Product Description


Hex Head SEMS Screws with Spring Washer is a popular fastener used in various industries. The SEMS screw is a pre-assembled fastener that includes a captive washer or multiple washers held in place by the screw thread. The difference between a SEMS screw and a regular screw is the washer integrated into the screw's design to streamline and add convenience to the assembly process.


The Hex Head SEMS Screws with Spring Washer is a fantastic product that comes with numerous benefits. The screws are designed with a hexagonal head and a spring washer that is placed under the head. The spring washer functions to provide resistance to loosening, which means that after the screw has been tightened properly, it will remain in place. In simple terms, the spring washer prevents unnecessary movement, making the whole assembly more secure.


The hexagonal head also provides excellent grip for the tool being used to tighten or loosen it. This type of head shape is particularly important for high torque applications, enabling users to achieve maximum tightness while ensuring the screw can still be removed if needed.

The outer surface of the screws generally has an iron-zinc alloy, and after heating, this substance will be converted into purified zinc without iron, which increases the service life and corrosion resistance of the screws.
