SEMS Screws
SEMS screws are pre-assembled fasteners combining a screw and captive washer in a single unit. The integrated washer distributes load across a wider surface area, improving clamping performance and reducing installation time. Commonly used in manufacturing, electrical assemblies, and applications where vibration resistance and efficiency are important.
