People who often deal with hardware know that fasteners often appear locked during use. Locking fasteners will cause the operation of the fastener itself to be ineffective, that is, it cannot be disassembled or continued to be fastened. Pieces. What causes this to cause the fasteners to lock up? How can I avoid the state of the fasteners locking up? China Stud Supplier - Zhejiang Weigao Standard Parts Co., Ltd. . 1. Reasons for fastener locking The locking of fasteners generally occurs on products made of stainless steel or alloy materials.This is because these metal materials themselves have the ability to prevent corrosion.Once the metal surface of the fastener is damaged, it will appear to oxidize. Layer to provide protection against the intensification of rust, but when the fastener is locked, the pressure and heat generated by the force will destroy the oxide layer, causing blocking or shearing between the metal threads, and then the phenomenon of adhesion, also It is deadlocked. 2. The method of fasteners to avoid locking: The locking of the fasteners cannot be completely eliminated, but we can reduce the chance of locking by paying attention to various factors, such as ensuring the load capacity of the fasteners and choosing screws and nuts with more tensile strength. Whether the thread of the fastener is clean also has a certain effect on whether it locks up.When the thread is rough or unclean, lockup occurs more often, so be sure to clean the fastener and remove iron debris or Dirt. Industrial Bolt Factory's fasteners must be lubricated, but the consequences are very serious. The heat generated by the force on the metal parts will be effectively reduced. This is because it can reduce the locking of the fasteners.
