For example, if you want to customize  stainless    tapping locking screws , is it necessary to open the mold? For the screw manufacturer, whether the screw needs to be moulded depends on the size, head type, groove type and whether the manufacturer has made this type of screw before.

Self   locking screws  are designed to maintain the benefits of reusability while preventing accidental disassembly when preloading is lost. Self-locking screws virtually eliminate the possibility of components being separated during operation. In order to achieve this advantage, self-locking fasteners must be properly designed, designed and installed. When a part is out of order, the screw vibrates quickly, causing the component to loosen. The main function of the self-locking screw is to prevent backlash when the initial axial tension disappears. By doing so, the  self locking screw s  help to maintain a tight engagement and also help prevent fatigue failure in the joint. Self-locking screws prevent rotation during the first installation and subsequent installation and removal. In addition, the self-locking screw also reduces the tendency of the fastener to fatigue by reducing the vibration transmitted to the fastener. In addition, the insecurity of tr...
