Abstract
A threaded bolt having a proximal head end and a distal insertion end, the proximal head end and the distal insertion end are each provided with a single, exposed radial measurement plane, the radial measurement plane at the distal insertion end is formed by a flat bottom of a recess at the distal insertion end, the recess is bounded by a circumferential wall which at a point of change transitions into the flank of the distal end via a buckle, and wherein the radial measurement planes are for use in ultrasonic length measurement for determining the tension in the threaded bolt after it has been used in a connection.

Threaded bolt for use in ultrasonic measurement for determining the tension in the threaded bolt after it has been used in a connection having a proximal head end and a distal insertion end extended about a shank having a substantially cylindrical body, the proximal head end and the distal insertion end are each provided with a single, exposed radial measurement plane, the radial measurement plane at the distal insertion end is formed by a flat bottom of a freely exposed recess at the distal insertion end, the recess is bounded by a first circumferential plane which at a point of change transitions into a second circumferential plane of the distal end via a buckle, and wherein a sensor will be placed against the measurement plane at the head end to measure the distance between the measurement planes.
