SEMS Screws

DESCRIPTION:

A SEMS screw, short for “Screw and External Metal Washer Assembly,” is a type of fastener that combines a screw or threaded fastener with an attached external metal washer. The washer is preassembled onto the screw to provide certain advantages during installation and use:

1. Load Distribution: The external metal washer helps distribute the load or pressure more evenly over the surface being fastened. This helps prevent damage to the material and ensures a secure and stable connection.
2. Vibration Resistance: SEMS screws are often used in applications where resistance to vibration or loosening due to external forces is important. The washer’s design, when properly installed, can help prevent the screw from coming loose.
3. Assembly Efficiency: SEMS screws simplify the assembly process because the washer is already attached to the screw. This eliminates the need to manually place a separate washer during installation, saving time and reducing the risk of assembly errors.

SEMS screws are commonly used in various industries and applications where secure and reliable fastening is crucial, such as automotive, electronics, manufacturing, and construction.

They come in different sizes and configurations to meet specific requirements and can have various types of washers, such as flat, split, and internal-toothed washers, depending on the intended use.
