Why Do Self-locking Stainless Steel Cable Ties Use Steel Balls For Locking?

The steel balls are typically made of carbon steel or stainless steel, with their diameter precisely controlled to the millimeter level. The thickness and hardness of the metal zip ties directly affect the sliding resistance of the steel ball; too thick a ball increases the required tensile force, while too thin a ball may deform. This is why different specifications of metal cable ties require corresponding matching tools.

The precision machining of the head ensures the accuracy of the groove depth and angle. The groove design must not only accommodate the steel ball but also provide sufficient tensile strength. When the stainless steel zip ties is subjected to tensile force, the depth to which the steel ball is inserted into the groove determines the load-bearing capacity of the entire assembly.
