Technical Parameters
Sem bolts, also known as SEMS screws, are a type of pre-assembled fastener that combines a screw with a captive washer. These washer screws are designed for efficiency and convenience, as the captive washer is permanently affixed to the screw, preventing loss during handling or assembly. SEMS screws are widely used in various industries including automotive, electronics, and machinery, where secure fastening and time-saving installation are essential. The integrated washer enhances load distribution and reduces the risk of loosening, making sem bolts a reliable solution for repeated or high-vibration applications.
