Socket Head Cap Screw with Spring Washer (SEMS)

Socket Head Cap Screws, also known as CAP screws or bolt, are precision-engineered fasteners made from SCM435 alloy steel. These screws undergo rigorous heat treatment processes to achieve an impressive strength rating of Grade 12.9. The head features straight knurling for enhanced grip, facilitating efficient assembly in automated production lines. The surface is treated with a black oxide finish, providing additional corrosion resistance and a sleek appearance.

To further enhance installation efficiency, each screw is pre-assembled with a spring washer before threading. This ensures that the spring washer remains securely in place during use, significantly reducing installation time. This design is particularly well-suited for applications that demand high precision and efficiency in automated assembly processes.

In addition to our standard offerings, Wei shiun can also customize screws according to specific customer requirements, including the use of alternative materials such as SUS304 stainless steel. Our commitment is to provide high-quality, precision screws that meet international standards, tailored to your unique needs.
