  Square bolt users often reflect why stainless steel fasteners sometimes have locked problems, and similar phenomena often occur when using carbon steel fasteners. Be stainless steel fasteners softer and carbon steel tight? The reason why the firmware is relatively hard? Yes! Stainless steel and carbon steel are essentially different. Stainless steel has good ductility, but its hardness has a certain gap between carbon steel. However, this statement can only be said to be half right. 

  On fasteners made of aluminum alloys and titanium alloys, these types of metal alloys are inherently rust-proof and produce a thin layer of oxide on the metal surface to prevent further deeper rust when the surface is damaged.

  When the square bolt are locked, the pressure and heat generated between the teeth will destroy and erase the chrome oxide layer between them, causing the metal tooth to directly block/shear, and then sticking. When the sticking phenomenon continues (usually no more than one full caliper), the stainless steel fasteners will be completely locked and can no longer be removed or locked. Usually a series of blocking, shearing→adhesive→locking actions take place in just a few seconds. Therefore, understanding the characteristics of stainless steel products and following the correct procedures are all steps to prevent the locking of stainless steel fasteners.
