SEMS Screws

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.
