Locking of stainless steel fasteners is a common problem，The cause may include vibration、Temperature change、corrosion、Improper operation and other factors。To prevent stainless steel fasteners from being locked，Several approaches can be taken：

one、Reasonable selection of fastener materials

• Select according to the use environment：The material selection of stainless steel fasteners should be determined according to the specific use environment and requirements。Such as，At a high temperature、In highly corrosive environments，High temperature resistance should be selected、Corrosion-resistant stainless steel material。

• Consider mechanical properties and heat treatment status：In addition to the material itself，The mechanical properties and heat treatment state of fasteners should also be selected according to the specific situation，To ensure that it has good performance during use。

two、Optimal design

• Avoid stress concentration：When designing stainless steel fasteners，The use environment and requirements should be fully considered，Optimize its structure and size，Avoid stress concentration。

• Reasonable distribution of preload：Through reasonable distribution of preload force，The fasteners ability to resist locking can be improved。

three、Proper installation and use

• Operate strictly according to the instructions or specifications：When installing and using stainless steel fasteners，Operation should be carried out in strict accordance with the instructions or specifications，Avoid excessive force or tapping，So as not to cause changes in internal stress。

• Regular inspection and maintenance：In the process of use，It should be inspected and maintained regularly，Identify and deal with problems in a timely manner，Avoid exacerbating the problem。

four、Additional lubrication measures

• Use lubricant：Adding lubrication measures to the surface of stainless steel fasteners can effectively reduce friction，Avoid stuck and locked situations。Common lubricants are grease、Lube oil，When used, it should be selected according to the specific situation。

five、Other preventive measures

• Reasonable selection of screw length and specifications：To expose the nut after tightening1~3Per tooth pitch，Avoid too long or too short resulting in locking。

• Keep the thread surface clean：Before use，Ensure that the surface of the thread is free of dust and debris，You can apply water wax or add lubricant to reduce friction。

• Avoid fast rotation：During the tightening process，Rapid rotation should be avoided，To prevent the temperature from rising rapidly and causing locking。

• Use anti-lock products：Consider using products such as anti-lock nuts，These products are specially treated，Like waxing、Boiling oil，It greatly reduces the chance of locking up。

• Properly reduce the assembly tightening speed：Use a torque wrench or socket wrench whenever possible，Avoid using adjustable or electric wrenches，Because the electric wrench often causes the locking speed to be too fast，The temperature rises rapidly and locks up。

• Use washer：The use of washers can effectively prevent the problem of over-locking，This reduces the risk of locking。

To sum up，Preventing stainless steel fasteners from being locked needs to start from many aspects，Including reasonable selection of materials、Optimal design、Proper installation and use、Increase lubrication measures and take other preventive measures。Only in this way can we ensure the normal use of stainless steel fasteners，Improve its service life and stability。
