DIN929 welded hex nuts are mainly used in scenarios that require high-strength connections and special shaped connections. This type of nut is connected to the connector by welding and is suitable for situations where conventional bolt connections cannot be made, such as when the connector is too thin or irregularly shaped. The welding process is equivalent to turning two separate parts into a whole, melting the metal at high temperature, mixing it together, and then cooling it. An alloy is added in the middle, relying on molecular force, and its strength is generally greater than that of the parent material.

DIN935-1 hexagonal slotted nuts are mainly used to fix the front and rear axles of vehicles. By tightening the screws that pass through the front and rear axles, the frame and tires are fixed together. In order to prevent the nut from loosening, it is usually fixed by using an open-ended pin that passes through the groove of the slotted nut. The open-ended pin needs to pass through the middle of the wheel axle screw, and usually both ends of the wheel axle screw need to be drilled. The diameter of the hole and the width and depth of the slotted nut groove determine what specification of open-ended pin is selected.
