Summary of information:We have more than ten years of experience in screw industry production. The main products are: metric rough hexagon nuts...

To sum up, the chip nut provided by Guangdong Yueluo Hardware Industry Co., Ltd. has a circle of serrated teeth 1011 protruding outwardly on the edge of the welding end face 101. During welding, the excess solder overflows and flows to the periphery. In the gap between the serrated teeth 1011, on the one hand, the solder on the welding end face 101 can be made uniform, so as to ensure that the welded chip nut is neat and beautiful; The welding area is increased, and the firmness and reliability of the welding are improved.

At present, in the production workshop, there is no special tool for removing rivets such as skew, wrong rivets, and multiple rivets. When removing these rivets, workers use homemade rivet removal tools, use a sledgehammer to remove the rivet head, and then use a sharp tool to remove the rivet rod. eject. During the removal operation, sometimes the rivet head will fly out, the speed is high, the danger is extremely high, and the labor intensity is high, which has caused many industrial accidents.

The electroplating of cross recessed screws generally refers to the electroplating of iron cross recessed screws. Stainless steel cross recessed screws are rarely electroplated. The electroplating colors of cross recessed screws are divided into environmental protection and non-environmental protection. Environmental protection blue zinc, environmental protection color zinc, environmental protection black zinc, environmental protection white nickel, etc., non-environmental protection includes white nickel, white zinc, color zinc, black zinc, black nickel, black cladding, blue zinc.

Nuts cooperate with screws to achieve the fixing and connection of components. SMD nuts are generally used in the circuit board industry to fix electronic components. That is, the chip nut is soldered on the circuit board by solder, and the electronic components are fixed by turning the screw. However, when the current chip nut is soldered on the circuit board, there may be uneven soldering, which makes the soldering untidy. At the same time, during soldering, the excess solder overflows from the periphery of the nut, which affects the appearance and may affect its appearance. electrical properties. In addition, the nut is only welded with the circuit board on one end face, and its firmness and reliability after welding are low.

kind of screw provided by Yueluo, the rod body of the screw rod has a thread segment, one end of the thread segment is provided with an annular convex ring on the outer peripheral surface of the rod body, and the distance between the convex ring at the front end of the screw threading direction and the rod core Smaller than the nominal size of the threaded section or the distance from the rear end of the bead to the rod core in the screwing direction is greater than the nominal size of the threaded section.

We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: flange metal self-locking nuts, flat head screws, large standard bolts, single-head isolation columns and other products, we can provide you with products suitable for you fastener solutions.
