Introduction to Hexagonal Welding Nut
Hexagonal welding nut is a type of hexagonal nut specifically designed for welding. Its shape is hexagonal, with one side identical to a standard hex nut and the other side featuring three welding points and a protrusion. These three welding points are used for welding, while the protrusions are used for positioning to ensure the accurate position of the nut during the welding process. Hexagonal welded nuts are widely used in industries such as automobiles and molds, and some specific application scenarios require nuts to be connected to connectors through welding instead of traditional bolt connections.
The implementation standard for hexagonal welded nuts is GB/T13681-1992, which specifies in detail the dimensions, types, and technical conditions of welded hexagonal nuts with eight thread specifications of M4-M16. In addition, the standard also specifies the materials, threads, mechanical properties, tolerances, surface roughness, surface treatment, surface defects, acceptance and packaging, and guaranteed load for welding hex nuts. The weight of hexagonal welded nuts is also specified, and the weight of every 1000 welded hexagonal nuts must meet the standard requirements.
Compared with conventional hex nuts, the use of welded hex nuts is more flexible and efficient, especially suitable for situations where conventional bolt connections cannot be made, such as thin or irregularly shaped connectors. The welding process melts and mixes the metal at high temperatures, and forms a strong connection after cooling. The strength of this connection method is usually greater than that of the parent material, so it is widely used in industries such as automotive seats, sheet metal chassis cabinets, molds, ships, railways, etc. When choosing to weld hex nuts, consideration should be given to the actual application environment and requirements. For example, when used in corrosive environments, materials with better corrosion resistance should be selected. In addition, the control of welding quality is also crucial, including removing dirt from the welding area to ensure welding quality, and taking appropriate cooling measures to prevent the impact of welding heat on nut performance.
In addition, the advantages of hexagonal welded nuts include the reliability of their connection function, which can effectively improve the stability and durability of assembly, which is particularly important for applications that require frequent use or heavy loads. For example, in the automotive industry, hexagonal welding nuts are used to secure components such as seats and instrument panels, ensuring that they do not loosen or fall off during use, thereby improving the safety and comfort of cars. In mold manufacturing, this type of nut is also used to secure various components of the mold, ensuring the accuracy and durability of the mold. In ship and railway construction, hexagonal welding nuts also play an important role in connecting and fixing various structures and equipment, improving the stability and safety of the overall structure.

A double-stacked self-locking washer is a special mechanical connector designed to prevent bolts from loosening, especially in high-vibration or high-load environments.It consists of two spring washers nested inside each other in an S-shaped configuration. The outer spring washer has ends that bend inwards, while the inner spring washer has ends that bend outwards, creating a two-way self-locking feature.The working principle of this washer is based on elastic deformation. When placed between connecting parts, the inner curved part of the outer spring ring interlocks with the outer curved part of the inner spring ring, creating a locking force that prevents the connecting parts from loosening under vibration or load.The advantages of the double-stacked self-locking washer include high reliability, easy installation, and a wide range of applications.It is suitable for various mechanical connections, such as threaded connections and pin connections, and is widely used in industrial production and machinery manufacturing, especially in the automotive manufacturing process, where it is often used to connect engine and chassis systems to improve the safety and reliability of the car.
