Product description
A combination screw, also known as a "Sems screw", is a mechanical connection element with a unique design that uses an intelligent combination of socket combination screw and spacers. This construction offers a double advantage: on the one hand, threaded screws provide a secure connection; Gaskets, on the other hand, effectively fill the gaps on the connecting surfaces, providing additional sealing and shock absorption.
Our company can provide custom screws on demand, and customers can choose different specifications, materials and shapes according to their specific needs to meet the requirements of specific application scenarios. Whether it is the head shape, thread size or gasket type, it can be flexibly customized to ensure the best fit and results.
