machine screw

Small threaded bolt

A machine screw is a threaded fastener designed to fit into a pre-tapped hole or be secured with a nut, typically with a slotted or Phillips head.

Unlike wood screws, machine screws have uniform threads along their full length and are used to join metal parts or fasten components to machinery: The cover plate is held on by four machine screws.
