Methods To Prevent Fastener From Seizing

Through the previous analysis, it can be seen that once the stainless steel fastener seizes, disassembly is extremely inconvenient, even some methods or special tools are time-consuming and laborious, so doing a good job of stainless steel fastener seizing prevention is particularly important. As a professional fastener manufacturer, Xinchi Fastener Company has many years of experience in the fastener industry. TAs a professional fastener manufacturer, Xinchi Fastener Company has many years of experience in the fastener industry. Next, we introduce several methods to prevent stainless steel fasteners from seizing.

1. Choose bolts and nuts of different materials to match.
2. Improve the performance of the fasteners themselves. For example, adding film to the fastener thread to prevent seizing, but this method costs a lot and is rarely used at present.
3. Clean the thread, and check whether the teeth are complete and whether there are impurities between the continuous teeth.
4. Apply a lubricant, such as molybdenum disulfide, butter, etc., to the thread. The coating should be uniform and full of threaded tooth base, covering the length of the bolt head about (10~15)mm.
5. During the fastening operation, screw the nut or bolt into the (2-3) buckle wire by hand first, and then tighten it with a torque wrench or sleeve wrench. Tighten with even force and tighten perpendicular to the axial direction of the bolt. Do not use a movable wrench or an electric or pneumatic wrench.
6. Avoid excessive torque or speed when using an electric or pneumatic wrench for pre-tightening. Ensure that the nut stops working when it contacts the pad, and then tighten it with a torque wrench. The tightening torque does not exceed the specified torque value.

Through analysis and conclusion, the seizing of stainless steel bolts and nuts is mainly due to the excessive pressure and high temperature between the threads damaging the oxidation layer on the surface of the dental grain and leading to direct contact with metal material, further blocking, shearing, and bonding. Therefore, in the process of using stainless steel fasteners, we not only need to understand the symptoms of fastener seizing but also need to understand the principle and reason. We should know how to solve the problem after the occurrence of seizing and do a better job of stainless steel fastener seizing prevention measures so that the use of stainless steel fastener life is extended.
