Abstract
The present subject matter relates to screws for tool-less assembling of an electronic board on a chassis. In an example implementation, the screw comprises a threaded pin to secure the screw on the electronic board using a nut. The screw also comprises a screw head that fits into a hook on the chassis when the electronic board is assembled on the chassis. The screw further comprises a flange integral to the screw and positioned between the threaded pin and the screw head. The flange is extended radially to support the electronic board and is positioned at a distance from the screw head based on a gap to be maintained between the electronic board and the chassis.

A coupling unit for tool-less assembling of an electronic board on a chassis, the coupling unit comprising:
- a screw including:
- a threaded pin at one end of the screw;
- a screw head at another end of the screw;
- a flange integral to the screw and positioned between the threaded pin and the screw head;
- the flange being extended radially to support the electronic board and being positioned at a distance from the screw head based on a gap to be maintained between the electronic board and the chassis;
- a corresponding hook installed on the chassis to receive the screw head;
- and
- a hex-nut couplable to the threaded pin of the screw for securing the screw on the electronic board,
- wherein the flange of the screw is separated from the threaded pin by a first cylindrical portion of the screw, and wherein the flange of the screw is separated from the screw head by a second cylindrical portion of the screw and wherein the first cylindrical portion has a diameter that is adapted to be substantially equal to an inner diameter of a hole in the electronic board through which the screw is pass.
A coupling unit for tool-less assembling of an electronic board on a chassis, the coupling unit comprising:
- a screw including:
