Document Type and Number:
Japanese Patent JP6810142
Kind Code:
B2
Abstract:
Screw having a head and a threaded cylindrical body, the head being provided with strain gauges arranged so as to be deformed in order to measure a stress within the screw, the gauges being connected or able to be connected to a power supply and to a determination unit for determining the value of at least one inner stress from the deformations of the gauges. The head has, on the upper face thereof, a conical hole having a revolution axis that is aligned with the revolution axis of the cylindrical body. The gauges are arranged on the wall of the conical hole so as to be deformed together with the conical hole and are oriented to measure at least one type of inner stress selected among the tension and the shearing.
