<p>The most recent developments in steel construction mainly concern connections, and in particular high-strength preloaded bolts. The reason why these last are so widely used is that they not only may generate an enormous clamping load over a small area, but they also enable the number of bolts in the connection to be reduced, thus reducing joint dimensions and the weight of the structure not to mention the fact that they can be dismounted. Today, a wide range of High-Strength preloaded bolts exists. The best-known is the High Strength Bolt, rivaled by the High Strength Tension Control Bolt and Huck Bob Tail, whose ancestor is the Huck-Fit. Huck bolts are quick and easy to install, saving over 40% in installation time, and above all offer high strength due to the absence of torsion in the bolt. Because of their excellent vibration behavior, swaged bolts are used to assemble truck trailers and railway equipment. They are also found in steel construction, for bridges and for large steel frameworks, particularly where overhead cranes are involved. Thanks to their specific installation process, crimped bolts cannot loosen, unlike traditional bolts which may need re-tightening. This serviceability is an important asset, since it guarantees safety and reduces maintenance, even under extreme conditions such as repeated shocks for instance. More, crimped bolts can be installed quickly using specialized tools, which guarantee clamping pressure irrespective of a worker's ability to apply the required torque. In this paper, a tensile strength study was carried out in the laboratory on the prestressed Huck-Fit swaged bolt, followed by a finite element modelling. </p>
