How To Prevent The Deadlock Of Stainless Steel Fasteners

Dec 24, 2017

Locking or biting is often the case with stainless steel fasteners on the aluminum alloy and titanium alloy. Are these metal alloys inherently corrosion resistant? When the surface is damaged? A thin layer of oxide is produced on the metal surface to prevent further rust. When the fastener of stainless steel is locked, the pressure and heat generated between the teeth will destroy the oxide layer? The phenomenon of blocking or shearing occurs between the metal threads.

When this phenomenon continues to occur? will make the stainless steel fasteners completely locked down? Can not be removed or continue to lock. Usually this series of blocking _ _ cut _ stick _ The chain of the death of a series of actions occurs in just a few seconds? So the correct understanding of the use of such fasteners can prevent this phenomenon.


How to prevent the deadlock of stainless steel fasteners


How to prevent the deadlock of stainless steel fasteners

1. The correct selection of products before use to determine whether the mechanical properties of the product can meet the needs of the use? such as the tensile strength of screws and the guarantee load of nuts. The length of the screw should be selected properly. The 1-2 tooth spacing of the nut is subject to tightening.


2. Check if the thread is rough before using? Is there any iron or dirt in the thread? These things often lead to locking. 3. Can be used before the use of fasteners to make lubrication treatment recommended the use of butter? Molybdenum disulfide, mica, graphite or talcum powder for lubrication


4. Pay attention to the use of the method A, the speed of the rotation force to be appropriate? Don't go too fast. Use a torque wrench or a socket wrench if possible. Too fast will cause the temperature to rise rapidly and lead to deadlock.


B. The direction of the force? The nut must be screwed perpendicular to the axis of the screw. 5. The use of washers can effectively prevent locking problems.
