Screw Connectors

Screw connectors use a screw to establish conductivity and act as terminals to provide secure, quick and reversible connections. Depending on the screw connector design, the wire may be wrapped under the screw head or fastened to metal. When the screw is tightened, the wire is forced onto the conductive material. Setscrew connectors fasten wires to the side of the metal tube and are available in insulated and noninsulated forms. These connectors are ideal in dry locations when bonding thin-wall conduit to an electrical junction box. Many setscrew connectors are made of zinc-plated steel for durable protection and corrosion resistance.
