All fasteners are custom-made by us through mold making, and when tightly packed, there is no sound when carried. Many cheap fasteners on the market make a clicking sound when carried or slightly shaken, which is quite awkward.When opening the mold, we adjusted the proportion of materials used for the fasteners, which are more cold resistant, impact resistant, and high-temperature resistant than ordinary fasteners in the market. They have stronger toughness and are less prone to cracking and deformation; At minus 30 degrees Celsius in cold regions, it is less likely to break than iron fasteners.
