The beneficial effects of Guangdong Yueluo Hardware Industry Co., Ltd. are: the chip nut provided by Guangdong Yueluo Hardware Industry Co., Ltd. has a circle of serrated teeth protruding outward on the edge of the welding end face. During welding, excess solder After overflowing, it flows into the peripheral serrated convex tooth gap. In this way, on the one hand, the solder on the welding end face can be made uniform, and the welded chip nut can be neat and beautiful.

The grooved embedded parts are pre-embedded in concrete, and then placed in the groove with T-bolts. After adjusting the fixed position, the fixed object is locked with a nut to achieve the fixing effect. When the grooved embedded parts are embedded vertically in the concrete or at a certain angle to the horizontal line, the T-bolts are likely to move in position before they are tightened. In particular, when fixing heavy equipment, multiple T-bolts are required, and multiple groups of workers are required to help and positioning is difficult, and the installation process is complicated.
