Abstract: A method and a plant for manufacturing fasteners, in particular screws, along an automated production line; the method comprising the following steps: feeding the raw material made of titanium; heating the raw material to a predefined temperature; cutting one or more pieces of a predefined length, in succession, from the heated raw material; deforming plastically each piece by means of one or more finishing stations, so as to obtain a fastener; heating, during the deforming step, the material that passes through each workstation to a predefined temperature; wherein the material manipulated along the production line during the feeding, heating, and deforming steps is automatically transported along the production line.

Abstract: A signal acquiring method is provided using a plurality of fasteners with sensing elements configured to generate electrical signals as a function of the operating conditions of a plurality of readers, and an acquiring system. The method involves generating one or more electrical signals by means of the sensing elements, mechanically connecting the readers to the fasteners, and transferring the signals to the acquiring system by means of the readers.

Abstract: Tie bolt and process for making such tie bolt having a shank and a nut, in particular a dead nut; wherein the nut is tightened and locked around a respective end of the shank, so as to form an indivisible body.

Abstract: A fixing element, a use of a sensitive element to detect a flow of heat on the inside of mechanical organs; wherein the fixing element, in particular a screw or a stud, has a body and a sensitive element, which is designed to detect a difference of temperature between a first and a second area of the body of the fixing element, so as to determine, as a function of said difference of temperature, a flow of heat that flows through the fixing element and the mechanical organ where it is installed.
