We tested it with our hydraulic press. First we tightened the bolts in the correct cross (tic-tac) pattern. Then in a circular pattern. Then we removed one bolt. Then we mixed torque levels completely wrong. And finally we torqued a bolt until it snapped. Results were… unexpected. In this video we test: – 8 bolts tightened correctly – 8 bolts tightened in circular pattern – 7 bolts (one missing) – Mixed torque levels (too tight / hand tight) – 8.8 vs 10.8 grade bolts – Torque failure in Nm Maximum load reached: ~45 tons Does tightening pattern increase strength? Or is it only about keeping bolts evenly loaded? Let us know in the comments — many of you know more about bolt mechanics than we do.
