Strength is the bearing capacity per unit area, is an indicator.
Formula: Bearing capacity = strength x area;
Threaded bolt, M24 bolt cross-sectional area is not the diameter of the circular area of 24, but 353 mm2, called the effective area.
Normal Bolt Grade C (grades 4.6 and 4.8) The tensile strength is 170 N / mm 2.
Then the carrying capacity is: 170×353 = 60010N. Conversion, 1 ton equivalent to 1000KG, equivalent to 10000N, then M24 bolts that can withstand about 6 […]
