SEMS Bolts

DESCRIPTION:

A SEMS bolt (SEMS: External Metal Washer) is a type of fastener that consists of two main components: a bolt and an external metal washer. The washer is attached to the bolt in such a way that it remains in place during installation and provides several benefits:

1. Load Distribution: The external washer helps distribute the load or pressure more evenly over the surface being fastened. This can reduce the risk of damage to the material and ensure a secure connection.
2. Vibration Resistance: SEMS bolts are often used in applications where vibration resistance is important. The washer’s design, when properly installed, can help prevent the bolt from loosening due to vibrations or external forces.
3. Simplified Assembly: Using SEMS bolts can simplify the assembly process since there’s no need to manually place a separate washer on the bolt during installation. This can save time and reduce the risk of assembly errors.

SEMS bolts are used in various industries and applications where secure and reliable fastening is essential, such as automotive, electronics, and manufacturing. They are available in different sizes and configurations to suit specific needs.

Other names: SEM bolt, hex head sem bolt, hexagon head sem screw bolt, hex head bolts SEM screws, SEM screws.
