Manufacturer of Hydraulic Bolting Solutions The chart of recommended bolt tightening force The datas are mainly suitable for bolt tensioner and hydraulic nut. Strength grade General structural steel Mechanical construction steel Chrome molybdenum alloy steel Ni-Cr-Mo alloy steel Ni-Cr-Mo alloy steel Attention: The data in the chart is measured under 60% yield limit of the bolt, the recommended tightening torque is 70-80% of above data. For example, for M42 grade 10.8 bolt, the tightening torque is 605*(70-80)% = 423.5-484KN.
