Combination screws are a unique mechanical connection element that uses an intelligent combination of screws and spacers to achieve a more robust and reliable connection. This design makes the screw suitable for applications that require additional sealing or shock absorption.
In combination screws, the threaded part of the screw is combined with a spacer, which can not only provide a good connection force, but also effectively prevent loosening and falling off. At the same time, the presence of a spacer provides gap filling and sealing of the connecting surface, which further enhances the use of the screw.
