workpiece is thin. It is not conducive to the use of such products when clamping. Secondly, when the workpiece is assembled or welded, it not only needs to be tightened in a certain direction, but also needs to be positioned, so as to ensure the accuracy required for processing. When a workpiece is fixed in this way, it must be realized by adding a mechanism, which will increase the complexity of the system and bring inconvenience to installation and maintenance.

All-aluminum blind rivet The body of the rivet is also made of high-quality aluminum wire, which is beautiful and durable after riveting and will never rust: Compared with ordinary blind rivets, rivets have lower riveting strength and are suitable for connectors with relatively soft materials. . Split Stainless Steel Rivet: This rivet is a high-tension, corrosion-resistant choice. Round head rivets are mainly used in riveting occasions subject to large lateral loads, and are the most widely used. Flat cone head rivets are often used in riveting occasions with strong corrosion such as ship hulls, boiler water tanks, etc.
