Two paired screw terminals, typically used for connecting ceiling-mounted light fixtures. Screw terminals are used extensively in building wiring for the distribution of electricity - connecting electrical outlets, luminaires and switches to the mains, and for directly connecting major appliances such as clothes dryers and ovens drawing in excess of 15 amperes.
The screw terminals are hollow and allow up to at least three 1 mm (CSA) wires, twisted together, to be inserted to a depth of up to 10 millimetres (0.39 in) and secured with a set screw. The contact terminal set screws are installed at a slight angle to allow easier screwdriver access after the switch mechanism has been installed into a wall ...
IEC metric screw sized connectors is a family of electrical connectors defined by IEC that are named according to their ISO metric screw thread, namely M5, M8 and M12. [1] The number gives their outer screw thread diameter in millimeters as with the identically named screws.
Diagram of a thread angle. In mechanical engineering, the thread angle of a screw is the included angle between the thread flanks, measured in a plane containing the thread axis. [1] This is a defining factor for the shape of a screw thread. Standard values include:
A Robertson screw, also known as a square screw [1] or Scrulox, [2] is a type of screw with a square-shaped socket in the screw head and a corresponding square protrusion on the tool. Both the tool and socket have a slight taper .

Terminal symbol A terminal strip, to which wires can be soldered. A terminal is the point at which a conductor from a component, device or network comes to an end. [1] Terminal may also refer to an electrical connector at this endpoint, acting as the reusable interface to a conductor and creating a point where external circuits can be connected.
Most screw threads are oriented so that when seen from above, the screw shaft moves away from the viewer (the screw is tightened) when turned in a clockwise direction. [ 21 ] [ 22 ] This is known as a right-handed ( RH ) thread, because it follows the right hand grip rule : when the fingers of the right hand are curled around the shaft in the ...
