What is the maximum load that high strength bolts can withstand?

Author: admin / 2023-04-21

The maximum load that high strength bolts can withstand depends on various factors such as the size, type, and grade of the bolt, the material of the connected components, the joint design, and the loading conditions.

In general, high strength bolts are designed to withstand high tensile and shear forces, and their load-bearing capacity can range from a few kilonewtons to several hundred kilonewtons. For example, a typical high strength bolt of size M20 (diameter of 20 mm) and grade 8.8 (a common high strength grade) can withstand a maximum tensile load of around 140 kilonewtons and a maximum shear load of around 90 kilonewtons.

However, it is important to note that the maximum load that a bolt can withstand should be determined by a qualified engineer or by following industry standards and guidelines. Overloading a bolt can cause it to fail catastrophically, leading to serious consequences. Therefore, it is important to ensure that the bolts used in a particular application are properly designed and installed to withstand the expected loads.
