Abstract: The present disclosure provides an improved screw and method of manufacturing thereof. The method comprising the steps of manufacturing 101 the screw body by cold forging process using ferrous alloy, making 102 a hole 301 on the screw head 201 to form a base of the hole and a wall thickness 501 of the screw head 201 for providing an internal drive, forming 103 a layer 602 of hard ferrous alloy in the hole 301 with the screw head 201 wherein the layer 602 having high hardness than the screw body 200, optionally smoothening 104 the layer 602 using a conventional process and machining 105 the layer 602 to obtain the internal drive 601 thereby achieving increase in hardness and wear-resistance of the internal drive 601.
