High-Quality Double Sem Screw Products for Superior Fastening

 

Double SEMS screws are pre-assembled fasteners that combine a screw with two captive washers, typically a flat washer and a spring washer. This integrated design helps simplify installation, reduce washer loss, and improve assembly efficiency in high-volume manufacturing applications.

 

Commonly used in electronics, automotive components, electrical equipment, household appliances, and industrial machinery, double washer SEMS screws are available in various head styles, drive types, thread sizes, and lengths. Material options include stainless steel and carbon steel, with different surface finishes available to meet specific corrosion resistance and application requirements.

 

As a professional SEMS screws manufacturer in China, we provide standard and custom double SEMS screws based on customer drawings, samples, and technical specifications. Whether you need OEM fastening solutions or bulk orders, contact us to discuss your washer configurations, material requirements, and production needs for a competitive quotation.
