Using fastening components together has proven to bring increased effectiveness and more robust assembly. Washers have been long known to function along with screws for a significant purpose. Since the idea of combining two components has proven more effective, pre-assembling them has been innovated into history. Sem screws were fabricated to eliminate the conjunction of washers and screws.

The fastener manufacturing industry has now captivated the innovative and versatile use of sem screws in different applications. Sem screws are machine screws manufactured with a single or more type of the washer under the head. Flat or lock washers are the common types. While there is a variety of head styles like pan, hex head, hex washer head, internal, external, conical, double sems, cheese, cap, etc.
