This paper demonstrates the jig set for the crash test and the crash test results of the tensionbolts with respect to an applied pre-tension. The tension and shear bolts are adopted at Light CollisionSafety Devices as a mechanical fuse when tension bolts reach designed failure load. The kineticenergy due to the crash is absorbed by secondary energy absorbing devices after the fracture of tensionbolts. One tension bolt was designed to be failed at the load of 375 kN. The jig set was designed toconvert a compressive loading to a tensile loading and installed at the high speed crash tester. Thestrain gauges were attached at the parallel section of the tension bolts to measure the level of thepre-tension acting on the tension bolts. Crash tests were performed with a barrier whose mass was 250kg and initial speed of the barrier was 9.5 m/sec. The result includes the load response of the tensionbolts during both the crash tests and finite element analysis
