For years, the Valley Fastener Group has made it a priority to manufacture and maintain a high-quality stock of SEMs screws for our customers. SEMs are fasteners that incorporate a separate washer held by the threads on a fastener. Most commonly, if it is necessary that a mating material does not rotate with a fastener, this is when SEMs come in handy. Valley Fastener manufactures both inch and metric SEMs screws in a variety of sizes. We have the ability to run sems screws up to 1/4 inch diameter.

With a knowledgeable and experienced staff of manufacturers and the utilization of our 150 state of the art machines, the Valley Fastener Group has extensive capabilities in manufacturing both inch and metric SEMs fasteners for your specific application requirements. Our SEMs are dependable and versatile. The incorporated washer can be many different styles depending on the application, including Conical, Flat, Square Cone, or Internal/External lock.

With our SEMs, as with all the products we provide, Valley puts a heavy emphasis on quality, from the manufacturing process all the way to the shipping dock. Contact our group today to learn more and place an order for SEMs, and we will match you with the right product for your project.
