Do you know how to avoid the seizure of stainless steel screws and stainless steel nuts? Today Stud Manufacturer-weigao will explain to you how to avoid the seizure of stainless steel screws and stainless steel nuts.

Generally, stainless steel screw manufacturers do not recommend the use of stainless steel screws and stainless steel nuts together. Due to the material of stainless steel, stainless steel screws are often seized after they are tightened with stainless steel bolts and stainless steel nuts during the assembly of low-temperature pipeline flanges. It is difficult to remove it. So if stainless steel screws are used in conjunction with stainless steel nuts, which aspects should we solve the seizure state?

1. Cryogenic treatment can be done to intrude stainless steel screws into a low-temperature liquid nitrogen box for a certain period of time to reduce the deformation caused by temperature differences and metallographic changes, thereby improving the sealing performance of the valve at low temperatures.
2. Change the stainless steel nut to other materials, or change the basic one to other materials. This avoids the seizure of stainless steel bolts and stainless steel nuts.
3. At present, there is a technology that can prevent the screw and the nut from biting.
4. When Fasteners Suppliersuses stainless steel screws and stainless steel nuts, apply some grease on the stainless steel screws to avoid the phenomenon of stainless steel screws seizing.
