Product Description

Type UR projection weld studs have a large circular flat head shape, with a smooth and flat surface, which can increase the contact area with the surface of the connected component. They are often used in the connection of thin plates and decorative components.

Product Features

Fully threaded studs with oval point essentially have threads running through the entire stud, with one end gradually narrowing to an oval head. It is like a guide, guiding the studs smoothly into the holes during installation. This means that you are less likely to damage the threads on the parts, especially when operating manually or in narrow Spaces. Use a standard nut at the other end.

After welding is completed, the type UR projection weld studs form a high-strength connection with the workpiece, capable of withstanding large tensile forces, shear forces and vibrations. Even during long-term use, when subjected to external forces or equipment vibrations, it is unlikely to loosen or fall off, such as in the welding of connection nodes between steel beams and steel columns in building steel structures, which can ensure the stability of the building structure.

The threaded processing accuracy of UR projection weld studs is high. They fit tightly and smoothly with standard nuts or components with internal threads, and there will be no problems such as sticking or thread slippage during installation. This ensures that the subsequent installation of other components can be completed with ease and accuracy, thereby improving the overall assembly quality.

The type UR projection weld studs are very easy to operate and do not require a complex positioning process. During the welding process, the special raised design on its head enables it to quickly adhere to the welding piece. Once the welding equipment is powered on, the raised part melts rapidly, firmly welding the stud onto the welding piece. This significantly reduces the installation time and enhances production efficiency.
