A screw is a type of fastener, in some ways similar to a bolt, typically made of metal, and characterized by a helical ridge, known as a male thread (external thread). Screws are used to fasten materials by digging in and wedging into a material when turned, while the thread cuts grooves in the fastened material that may help pull fastened materials together and prevent pull-out. There are many screws for a variety of materials; those commonly fastened by screws include wood, sheet metal, and plastic.

SEMS screws combine two separate parts into one pre-assembled, low cost fastener. With washers under the head, SEMS screws are fast, permanent, and easily adaptable to many applications.

A fastener with a built in washer is called a SEM or SEMS, short for pre-asSEMbled. It could be fitted on either a tapered or non-tapered shank

Sems screws are machine screws that can have one or more flat or lock washer under the head already assembled.
