How To Reduce The Chance Of Locking Stainless Steel Fasteners?
Jul 24, 2017

  How to reduce the chance of locking stainless steel fasteners?

  Fasteners in the metal fasteners are often due to various causes of corrosion, in the event of corrosion when some fasteners will appear completely locked the problem, resulting in the operation of the fastener itself lost performance, that is, can not be removed or continue to lock On fasteners. The complete lock of the fastener may only occur in just a few seconds, so it is more necessary to know and use the fastener to prevent the lock from happening.

  1, the reasons for fasteners locked

  Fasteners are usually locked in the production of stainless steel or alloy products, because these metal materials themselves have the ability to anti-corrosion, once the metal surface of the fastener damage, there will be oxidation Layer to provide protection to prevent the increase in corrosion, but when the fasteners are locked, the pressure generated by the pressure and heat will damage the oxide layer, making the metal thread between the blocking or shear, and then the phenomenon of adhesion, but also Is locked.

  2, fasteners to avoid locking method:

  ★ fasteners lock can not be completely eliminated, but we can pay attention to various factors to reduce the chance of locking, such as to ensure that the load capacity of fasteners, choose more tensile strength of the screws and nuts.

  ★ fasteners, whether the thread is also locked on the lock have a certain impact, when the thread is more rough or not clean, lock more often appear, so before you use the fasteners to ensure that the cleaning work, remove the iron Or dirt.

  ★ fasteners in the correct and proper lubrication treatment, the metal parts due to the heat generated by the force will be effectively reduced, it will reduce the corresponding fastener lock the probability of occurrence.

  ★ Fasteners use washers and are installed in the correct way, and are less locked.
