China DIN 929 Welded Nuts Suppliers - Hexagonal Welded Nuts Factory, Grade 4.8 to 12.9, Various Material Options

Functional Configuration Functional

Hexagonal welded nuts serve as connections. Use a welding machine to connect the hexagonal welding nut to the mother body, and then use screws to fix the required object. Generally used in conjunction with spot welding machines, it has good welding performance and fast efficiency. This type of nut is widely used in industries such as automotive seats, sheet metal chassis and cabinets, molds, ships, railways, etc.

Product features features

Hexagonal welded nuts solve the problem of ordinary nuts being unable to secure the parent body. There are three welding points and a circular protrusion on one side of the nut. The protrusion is used for positioning, and the solder joint is used for welding. Firstly, punch out a positioning hole on the mother body, position the protrusion of the nut on the hole, and then use a spot welding machine to weld the nut onto the mother body. The welding principle is to melt the three welding points of the nut at high temperature, causing the welding points to melt on the parent body, achieving the welding effect. This connection method belongs to non detachable connection.

Superiority products

Projection welding has accurate positioning and consistent dimensions, with uniform strength at each point and reliable welding. Projection welding can ensure that the threads do not anneal without reducing accuracy, and the appearance of the welded parts is beautiful with high productivity. There is no harm to the human body caused by CO2 gas and coating smoke, which can improve the working environment.

Shortcoming PRODUCTS

Due to incorrect selection of process parameters, the protruding welding nuts are not firmly welded, and semi-finished parts are prone to falling off during transportation or transportation.

Application and Development History Application

With the continuous improvement of the quality of welded nuts and the needs of the industry, various types of welded nuts have emerged. The application of welded nuts is becoming increasingly widespread, especially in the automotive industry, where they are applied in important parts such as chassis beams, transmissions, and seat belts. Hexagonal welded nuts are convenient to use, highly efficient, and have a beautiful welding appearance. More and more products are using hexagonal welded nuts.
